GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also counts
as the successor of the GNU Library Public License, version 2, hence
the version number 2.1.]
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some
specially designated software packages--typically libraries--of the
Free Software Foundation and other authors who decide to use it. You
can use it too, but we suggest you first think carefully about whether
this license or the ordinary General Public License is the better
strategy to use in any particular case, based on the explanations below.
When we speak of free software, we are referring to freedom of use,
not price. Our General Public Licenses are designed to make sure that
you have the freedom to distribute copies of free software (and charge
for this service if you wish); that you receive source code or can get
it if you want it; that you can change the software and use pieces of
it in new free programs; and that you are informed that you can do
these things.
To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights. These restrictions translate to certain responsibilities for
you if you distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get the source
code. If you link other code with the library, you must provide
complete object files to the recipients, so that they can relink them
with the library after making changes to the library and recompiling
it. And you must show them these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal
permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that
there is no warranty for the free library. Also, if the library is
modified by someone else and passed on, the recipients should know
that what they have is not the original version, so that the original
author's reputation will not be affected by problems that might be
introduced by others.
Finally, software patents pose a constant threat to the existence of
any free program. We wish to make sure that a company cannot
effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder. Therefore, we insist that
any patent license obtained for a version of the library must be
consistent with the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the
ordinary GNU General Public License. This license, the GNU Lesser
General Public License, applies to certain designated libraries, and
is quite different from the ordinary General Public License. We use
this license for certain libraries in order to permit linking those
libraries into non-free programs.
When a program is linked with a library, whether statically or using
a shared library, the combination of the two is legally speaking a
combined work, a derivative of the original library. The ordinary
General Public License therefore permits such linking only if the
entire combination fits its criteria of freedom. The Lesser General
Public License permits more lax criteria for linking other code with
the library.
We call this license the "Lesser" General Public License because it
does Less to protect the user's freedom than the ordinary General
Public License. It also provides other free software developers Less
of an advantage over competing non-free programs. These disadvantages
are the reason we use the ordinary General Public License for many
libraries. However, the Lesser license provides advantages in certain
special circumstances.
For example, on rare occasions, there may be a special need to
encourage the widest possible use of a certain library, so that it becomes
a de-facto standard. To achieve this, non-free programs must be
allowed to use the library. A more frequent case is that a free
library does the same job as widely used non-free libraries. In this
case, there is little to gain by limiting the free library to free
software only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free
programs enables a greater number of people to use a large body of
free software. For example, permission to use the GNU C Library in
non-free programs enables many more people to use the whole GNU
operating system, as well as its variant, the GNU/Linux operating
system.
Although the Lesser General Public License is Less protective of the
users' freedom, it does ensure that the user of a program that is
linked with the Library has the freedom and the wherewithal to run
that program using a modified version of the Library.
The precise terms and conditions for copying, distribution and
modification follow. Pay close attention to the difference between a
"work based on the library" and a "work that uses the library". The
former contains code derived from the library, whereas the latter must
be combined with the library in order to run.
GNU LESSER GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other
program which contains a notice placed by the copyright holder or
other authorized party saying it may be distributed under the terms of
this Lesser General Public License (also called "this License").
Each licensee is addressed as "you".
A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work
which has been distributed under these terms. A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language. (Hereinafter, translation is
included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for
making modifications to it. For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control compilation
and installation of the library.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it). Whether that is true depends on what the Library does
and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.
You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.
2. You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices
stating that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no
charge to all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a
table of data to be supplied by an application program that uses
the facility, other than as an argument passed when the facility
is invoked, then you must make a good faith effort to ensure that,
in the event an application does not supply such function or
table, the facility still operates, and performs whatever part of
its purpose remains meaningful.
(For example, a function in a library to compute square roots has
a purpose that is entirely well-defined independent of the
application. Therefore, Subsection 2d requires that any
application-supplied function or table used by this function must
be optional: if the application does not supply it, the square
root function must still compute square roots.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Library, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Library.
In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License. (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.) Do not make any other change in
these notices.
Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.
If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a "work that uses the Library". Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library". The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library. The
threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work. (Executables containing this object code plus portions of the
Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also combine or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License. Also, you must do one
of these things:
a) Accompany the work with the complete corresponding
machine-readable source code for the Library including whatever
changes were used in the work (which must be distributed under
Sections 1 and 2 above); and, if the work is an executable linked
with the Library, with the complete machine-readable "work that
uses the Library", as object code and/or source code, so that the
user can modify the Library and then relink to produce a modified
executable containing the modified Library. (It is understood
that the user who changes the contents of definitions files in the
Library will not necessarily be able to recompile the application
to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (1) uses at run time a
copy of the library already present on the user's computer system,
rather than copying library functions into the executable, and (2)
will operate properly with a modified version of the library, if
the user installs one, as long as the modified version is
interface-compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for at
least three years, to give the same user the materials
specified in Subsection 6a, above, for a charge no more
than the cost of performing this distribution.
d) If distribution of the work is made by offering access to copy
from a designated place, offer equivalent access to copy the above
specified materials from the same place.
e) Verify that the user has already received a copy of these
materials or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it. However, as a special exception,
the materials to be distributed need not include anything that is
normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.
It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system. Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.
7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work
based on the Library, uncombined with any other library
facilities. This must be distributed under the terms of the
Sections above.
b) Give prominent notice with the combined library of the fact
that part of it is a work based on the Library, and explaining
where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate your
rights under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Library or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties with
this License.
11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all. For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License may add
an explicit geographical distribution limitation excluding those countries,
so that distribution is permitted only in or among countries not thus
excluded. In such case, this License incorporates the limitation as if
written in the body of this License.
13. The Free Software Foundation may publish revised and/or new
versions of the Lesser General Public License from time to time.
Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation. If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this. Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).
To apply these terms, attach the following notices to the library. It is
safest to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
<one line to give the library's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This library is free software; you can redistribute it and/or

Basic Installation
==================
These are generic installation instructions.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions. Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, a file
`config.cache' that saves the results of its tests to speed up
reconfiguring, and a file `config.log' containing compiler output
(useful mainly for debugging `configure').
If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release. If at some point `config.cache'
contains results you don't want to keep, you may remove or edit it.
The file `configure.in' is used to create `configure' by a program
called `autoconf'. You only need `configure.in' if you want to change
it or regenerate `configure' using a newer version of `autoconf'.
The simplest way to compile this package is:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system. If you're
using `csh' on an old version of System V, you might need to type
`sh ./configure' instead to prevent `csh' from trying to execute
`configure' itself.
Running `configure' takes awhile. While running, it prints some
messages telling which features it is checking for.
2. Type `make' to compile the package.
3. Optionally, type `make check' to run any self-tests that come with
the package.
4. Type `make install' to install the programs and any data files and
documentation.
5. You can remove the program binaries and object files from the
source code directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile the package for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that
the `configure' script does not know about. You can give `configure'
initial values for variables by setting them in the environment. Using
a Bourne-compatible shell, you can do that on the command line like
this:
CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
Or on systems that have the `env' program, you can do it like this:
env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you must use a version of `make' that
supports the `VPATH' variable, such as GNU `make'. `cd' to the
directory where you want the object files and executables to go and run
the `configure' script. `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'.
If you have to use a `make' that does not supports the `VPATH'
variable, you have to compile the package for one architecture at a time
in the source code directory. After you have installed the package for
one architecture, use `make distclean' before reconfiguring for another
architecture.
Installation Names
==================
By default, `make install' will install the package's files in
`/usr/local/bin', `/usr/local/man', etc. You can specify an
installation prefix other than `/usr/local' by giving `configure' the
option `--prefix=PATH'.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
give `configure' the option `--exec-prefix=PATH', the package will use
PATH as the prefix for installing programs and libraries.
Documentation and other data files will still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like `--bindir=PATH' to specify different values for particular
kinds of files. Run `configure --help' for a list of the directories
you can set and what kinds of files go in them.
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
Optional Features
=================
Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System). The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.
For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.
Specifying the System Type
==========================
There may be some features `configure' can not figure out
automatically, but needs to determine by the type of host the package
will run on. Usually `configure' can figure that out, but if it prints
a message saying it can not guess the host type, give it the
`--host=TYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name with three fields:
CPU-COMPANY-SYSTEM
See the file `config.sub' for the possible values of each field. If
`config.sub' isn't included in this package, then this package doesn't
need to know the host type.
If you are building compiler tools for cross-compiling, you can also
use the `--target=TYPE' option to select the type of system they will
produce code for and the `--build=TYPE' option to select the type of
system on which you are compiling the package.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share,
you can create a site shell script called `config.site' that gives
default values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists. Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.
Operation Controls
==================
`configure' recognizes the following options to control how it
operates.
`--cache-file=FILE'
Use and save the results of the tests in FILE instead of
`./config.cache'. Set FILE to `/dev/null' to disable caching, for
debugging `configure'.
`--help'
Print a summary of the options to `configure', and exit.
`--quiet'
`--silent'
`-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to `/dev/null' (any error
messages will still be shown).
`--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
`configure' can determine that directory automatically.
`--version'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`configure' also accepts some other, not widely useful, options.

The libsndfile Modules for GNU Octave
=====================================
These modules are currently known to work with version 3.0 of GNU Octave on
Linux. They have not been tested elsewhere.
Build Requirements
------------------
In order to build these libsndfile related modules for GNU Octave on a Debian
GNU/Linux (or Debian derived) system, you will need (on top of what is normally
required to build libsndfile) the package:
octaveX.Y-headers
where X.Y matches the version number of your installation of GNU Octave.
The configure script in the top level libsndfile directory will detect the
presence and correct versions of the Octave build tools. The building of these
modules will only go ahead if everything is correct.

This is libsndfile, 1.0.25
libsndfile is a library of C routines for reading and writing
files containing sampled audio data.
The src/ directory contains the source code for library itself.
The doc/ directory contains the libsndfile documentation.
The examples/ directory contains examples of how to write code using
libsndfile.
The tests/ directory contains programs which link against libsndfile
and test its functionality.
The src/GSM610 directory contains code written by Jutta Degener and Carsten
Bormann. Their original code can be found at :
http://kbs.cs.tu-berlin.de/~jutta/toast.html
The src/G72x directory contains code written and released by Sun Microsystems
under a suitably free license.
The src/ALAC directory contains code written and released by Apple Inc and
released under the Apache license.
LINUX
-----
Whereever possible, you should use the packages supplied by your Linux
distribution.
If you really do need to compile from source it should be as easy as:
./configure
make
make install
Since libsndfile optionally links against libFLAC, libogg and libvorbis, you
will need to install appropriate versions of these libraries before running
configure as above.
UNIX
----
Compile as for Linux.
Win32/Win64
-----------
The default Windows compilers are nowhere near compliant with the 1999 ISO
C Standard and hence not able to compile libsndfile.
Please use the libsndfile binaries available on the libsndfile web site.
MacOSX
------
Building on MacOSX should be the same as building it on any other Unix.
CONTACTS

# libsndfile
libsndfile is a C library for reading and writing files containing sampled audio
data.
## Hacking
The canonical source code repository for libsndfile is at
[https://github.com/erikd/libsndfile/][github].
You can grab the source code using:
$ git clone git://github.com/erikd/libsndfile.git
Building on Linux, OSX and Windows (Using GNU GCC) will require a number of GNU
and other Free and Open Source Software tools including:
* [Autoconf][autoconf]
* [Autogen][autogen]
* [Automake][automake]
* [Libtool][libtool]
* [Pkgconfig][pkgconfig]
* [Python][python]
If you are on Linux, its probably best to install these via your Linux
distribution's package manager.
If you want to compile libsndfile with support for formats like FLAC and
Ogg/Vorbis you will also need to install the following optional libraries:
* [FLAC][flac]
* [libogg][libogg]
* [libvorbis][libvorbis]
Support for these extra libraries is an all or nothing affair. Unless all of
them are installed none of them will be supported.
$ ./autogen.sh
Running `autogen.sh` also installs a git pre-commit hook. The pre-commit hook
is run each time a user tries to commit and checks code about to be committed
against coding guidelines.
Nest step is to run configure, with the following configure options being
recommended for anyone contemplating sending libsndfile patches:
$ ./configure --enable-gcc-werror
Finally libsndfile can be built and tested:
$ make
$ make check
## Submitting Patches.
* Patches should pass all pre-commit hook tests.
* Patches should always be submitted via a either Github "pull request" or a
via emailed patches created using "git format-patch".
* Patches for new features should include tests and documentation.
* Patches to fix bugs should either pass all tests, or modify the tests in some
sane way.
* When a new feature is added for a particular file format and that feature
makes sense for other formats, then it should also be implemented for one
or two of the other formats.

@ -1,42 +0,0 @@
Here's a list of what I (erikd AT mega-nerd DOT com) think needs to be
done. The list is by no means exhaustive and people are encouraged to
email me with suggestions.
o Add pipe in/out capabilities. libsndfile should be able to read
its input from a pipe and write its output to a pipe.
o Add checks of the error state after fseek???? Use ferror ().
o Modify tests/lossy_comp_test.c to add tests for stereo files.
o Testing compilation and correctness on more platforms.
o Improve testing routines. Must test all combinations of inputs
and outputs.
o Test sf_seek function on write???
o Add more sound file formats. People should contact me with their
requirements.
o Add support for accessing sound formats with multiple audio
data sections (ie samples within tracker files, Soundfont II and
multi-sample sampler formats).
o Add an interface to allow reading and writing of sample loop points
and other info within AIFF and other file formats. This must be a
general solution.
o Improve documentation. Is HTML documentation good enough?
o Look into the possibility of optional sample rate convert on file
read.
As I am the person who knows libsndfile best, I can probably implement
any new features faster than anybody else (and you can spend your time
writing applications with libsndfile). All I need is some
documentation and some sample files. Please contact me before emailing
me documentation and sample files. I would much rather pull them off
the web than have them clogging up my email inbox.

Notes on Using the Pre-compiled libsndfile DLL.
===============================================
In order to use this pre-compiled DLL with Visual Studio, you will need to
generate a .LIB file from the DLL.
This can be achieved as follows:
1) In a CMD window, change to the directory containing this file and
run the command:
lib /machine:i386 /def:libsndfile-1.def
You now have two files:
libsndfile-1.dll
libsndfile-1.lib
to be used with VisualStudio.
If the lib command fails with a command saying "'lib' is not recognized as
an internal or external command, operable program or batch file", you need
to find the location of "lib.exe" and add that directory to your PATH
environment variable. Another alternative is to use the "Visual Studio 2005
Command Prompt" Start menu item:
Start ->
All Programs ->
Visual Studio 2005 ->
Visual Studio Tools ->
Visual Studio 2005 Command Prompt
If for some reason these instructions don't work for you or you are still
not able to use the libsndfile DLL with you project, please do not contact
the main author of libsndfile. Instead, join the libsndfile-users mailing
list :
http://www.mega-nerd.com/libsndfile/lists.html
and ask a question there.

# increment revision (`c:r:a' becomes `c:r+1:a').
# 4. If any interfaces have been added, removed, or changed since the last update,
# increment current, and set revision to 0.
# 5. If any interfaces have been added since the last public release, then increment
# age.

<A NAME="Q001"></A>
<H2><BR/><B>Q1 : Do you plan to support XYZ codec in libsndfile?</B></H2>
<P>
If source code for XYZ codec is available under a suitable license (LGPL, BSD,
MIT etc) then yes, I'd like to add it.
</P>
<P>
If suitable documentation is available on how to decode and encode the format
then maybe, depending on how much work is involved.
</P>
<P>
If XYZ is some proprietary codec where no source code or documentation is
available then no.
</P>
<P>
So if you want support for XYZ codec, first find existing source code or
documentation.
If you can't find either then the answer is no.
</P>

<A NAME="Q002"></A>
<H2><BR/><B>Q2 : In version 0 the SF_INFO struct had a pcmbitwidth field
but version 1 does not. Why?</B></H2>
<P>
This was dropped for a number of reasons:
</P>
<UL>
<LI> pcmbitwidth makes little sense on compressed or floating point formats
<LI> with the new API you really don't need to know it
</UL>
<P>
As documented
<A HREF="api.html#note1">here</A>
there is now a well defined behaviour which ensures that no matter what the
bit width of the source file, the scaling always does something sensible.
This makes it safe to read 8, 16, 24 and 32 bit PCM files using sf_read_short()
and always have the optimal behaviour.
</P>
<!-- ========================================================================= -->
<A NAME="Q003"></A>
<H2><BR/><B>Q3 : Compiling is really slow on MacOS X. Why?</B></H2>
<P>
When you configure and compile libsndfile, it uses the /bin/sh shell for a number
of tasks (ie configure script and libtool).
Older versions of OS X (10.2?) shipped a really crappy Bourne shell as /bin/sh
which resulted in <b>really</b> slow compiles.
Newer version of OS X ship GNU Bash as /bin/sh and this answer doesn't apply in that
case.
</P>
<P>
To fix this I suggest that you install the GNU Bash shell, rename /bin/sh to
/bin/sh.old and make a symlink from /bin/sh to the bash shell.
Bash is designed to behave as a Bourne shell when is is called as /bin/sh.
</P>
<P>
When I did this on my iBook running MacOS X, compile times dropped from 13 minutes
to 3 minutes.
</P>
<!-- ========================================================================= -->
<A NAME="Q004"></A>
<H2><BR/><B>Q4 : When trying to compile libsndfile on Solaris I get a "bad
substitution" error on linking. Why?</B></H2>
<P>
It seems that the Solaris Bourne shell disagrees with GNU libtool.
</P>
<P>
To fix this I suggest that you install the GNU Bash shell, rename /bin/sh to
/bin/sh.old and make a symlink from /bin/sh to the bash shell.
Bash is designed to behave as a Bourne shell when is is called as /bin/sh.
</P>
<!-- ========================================================================= -->
<A NAME="Q005"></A>
<H2><BR/><B>Q5 : Why doesn't libsndfile do interleaving/de-interleaving?</B></H2>
<P>
This problem is bigger than it may seem at first.
</P>
<P>
For a stereo file, it is a pretty safe bet that a simple interleaving/de-interleaving
could satisfy most users.
However, for files with more than 2 channels this is unlikely to be the case.
If the user has a 4 channel file and want to play that file on a stereo output
sound card they either want the first 2 channels or they want some mixed combination
of the 4 channels.
</P>
<P>
When you add more channels, the combinations grow exponentially and it becomes
increasingly difficult to cover even a sensible subset of the possible combinations.
On top of that, coding any one style of interleaver/de-interleaver is trivial, while
coding one that can cover all combinations is far from trivial.
This means that this feature will not be added any time soon.
</P>
<!-- ========================================================================= -->
<A NAME="Q006"></A>
<H2><BR/><B>Q6 : What's the best format for storing temporary files?</B></H2>
<P>
When you want to store temporary data there are a number of requirements;
</P>
<UL>
<LI> A simple, easy to parse header.
<LI> The format must provide the fastest possible read and write rates (ie
avoid conversions and encoding/decoding).
<LI> The file format must be reasonably common and playable by most players.
<LI> Able to store data in either endian-ness.
</UL>
<P>
The format which best meets these requirements is AU, which allows data to be
stored in any one of short, int, float and double (among others) formats.
</P>
<P>
For instance, if an application uses float data internally, its temporary files
should use a format of (SF_ENDIAN_CPU | SF_FORMAT_AU | SF_FORMAT_FLOAT) which
will store big endian float data in big endian CPUs and little endian float data
on little endian CPUs.
Reading and writing this format will not require any conversions or byte swapping
regardless of the host CPU.
</P>
<!-- ========================================================================= -->
<A NAME="Q007"></A>
<H2><BR/><B>Q7 : On Linux/Unix/MaxOS X, what's the best way of detecting the presence
of libsndfile using autoconf?</B></H2>
<P>
libsndfile uses the pkg-config (man pkg-config) method of registering itself with the
host system.
The best way of detecting its presence is using something like this in configure.ac
(or configure.in):
</P>
<PRE>
PKG_CHECK_MODULES(SNDFILE, sndfile >= 1.0.2, ac_cv_sndfile=1, ac_cv_sndfile=0)
AC_DEFINE_UNQUOTED([HAVE_SNDFILE],${ac_cv_sndfile},
[Set to 1 if you have libsndfile.])
AC_SUBST(SNDFILE_CFLAGS)
AC_SUBST(SNDFILE_LIBS)
</PRE>
<P>
This will automatically set the <B>SNDFILE_CFLAGS</B> and <B>SNDFILE_LIBS</B>
variables which can be used in Makefile.am like this:
</P>
<PRE>
SNDFILE_CFLAGS = @SNDFILE_CFLAGS@
SNDFILE_LIBS = @SNDFILE_LIBS@
</PRE>
<P>
If you install libsndfile from source, you will probably need to set the
<B>PKG_CONFIG_PATH</B> environment variable as suggested at the end of the
libsndfile configure process. For instance on my system I get this:
</P>

Installation directories :

the addition of "/usr/local/lib/pkgconfig" to the
PKG_CONFIG_PATH environment variable.

<A NAME="Q008"></A>
<H2><BR/><B>Q8 : I have libsndfile installed and now I want to use it. I just want
a simple Makefile! What do I do?</B></H2>
<P>
The <B>pkg-config</B> program makes finding the correct compiler flag values and
library location far easier.
During the installation of libsndfile, a file named <B>sndfile.pc</B> is installed
in the directory <B>${libdir}/pkgconfig</B> (ie if libsndfile is installed in
<B>/usr/local/lib</B>, <B>sndfile.pc</B> will be installed in
<B>/usr/local/lib/pkgconfig/</B>).
</P>
<P>
In order for pkg-config to find sndfile.pc it may be necessary to point the
environment variable <B>PKG_CONFIG_PATH</B> in the right direction.
</P>
<PRE>
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
</PRE>
<P>
Then, to compile a C file into an object file, the command would be:
</P>
<PRE>
gcc `pkg-config --cflags sndfile` -c somefile.c
</PRE>
<P>
and to link a number of objects into an executable that links against libsndfile,
the command would be:
</P>
<PRE>
gcc `pkg-config --libs sndfile` obj1.o obj2.o -o program
</PRE>

<A NAME="Q009"></A>
<H2><BR/><B>Q9 : How about adding the ability to write/read sound files to/from
memory buffers?</B></H2>
<P>
This has been added for version 1.0.13.
</P>
<!-- ========================================================================= -->
<A NAME="Q010"></A>
<H2><BR/><B>Q10 : Reading a 16 bit PCM file as normalised floats and then
writing them back changes some sample values. Why?</B></H2>
<P>
This is caused by the fact that the conversion from 16 bit short to float is
done by dividing by 32768 (0x8000 in hexadecimal) while the conversion from
float to 16 bit short is done by multiplying by 32767 (0x7FFF in hex).
So for instance, a value in a 16 bit PCM file of 20000 gets read as a floating
point number of 0.6103515625 (20000.0 / 0x8000).
Converting that back to a 16 bit short results in a value of 19999.3896484375
(0.6103515625 * 0x7FFF) which then gets rounded down to 19999.
</P>
<P>
You will notice that for this particular case, the error is 1 in 20000 or
0.005%.
Interestingly, for values of less than 16369, dividing by 0x8000 followed
by multiplying by 0x7FFF and then rounding the result, gives back the
original value.
It turns out that as long as the host operating system supplies the 1999 ISO
C Standard functions <B>lrintf</B> and <B>lrint</B> (or a replacement has
been supplied) then the maximum possible error is 1 in 16369 or about 0.006%.
</P>
<P>
Regardless of the size of the error, the reason why this is done is rather
subtle.
</P>
<P>
In a file containing 16 bit PCM samples, the values are restricted to the range
[-32768, 32767] while we want floating point values in the range [-1.0, 1.0].
The only way to do this conversion is to do a floating point division by a value
of 0x8000.
Converting the other way, the only way to ensure that floating point values in
the range [-1.0, 1.0] are within the valid range allowed by a 16 bit short is
to multiply by 0x7FFF.
</P>
<P>
Some people would say that this is a severe short-coming of libsndfile.
I would counter that anybody who is constantly converting back and forth
between 16 bit shorts and normalised floats is going to suffer other losses
in audio quality that they should also be concerned about.
</P>
<P>
Since this problem only occurs when converting between integer data on disk and
normalized floats in the application, it can be avoided by using something
other than normalized floats in the application.
Alternatives to normalized floats are the <b>short</b> and <b>int</b> data
types (ie using sf_read_short or sf_read_int) or using un-normalized floats
(see
<a href="command.html#SFC_SET_NORM_FLOAT">
SFC_SET_NORM_FLOAT</a>).
</P>
<P>
Another way to deal with this problem is to consider 16 bit short data as a
final destination format only, not as an intermediate storage format.
All intermediate data (ie which is going to be processed further) should be
stored in floating point format which is supported by all of the most common
file formats.
If floating point files are considered too large (2 times the size of a 16 bit
PCM file), it would also be possible to use 24 bit PCM as an intermediate
storage format (and which is also supported by most common file types).
</P>

<A NAME="Q011"></A>
<H2><BR/><B>Q11 : I'm having problems with u-law encoded WAV files generated by
libsndfile in Winamp. Why?
</B></H2>
<P>
This is actually a Winamp problem.
The official Microsoft spec suggests that the 'fmt ' chunk should be 18 bytes.
Unfortunately at least one of Microsoft's own applications (Sound Recorder on
Win98 I believe) did not accept 18 bytes 'fmt ' chunks.
</P>
<P>
Michael Lee did some experimenting and found that:
</P>
<PRE>
I have checked that Windows Media Player 9, QuickTime Player 6.4,
RealOne Player 2.0 and GoldWave 5.06 can all play u-law files with
16-byte or 18-byte 'fmt ' chunk. Only Winamp (2.91) and foobar2000
are unable to play u-law files with 16-byte 'fmt ' chunk.

Even this is a very small sampling of all the players out there.
For that reason it is probably not a good idea to change this now because there

<A NAME="Q012"></A>
<H2><BR/><B>Q12 : I'm looking at sf_read*. What are items? What are frames?
</B></H2>
<P>
An <tt>item</tt> is a single sample of the data type you are reading; ie a
single <tt>short</tt> value for <tt>sf_read_short</tt> or a single <tt>float</tt>
for <tt>sf_read_float</tt>.
</P>
<P>
For a sound file with only one channel, a frame is the same as a item (ie a
single sample) while for multi channel sound files, a single frame contains a
single item for each channel.
</P>
<P>
Here are two simple, correct examples, both of which are assumed to be working
on a stereo file, first using items:
</P>
<PRE>
#define CHANNELS 2
short data [CHANNELS * 100] ;
sf_count items_read = sf_read_short (file, data, 200) ;
assert (items_read == 200) ;
</PRE>
<P>
and now readng the exact same amount of data using frames:
</P>
<PRE>
#define CHANNELS 2
short data [CHANNELS * 100] ;
sf_count frames_read = sf_readf_short (file, data, 100) ;
assert (frames_read == 100) ;

<A NAME="Q013"></A>
<H2><BR/><B>Q13 : Why can't libsndfile open this Sound Designer II (SD2) file?
</B></H2>
<P>
This is somewhat complicated.
First some background.
</P>
<P>
SD2 files are native to the Apple Macintosh platform and use features of
the Mac filesystem (file resource forks) to store the file's sample rate,
number of channels, sample width and more.
When you look at a file and its resource fork on Mac OS X it looks like
this:
</P>
<PRE>
-rw-r--r-- 1 erikd erikd 46512 Oct 18 22:57 file.sd2
-rw-r--r-- 1 erikd erikd 538 Oct 18 22:57 file.sd2/rsrc
</PRE>
<P>
Notice how the file itself looks like a directory containing a single file
named <B>rsrc</B>.
When libsndfile is compiled for MacOS X, it should open (for write and read)
SD2 file with resource forks like this without any problems.
It will also handle files with the resource fork in a separate file as
described below.
</P>
<P>
When SD2 files are moved to other platforms, the resource fork of the file
can sometimes be dropped altogether.
All that remains is the raw audio data and no information about the number
of channels, sample rate or bit width which makes it a little difficult for
libsndfile to open the file.
</P>
<P>
However, it is possible to safely move an SD2 file to a Linux or Windows
machine.
For instance, when an SD2 file is copied from inside MacOS X to a windows
shared directory or a Samba share (ie Linux), MacOS X is clever enough to
store the resource fork of the file in a separate hidden file in the
same directory like this:
</P>
<PRE>
-rw-r--r-- 1 erikd erikd 538 Oct 18 22:57 ._file.sd2
-rw-r--r-- 1 erikd erikd 46512 Oct 18 22:57 file.sd2
</PRE>
<P>
Regardless of what platform it is running on, when libsndfile is asked to
open a file named <B>"foo"</B> and it can't recognize the file type from
the data in the file, it will attempt to open the resource fork and if
that fails, it then tries to open a file named <B>"._foo"</B> to see if
the file has a valid resource fork.
This is the same regardless of whether the file is being opened for read
or write.
</P>
<P>
In short, libsndfile should open SD2 files with a valid resource fork on
all of the platforms that libsndfile supports.
If a file has lost its resource fork, the only option is the open the file
using the SF_FORMAT_RAW option and guessing its sample rate, channel count
and bit width.
</P>
<P>
Occasionally, when SD2 files are moved to other systems, the file is
<A HREF="http://www.macdisk.com/binhexen.php3">BinHexed</A>
which wraps the resource fork and the data fork together.
For these files, it would be possible to write a BinHex parser but
there is not a lot to gain considering how rare these BinHexed SD2
files are.
</P>

<A NAME="Q014"></A>
<H2><BR/><B>Q14 : I'd like to statically link libsndfile to my closed source
application. Can I buy a license so that this is possible?
</B></H2>
<P>
Unfortunately no.
libsndfile contains code written by other people who have agreed that their
code be used under the GNU LGPL but no more.
Even if they were to agree, there would be significant difficulties in
dividing up the payments fairly.
</P>
<P>
The <B>only</B> way you can legally use libsndfile as a statically linked
library is if your application is released under the GNU GPL or LGPL.

<A NAME="Q015"></A>
<H2><BR/><B>Q15 : My program is crashing during a call to a function in libsndfile.
Is this a bug in libsndfile?
</B></H2>
<P>
libsndfile is being used by large numbers of people all over the world
without any problems like this. That means that it is much more likely
that your code has a bug than libsndfile. However, it is still possible
that there is a bug in libsndfile.
</P>
<P>
To figure out whether it is your code or libsndfile you should do the
following:
</P>
<UL>
<LI>Make sure you are compiling your code with warnings switched on and
that you fix as many warnings as possible.
With the GNU compiler (gcc) I would recommend at least
<B>-W -Wall -Werror</B> which will force you to fix all warnings
before you can run the code.
<LI>Try using a memory debugger.
<A HREF="http://valgrind.kde.org/">Valgrind</A> on x86 Linux is excellent.
<A HREF="http://www.ibm.com/software/awdtools/purify/">Purify</A> also
has a good reputation.
<LI>If the code is clean after the above two steps and you still get
a crash in libsndfile, then send me a small snippet of code (no
more than 30-40 lines) which includes the call to sf_open() and
also shows how all variables passed to/returned from sf_open()
are defined.
</UL>
<!-- ========================================================================= -->
<A NAME="Q016"></A>
<H2><BR/><B>Q16 : Will you accept a fix for compiling libsndfile with compiler X?
</B></H2>
<P>
If compiler X is a C++ compiler then no.
C and C++ are different enough to make writing code that compiles as valid C
and valid C++ too difficult.
I would rather spend my time fixing bugs and adding features.
</P>
<P>
If compiler X is a C compiler then I will do what I can as long as that does
not hamper the correctness, portability and maintainability of the existing
code.
It should be noted however that libsndfile uses features specified by the 1999
ISO C Standard.
This can make compiling libsndfile with some older compilers difficult.
</P>
<!-- ========================================================================= -->
<A NAME="Q017"></A>
<H2><BR/><B>Q17 : Can libsndfile read/write files from/to UNIX pipes?
</B></H2>
<P>
Yes, libsndfile can read files from pipes.
Unfortunately, the write case is much more complicated.
</P>
<P>
File formats like AIFF and WAV have information at the start of the file (the
file header) which states the length of the file, the number of sample frames
etc.
This information must be filled in correctly when the file header is written,
but this information is not reliably known until the file is closed.
This means that libsndfile cannot write AIFF, WAV and many other file types
to a pipe.
</P>
<P>
However, there is at least one file format (AU) which is specifically designed
to be written to a pipe.
Like AIFF and WAV, AU has a header with a sample frames field, but it is
specifically allowable to set that frames field to 0x7FFFFFFF if the file
length is not known when the header is written.
The AU file format can also hold data in many of the standard formats (ie
SF_FORMAT_PCM_16, SF_FORMAT_PCM_24, SF_FORMAT_FLOAT etc) as well as allowing
data in both big and little endian format.

<!-- ========================================================================= -->
<A NAME="Q018"></A>
<H2><BR/><B>Q18 : Is it possible to build a Universal Binary on Mac OS X?
</B></H2>
<P>
Yes, but you must do two separate configure/build/test runs; one on PowerPC
and one on Intel.
It is then possible to merge the binaries into a single universal binary using
one of the programs in the Apple tool chain.
</P>
<P>
It is <b>not</b> possible to build a working universal binary via a single
compile/build run on a single CPU.
</P>
<P>
The problem is that the libsndfile build process detects features of the CPU its
being built for during the configure process and when building a universal binary,
configure is only run once and that data is then used for both CPUs.
That configure data will be wrong for one of those CPUs.
You will still be able to compile libsndfile, and the test suite will pass on
the machine you compiled it on.
However, if you take the universal binary test suite programs compiled on one
CPU and run them on the other, the test suite will fail.
</P>
<P>
Part of the problem is the the CPU endian-ness is detected at configure time.
Yes, I know the Apple compiler defines one of the macros __LITTLE_ENDIAN__
and __BIG_ENDIAN__, but those macros are not part of the 1999 ISO C Standard
and they are not portable.
</P>
<P>
Endian issues are not the only reason why the cross compiled binary will fail.
The configure script also detects other CPU specific idiosyncrasies to provide
more optimized code.
</P>
<P>
Finally, the real show stopper problem with universal binaries is the problem
with the test suite.
libsndfile contains a huge, comprehensive test suite.
When you compile a universal binary and run the test suite, you only test the
native compile.
The cross compiled binary (the one with the much higher chance of having
problems) cannot be tested.
</P>
<P>
Now, if you have read this far you're probably thinking there must be a way
to fix this and there probably is.
The problem is that its a hell of a lot of work and would require significant
changes to the configure process, the internal code and the test suite.
In addition, these changes must not break compilation on any of the platforms
libsndfile is currently working on.
</p>
<!-- ========================================================================= -->
<A NAME="Q019"></A>
<H2><BR/><B>Q19 : I have project files for Visual Studio / XCode / Whatever. Why
don't you distribute them with libsndfile?
</B></H2>
<P>
There's a very good reason for this.
I will only distribute things that I actually have an ability to test and
maintain.
Project files for a bunch of different compilers and Integrated Development
Environments are simply too difficult to maintain.
</P>
<P>
The problem is that every time I add a new file to libsndfile or rename an
existing file I would have to modify all the project files and then test that
libsndfile still built with all the different compilers.
</P>
<P>
Maintaining these project files is also rather difficult if I don't have access
to the required compiler/IDE.
If I just edit the project files without testing them I will almost certainly
get it wrong.
If I release a version of libsndfile with broken project files, I'll get a bunch
of emails from people complaining about it not building and have no way of
fixing or even testing it.
</P>
<P>
I currently release sources that I personally test on Win32, Linux and
MacOS X (PowerPC) using the compiler I trust (GNU GCC).
Supporting one compiler on three (actually much more because GCC is available
almost everywhere) platforms is doable without too much pain.
I also release binaries for Win32 with instructions on how to use those
binaries with Visual Studio.
As a guy who is mainly interested in Linux, I'm not to keen to jump through
a bunch of hoops to support compilers and operating systems I don't use.
</P>
<P>
So, I hear you want to volunteer to maintain the project files for Some Crappy
Compiler 2007?
Well sorry, that won't work either.
I have had numerous people over the years offer to maintaining the project
files for Microsoft's Visual Studio.
Every single time that happened, they maintained it for a release or two and
then disappeared off the face of the earth.
Hence, I'm not willing to enter into an arrangement like that again.

<A NAME="Q020"></A>
<H2><BR/><B>Q20 : Why doesn't libsndfile support MP3? Lots of other Open Source
projects support it!
</B></H2>
<P>
MP3 is not supported for one very good reason; doing so requires the payment
of licensing fees.
As can be seen from
<a href="http://www.mp3licensing.com/royalty/software.html">
mp3licensing.com</a>
the required royalty payments are not cheap.
</P>
<p>
Yes, I know other libraries ignore the licensing requirements, but their legal
status is extremely dubious.
At any time, the body selling the licenses could go after the authors of those
libraries.
Some of those authors may be students and hence wouldn't be worth pursuing.
</P>
<p>
However, libsndfile is released under the name of a company, Mega Nerd Pty Ltd;
a company which has income from from libsamplerate licensing, libsndfile based
consulting income and other unrelated consulting income.
Adding MP3 support to libsndfile could place that income under legal threat.
</p>
<p>
Fortunately, Ogg Vorbis exists as an alternative to MP3.
Support for Ogg Vorbis was added to libsndfile (mostly due to the efforts of
John ffitch of the Csound project) in version 1.0.18.

<H2><BR/><B>Q21 : How do I use libsndfile in a closed source or commercial program
and comply with the license?
</B></H2>
<p>
Here is a checklist of things you need to do to make sure your use of libsndfile
in a closed source or commercial project complies with the license libsndfile is
released under, the GNU Lesser General Public License (LGPL):
</p>
<ul>
<li>Make sure you are linking to libsndfile as a shared library (Linux and Unix
systems), Dynamic Link Library (Microsoft Windows) or dynlib (Mac OS X).
If you are using some other operating system that doesn't allow dynamically
linked libraries, you will not be able to use libsndfile unless you release
the source code to your program.
<li>In the licensing documentation for your program, add a statement that your
software depends on libsndfile and that libsndfile is released under the GNU
Lesser General Public License, either
<a href="http://www.gnu.org/licenses/lgpl-2.1.txt">version 2.1</a>
or optionally
<a href="http://www.gnu.org/licenses/lgpl.txt">version 3</a>.
<li>Include the text for both versions of the license, possibly as separate
files named libsndfile_lgpl_v2_1.txt and libsndfile_lgpl_v3.txt.
</ul>

<A NAME="Q022"></A>
<H2><BR/><B>Q22 : What versions of Windows does libsndfile work on?
</B></H2>
<p>
Currently the precompiled windows binaries are thoroughly tested on Windows XP.
As such, they should also work on Win2k and Windows Vista.
They may also work on earlier versions of Windows.
</p>
<p>
Since version 0.1.18 I have also been releasing precompiled binaries for Win64,
the 64 bit version of Windows.
These binaries have received much less testing than the 32 bit versions, but
should work as expected.
I'd be very interested in receiving feedback on these binaries.
</p>

<A NAME="Q023"></A>
<H2><BR/><B>Q23 : I'm cross compiling libsndfile for another platform. How can I
run the test suite?
</B></H2>
<p>
</p>
<p>
Since version 1.0.21 the top level Makefile has an extra make target,
'test-tarball'.
Building this target creates a tarball called called:
</p>
<center><tt>
libsndfile-testsuite-${host_triplet}-${version}.tar.gz
</tt></center>
<p>
in the top level directory.
This tarball can then be copied to the target platform.
Once untarred and test script <tt>test_wrapper.sh</tt> can be run from
the top level of the extracted tarball.

Libsndfile is a library designed to allow the reading and writing of many
different sampled sound file formats (such as MS Windows WAV and the Apple/SGI
AIFF format) through one standard library interface.
</P>
<!-- pepper -->
<P>
During read and write operations, formats are seamlessly converted between the
format the application program has requested or supplied and the file's data
format. The application programmer can remain blissfully unaware of issues
such as file endian-ness and data format. See <A HREF="#note1">Note 1</A> and
<A HREF="#note2">Note 2</A>.

Every effort is made to keep these documents up-to-date, error free and

<h3><b>Virtual File Open Function</b></h3>
<pre>
SNDFILE* sf_open_virtual (SF_VIRTUAL_IO *sfvirtual, int mode, SF_INFO *sfinfo, void *user_data) ;
</pre>
<p>
Opens a soundfile from a virtual file I/O context which is provided
by the caller. This is usually used to interface libsndfile to a stream or buffer
based system. Apart from the sfvirtual and the user_data parameters this function behaves
like <a href="#open">sf_open</a>.
</p>
<pre>
typedef struct
{ sf_vio_get_filelen get_filelen ;
sf_vio_seek seek ;
sf_vio_read read ;
sf_vio_write write ;
sf_vio_tell tell ;
} SF_VIRTUAL_IO ;
</pre>
<p>
Libsndfile calls the callbacks provided by the SF_VIRTUAL_IO structure when opening, reading
and writing to the virtual file context. The user_data pointer is a user defined context which
will be available in the callbacks.
</p>
<pre>
typedef sf_count_t (*sf_vio_get_filelen) (void *user_data) ;
typedef sf_count_t (*sf_vio_seek) (sf_count_t offset, int whence, void *user_data) ;
typedef sf_count_t (*sf_vio_read) (void *ptr, sf_count_t count, void *user_data) ;
typedef sf_count_t (*sf_vio_write) (const void *ptr, sf_count_t count, void *user_data) ;
typedef sf_count_t (*sf_vio_tell) (void *user_data) ;
</pre>
<h4>sf_vio_get_filelen</h4>
<pre>
typedef sf_count_t (*sf_vio_get_filelen) (void *user_data) ;
</pre>
<p>
The virtual file contex must return the length of the virtual file in bytes.<br>
</p>
<h4>sf_vio_seek</h4>
<pre>
typedef sf_count_t (*sf_vio_seek) (sf_count_t offset, int whence, void *user_data) ;
</pre>
<p>
The virtual file context must seek to offset using the seek mode provided by whence which is one of<br>
</p>
<pre>
SEEK_CUR
SEEK_SET
SEEK_END
</pre>
<p>
The return value must contain the new offset in the file.
</p>
<h4>sf_vio_read</h4>
<pre>
typedef sf_count_t (*sf_vio_read) (void *ptr, sf_count_t count, void *user_data) ;
</pre>
<p>
The virtual file context must copy ("read") "count" bytes into the
buffer provided by ptr and return the count of actually copied bytes.
</p>
<h4>sf_vio_write</h4>
<pre>
typedef sf_count_t (*sf_vio_write) (const void *ptr, sf_count_t count, void *user_data) ;
</pre>
<p>
The virtual file context must process "count" bytes stored in the
buffer passed with ptr and return the count of actually processed bytes.<br>
</p>
<h4>sf_vio_tell</h4>
<pre>
typedef sf_count_t (*sf_vio_tell) (void *user_data) ;
</pre>
<p>
Return the current position of the virtual file context.<br>
</p>
<A NAME="check"></A>
<BR><H2><B>Format Check Function</B></H2>
<PRE>
int sf_format_check (const SF_INFO *info) ;
</PRE>
<!-- pepper -->
<P>
This function allows the caller to check if a set of parameters in the SF_INFO struct
is valid before calling sf_open (SFM_WRITE).
</P>
<P>
sf_format_check returns TRUE if the parameters are valid and FALSE otherwise.
</P>
<A NAME="seek"></A>
<BR><H2><B>File Seek Functions</B></H2>
<PRE>
sf_count_t sf_seek (SNDFILE *sndfile, sf_count_t frames, int whence) ;
</PRE>
<P>
The file seek functions work much like lseek in unistd.h with the exception that
the non-audio data is ignored and the seek only moves within the audio data section of
the file.
In addition, seeks are defined in number of (multichannel) frames.
Therefore, a seek in a stereo file from the current position forward with an offset
of 1 would skip forward by one sample of both channels.
</P>
<P>
like lseek(), the whence parameter can be any one of the following three values:
</P>
<PRE>
SEEK_SET - The offset is set to the start of the audio data plus offset (multichannel) frames.
SEEK_CUR - The offset is set to its current location plus offset (multichannel) frames.
SEEK_END - The offset is set to the end of the data plus offset (multichannel) frames.
</PRE>
<!-- pepper -->
<P>
Internally, libsndfile keeps track of the read and write locations using separate
read and write pointers.
If a file has been opened with a mode of SFM_RDWR, bitwise OR-ing the standard whence
values above with either SFM_READ or SFM_WRITE allows the read and write pointers to
be modified separately.
If the SEEK_* values are used on their own, the read and write pointers are
both modified.
</P>
<P>
Note that the frames offset can be negative and in fact should be when SEEK_END is used for the
whence parameter.
</P>
<P>
sf_seek will return the offset in (multichannel) frames from the start of the audio data
or -1 if an error occured (ie an attempt is made to seek beyond the start or end of the file).
</P>
<A NAME="error"></A>
<H2><BR><B>Error Reporting Functions</B></H2>
<PRE>
int sf_error (SNDFILE *sndfile) ;
</PRE>
<P>
This function returns the current error number for the given SNDFILE.
The error number may be one of the following:
</P>
<PRE>
enum
{ SF_ERR_NO_ERROR = 0,
SF_ERR_UNRECOGNISED_FORMAT = 1,
SF_ERR_SYSTEM = 2,
SF_ERR_MALFORMED_FILE = 3,

} ;
</PRE>
<!-- pepper -->
<P>
or any one of many other internal error values.
Applications should only test the return value against error values defined in
&lt;sndfile.h&gt; as the internal error values are subject to change at any
time.
For errors not in the above list, the function sf_error_number() can be used to
convert it to an error string.
</P>
<PRE>
const char* sf_strerror (SNDFILE *sndfile) ;
const char* sf_error_number (int errnum) ;
</PRE>
<P>
The error functions sf_strerror() and sf_error_number() convert the library's internal
error enumerations into text strings.
</P>
<PRE>
int sf_perror (SNDFILE *sndfile) ;
int sf_error_str (SNDFILE *sndfile, char* str, size_t len) ;
</PRE>
<P>
The functions sf_perror() and sf_error_str() are deprecated and will be dropped
from the library at some later date.

<A NAME="close"></A>
<H2><BR><B>File Close Function</B></H2>
<PRE>

It is important to note that the data type used by the calling program and the data

The sf_read_XXXX functions return the number of items read.
Unless the end of the file was reached during the read, the return value should

<H2><BR><B>Note 1</B></H2>
<!-- pepper -->
<P>
When converting between integer PCM formats of differing size (ie using sf_read_int()
to read a 16 bit PCM encoded WAV file) libsndfile obeys one simple rule:
</P>
<P CLASS=indent_block>
Whenever integer data is moved from one sized container to another sized container,
the most significant bit in the source container will become the most significant bit
in the destination container.
</P>
<P>
When converting between integer data and floating point data, different rules apply.
The default behaviour when reading floating point data (sf_read_float() or
sf_read_double ()) from a file with integer data is normalisation. Regardless of
whether data in the file is 8, 16, 24 or 32 bit wide, the data will be read as
floating point data in the range [-1.0, 1.0]. Similarly, data in the range [-1.0, 1.0]
will be written to an integer PCM file so that a data value of 1.0 will be the largest
allowable integer for the given bit width. This normalisation can be turned on or off
using the <A HREF="command.html">sf_command</A> interface.
</P>
<A NAME="note2"></A>
<H2><BR><B>Note 2</B></H2>
<P>
Reading a file containg floating point data (allowable with WAV, AIFF, AU and other
file formats) using integer read methods (sf_read_short() or sf_read_int()) can
produce unexpected results.
For instance the data in the file may have a maximum absolute value &lt; 1.0 which
would mean that all sample values read from the file will be zero.
In order to read these files correctly using integer read methods, it is recommended
that you use the
<A HREF="command.html">sf_command</A>
interface, a command of
<A HREF="command.html#SFC_SET_SCALE_FLOAT_INT_READ">SFC_SET_SCALE_FLOAT_INT_READ</A>
and a parameter of SF_TRUE to force correct scaling.

<P>
Before even attempting to report a bug in libsndfile please make sure you have
read the
<A HREF="FAQ.html">Frequently Asked Questions</A>.
If you are having a problem writing code using libsndfile make sure you read
the
<A HREF="api.html">Application Programming Interface</A>
documentation.
</P>
<P>
That said, I am interested in finding and fixing all genuine bugs in libsndfile.
Bugs I want to fix include any of the following problems (and probably others) :
</P>
<UL>
<LI> Compilation problems on new platforms.
<LI> Errors being detected during the `make check' process.
<LI> Segmentation faults occuring inside libsndfile.
<LI> libsndfile hanging when opening a file.
<LI> Supported sound file types being incorrectly read or written.
<LI> Omissions, errors or spelling mistakes in the documentation.
</UL>
<P>
When submitting a bug report you must include :
</P>
<UL>
<LI> Your system (CPU and memory size should be enough).
<LI> The operating system you are using.
<LI> Whether you are using a package provided by your distribution or you
compiled it youself.
<LI> If you compiled it yourself, the compiler you are using. (Also make
sure to run 'make check'.)
<LI> A description of the problem.
<LI> Information generated by the sndfile-info program (see next paragraph).
<LI> If you are having problems with sndfile-play and ALSA on Linux, I will
need information about your kernel, ALSA version, compiler version,
whether you compiled the kernel/ALSA your self or installed from a
package etc.
</UL>
<P>
If libsndfile compiles and installs correctly but has difficulty reading a particular
file or type of file you should run the <B>sndfile-info</B> program (from the examples
directory of the libsndfile distribution) on the file. See
<A HREF="sndfile_info.html">here</A>
for an example of the use of the <B>sndfile-info</B> program.
</P>
<P>
Please do not send me a sound file which fails to open under libsndfile unless I
specifically ask you to. The above information should usually suffice for most
problems.
</P>
<P>
Once you have the above information you should submit a ticket on the libsnfile
<A HREF="https://github.com/erikd/libsndfile/issues">github issue tracker</A>.

<p>
Dear libsndfile user,
</p>
<!-- pepper -->
<p>
This library was developed on Linux for Linux. I am not a Windows user and
maintaining this library for Windows costs me significant amounts of time above
and beyond the time taken to make it work on Linux and Unix-like systems.
</p>
<!-- pepper -->
<p>
I therefore ask Windows users of libsndfile to donate to ensure that libsndfile's
support for Windows continues. As long as donations continue to flow in at a decent
rate, I will continue to release precompiled Windows binaries in sync with the
Linux/Unix version. If donations are poor, support for windows will fall behind.
</p>
<!-- pepper -->
<p>
You are free to donate any amount you chose.
As a guideline:
</p>
<!-- pepper -->
<ul>
<li>If you are simply a user of libsndfile that would like to ensure that
the development of libsndfile continues, a donation of $10US would be more
than adequate.
</li>
<li>If you are shareware author that distributes libsndfile with your app and
makes more than $1000 a year from your shareware, a one off donation of $50
would be appropriate.
</li>
<li>If your company is a commercial software house that distributes one or more
products that ship with libsndfile, a donation of $100 every second or third
year would be appropriate.
</li>
</ul>
<!-- pepper -->
<p>
Donations can be made in Bitcoin to the Bitcoin address
<b>15hVWemFiH6DLJ22SBYPk9b4fgWtxBEvfQ</b>
which can be verified by checking the following GPG signature.

<P>
By using the open SNDFILE with a file descriptor function:
</P>
<!-- pepper -->
<PRE>
SNDFILE* sf_open_fd (int fd, int mode, SF_INFO *sfinfo, int close_desc) ;
</PRE>
<!-- pepper -->
<P>
it is possible to open sound files embedded within larger files.
There are however a couple of caveats:
<P>
<!-- pepper -->
<UL>
<LI> Read/Write mode (SFM_RDWR) is not supported.
<LI> Writing of embedded files is only supported at the end of the file.
<LI> Reading of embedded files is only supported at file offsets greater
than zero.
<LI> Not all file formats are supported (currently only WAV, AIFF and AU).
</UL>
<!-- pepper -->
<P>
The test program <B>multi_file_test.c</B> in the <B>tests/</B> directory of the
source code tarball shows how this functionality is used to read and write
embedded files.

<P>
Libsndfile is a C library for reading and writing files containing sampled sound
(such as MS Windows WAV and the Apple/SGI AIFF format) through one standard
library interface. It is released in source code format under the
<A HREF="http://www.gnu.org/copyleft/lesser.html">Gnu Lesser General Public License</A>.
</P>
<!-- pepper -->
<P>
The library was written to compile and run on a Linux system but should compile
and run on just about any Unix (including MacOS X).
There are also pre-compiled binaries available for 32 and 64 bit windows.
</P>
<P>
It was designed to handle both little-endian (such as WAV) and big-endian
(such as AIFF) data, and to compile and run correctly on little-endian (such as Intel
and DEC/Compaq Alpha) processor systems as well as big-endian processor systems such
as Motorola 68k, Power PC, MIPS and Sparc.
Hopefully the design of the library will also make it easy to extend for reading and
writing new sound file formats.
</P>
<!-- pepper -->
<P>
It has been compiled and tested (at one time or another) on the following systems:
</P>
<!-- pepper -->
<UL>
<LI>Every platform supported by Debian GNU/Linux including x86_64-linux-gnu,
i486-linux-gnu, powerpc-linux-gnu, sparc-linux-gnu, alpha-linux-gnu,
mips-linux-gnu and armel-linux-gnu.</LI>
<LI>powerpc-apple-darwin7.0 (Mac OS X 10.3)</LI>
<LI>sparc-sun-solaris2.8 (using gcc)</LI>
<LI>mips-sgi-irix5.3 (using gcc)</LI>
<LI>QNX 6.0</LI>
<LI>i386-unknown-openbsd2.9</LI>
</UL>
<!-- pepper -->
<P>
At the moment, each new release is being tested on i386 Linux, x86_64 Linux,
PowerPC Linux, Win32 and Win64.
</P>
<!-- pepper -->
<A NAME="Capabilities"></A>
<A NAME="Features"></A>
<H1><B>Features</B></H1>
<P>
libsndfile has the following main features :
</P>
<UL>
<lI> Ability to read and write a large number of file formats.
<LI> A simple, elegant and easy to use Applications Programming Interface.
<LI> Usable on Unix, Win32, MacOS and others.
<LI> On the fly format conversion, including endian-ness swapping, type conversion
and bitwidth scaling.
<LI> Optional normalisation when reading floating point data from files containing
integer data.
<LI> Ability to open files in read/write mode.
<LI> The ability to write the file header without closing the file (only on files
open for write or read/write).
<LI> Ability to query the library about all supported formats and retrieve text
strings describing each format.
</UL>
<P>
libsndfile has a comprehensive test suite so that each release is as bug free
as possible.
When new bugs are found, new tests are added to the test suite to ensure that
these bugs don't creep back into the code.
When new features are added, tests are added to the test suite to make sure that
these features continue to work correctly even when they are old features.
</P>
<P>
The following table lists the file formats and encodings that libsndfile can read
and write.
The file formats are arranged across the top and encodings along the left
edge.

From version 1.0.18, libsndfile also reads and writes
<a href="http://flac.sourceforge.net/">FLAC</a>
and
<a href="http://www.vorbis.com/">Ogg/Vorbis</a>.

<!-- pepper -->
<P>
Some of the file formats I am also interested in adding are:
</P>
<UL>
<LI> Kurzweil K2000 sampler files.
<LI> Ogg Speex.
</UL>
<P>
I have decided that I will not be adding support for MPEG Layer 3 (commonly
known as MP3) due to the patent issues surrounding this file format.
See
<a href="FAQ.html#Q020">
the FAQ</a>
for more.
</P>
<P>
Other file formats may also be added on request.

<A NAME="History"></A>
<H1><B>History</B></H1>
<P>
My first attempt at reading and writing WAV files was in 1990 or so under Windows
3.1.
I started using Linux in early 1995 and contributed some code to the
<A HREF="http://www.vaxxine.com/ve3wwg/gnuwave.html">wavplay</A>
program.
That contributed code would eventually mutate into this library.
As one of my interests is Digital Signal Processing (DSP) I decided that as well as
reading data from an audio file in the native format (typically 16 bit short integers)
it would also be useful to be able to have the library do the conversion to floating
point numbers for DSP applications.
It then dawned on me that whatever file format (anything from 8 bit unsigned chars,
to 32 bit floating point numbers) the library should be able to convert the data to
whatever format the library user wishes to use it in.
For example, in a sound playback program, the library caller typically wants the sound
data in 16 bit short integers to dump into a sound card even though the data in the
file may be 32 bit floating point numbers (ie Microsoft's WAVE_FORMAT_IEEE_FLOAT
format).
Another example would be someone doing speech recognition research who has recorded
some speech as a 16 bit WAV file but wants to process it as double precision floating
point numbers.

Subject: Can you help with a problem?
Date: Tue, 20 Jul 2004 22:49:21 +0100
Hi,
I'm trying to get the source examples in the "Programming Linux Games"
(NoStarch, Loki Software + John R. Hall) which use sndfile.h/libsndfile.
While I can guess some of the newer versions of function calls and
enumerations, there are some which I cannot guess.
Would you be able to translate them to the current version of
enumeration and function calls so that I can update the source?
These are the three currently failing me:
sf_open_read(filename, SF_INFO *sfinfo) (guess: sf_open(filename,SFM_READ, &sfinfo))
SF_FORMAT_PCM (guess: either SF_FORMAT_PCM_U8 or _RAW)
SF_INFO.pcmbitwidth (guess: no idea!)
There are probably more. I'm happy to send you the source files for
sound calls, scan the pages or anything else. Failing that, is there
somewhere with the changes listed so I can try and fix the code for myself?
Thanks
TTFN
Paul

yes.

Actually this list:
SF_FORMAT_PCM_U8
SF_FORMAT_PCM_S8
SF_FORMAT_PCM_16
SF_FORMAT_PCM_24
SF_FORMAT_PCM_32
> SF_INFO.pcmbitwidth (guess: no idea!)
WIth the above change, pcmbitwidth becomes redundant.

Version 1.0.0 came out some time ago, but I think this:
http://www.mega-nerd.com/libsndfile/version-1.html
lists most of the changes. You should also look at the API docs:

I know, but the source code explicitly has SF_FORMAT_PCM which given the
code afterwards would equate to one of the above, but given that PCM
files can have a varied bitwidth the author probably wanted to cover all
bases.

But surely the existing code does something like:
sfinfo.format = SF_FORMAT_WAV | SF_FORMAT_PCM;
sfinfo.pcmbitwidth = 16;
which can be directly translated to:
sfinfo.format = SF_FORMAT_WAV | SF_FORMAT_PCM_16;
and the same for pcmbitwitdhs of 24 and 32. For pcmbitwidth of 8
you need to know that WAV files use SF_FORMAT_PCM_U8 and AIFF
files use SF_FORMAT_PCM_S8. Thats all there is to it.

If only!
The actual code is this
int LoadSoundFile(char *filename, sound_p sound)
{
SNDFILE *file;
SF_INFO file_info;
short *buffer_short = NULL;
u_int8_t *buffer_8 = NULL;
int16_t *buffer_16 = NULL;
unsigned int i;
/* Open the file and retrieve sample information. */

/* Make sure the format is acceptable. */
if ((file_info.format & 0x0F) != SF_FORMAT_PCM) {
printf("'%s' is not a PCM-based audio file.\n", filename);
sf_close(file);
return -1;
}
if ((file_info.pcmbitwidth == 8) && (file_info.channels == 1)) {
sound->format = AL_FORMAT_MONO8;
} else if ((file_info.pcmbitwidth == 8) && (file_info.channels == 2)) {
sound->format = AL_FORMAT_STEREO8;
} else if ((file_info.pcmbitwidth == 16) && (file_info.channels == 1)) {
sound->format = AL_FORMAT_MONO16;
} else if ((file_info.pcmbitwidth == 16) && (file_info.channels == 2)) {
sound->format = AL_FORMAT_STEREO16;
} else {
printf("Unknown sample format in %s.\n", filename);
sf_close(file);
return -1;
}
/* Allocate buffers. */
buffer_short = (short *)malloc(file_info.samples * file_info.channels * sizeof (short));
buffer_8 = (u_int8_t *)malloc(file_info.samples * file_info.channels * file_info.pcmbitwidth / 8);
buffer_16 = (int16_t *)buffer_8;
if (buffer_short == NULL || buffer_8 == NULL) {
printf("Unable to allocate enough memory for '%s'.\n", filename);
goto error_cleanup;
}
/* Read the entire sound file. */
if (sf_readf_short(file,buffer_short,file_info.samples) == (size_t)-1) {
printf("Error while reading samples from '%s'.\n", filename);
goto error_cleanup;
}
<minor snip>
/* Fill in the sound data structure. */
sound->freq = file_info.samplerate;
sound->size = file_info.samples * file_info.channels * file_info.pcmbitwidth / 8;
/* Give our sound data to OpenAL. */
alGenBuffers(1, &sound->name);
if (alGetError() != AL_NO_ERROR) {
printf("Error creating an AL buffer name for %s.\n", filename);
goto error_cleanup;

goto error_cleanup;
}
/* Close the file and return success. */
sf_close(file);
free(buffer_short);
free(buffer_8);
return 0;
error_cleanup:
if (file != NULL) fclose(file);
free(buffer_short);
free(buffer_8);
return -1;
}
As you can see, the PCM material in the listing will not currently
compile and for the other sndfile material, it probably won't either.
Any help would be appreciated.

None of the changes above should have been very difficult to figure

new_file_type.HOWTO
===================
Original : Wed May 23 19:05:07 EST 2001
Update 1 : Fri Jul 11 22:12:38 EST 2003
This document will attempt to explain as fully as possible how to add code to
libsndfile to allow the reading and writing of new file types. By new file
type I particularly mean a new header type rather than a new encoding method
for an existing file type.
This HOWTO will take the form of a step by step guide. It will assume that you
have all required tools including :
- gcc
- make (should really be the GNU version)
- autoconf
- automake
- libtool
These should all be available on the GNU ftp site: ftp://ftp.gnu.org/pub/gnu/.
To help make these steps clearer let's suppose we are adding support for the
Whacky file format whose files contain 'W','A','C' and 'K' as the first four
bytes of the file format. Lets also assume that Whacky files contain PCM encoded
data.
Step 1
------
Create a new .c file in the src/ directory of the libsndfile source tree. The
file name should be reasonable descriptive so that is is obvious that files of
the new type are handled by this file. In this particular case the file might
be named 'whacky.c'.
Step 2
------
Add your new source code file to the build process.
Edit the file src/Makefile.am and add the name of your file handler to the
FILESPECIFIC list of handlers. This list looks something like this:
FILESPECIFIC = aiff.c au.c au_g72x.c nist.c paf.c raw.c samplitude.c \
svx.c wav.c wav_float.c wav_gsm610.c wav_ima_adpcm.c \
wav_ms_adpcm.c
Then, run the script named 'reconf' in the libsndfile top level directory,
which will run autoconf and other associated tools. Finally run "./configure"
in the top level directory. You may want to use the "--disable-gcc-opt" option
to disable gcc optimisations and make debugging with gdb/ddd easier.
Step 3
------
Add a unique identifier for the new file type.
Edit src/sndfile.h.in and find the enum containing the SF_FORMAT_XXX identifiers.
Since you will be adding a major file type you should add your identifier to the
top part of the list where the values are above 0x10000 in value. The easiest
way to do this is to find the largest value in the list, add 0x10000 to it and
make that your new identifier value. The identifier should be something like
SF_FORMAT_WACK.
Step 4
------
Add code to the file type recogniser function.
Edit src/sndfile.c and find the function guess_file_type (). This function
reads the first 3 ints of the file and from that makes a guess at the file
type. In our case we would add:
if (buffer [0] == MAKE_MARKER ('W','A','C','K'))
return SF_FORMAT_WACK ;
The use of the MAKE_MARKER macro should be pretty obvious and it is defined at the
top of file should you need to have a look at it.
Step 5
------
Add a call to your open function from psf_open_file ().
Edit src/sndfile.c and find the switch statement in psf_open_file (). It starts
like this:
switch (filetype)
{ case SF_FORMAT_WAV :
error = wav_open (psf) ;
break ;
case SF_FORMAT_AIFF :
error = aiff_open (psf) ;
break ;
Towards the bottom of this switch statement your should add one for the new file
type. Something like:
case SF_FORMAT_WACK :
sf_errno = whacky_open (psf) ;
break ;
Setp 6
------
Add prototypes for new open read and open write functions.
Edit src/common.h, go to the bottom of the file and add something like
int whacky_open (SF_PRIVATE *psf) ;
Step 7
------
Implement your open read function. The best way to do this is by coding
something much like one of the other file formats. The file src/au.c might be
a good place to start.
In src/whacky.c you should now implement the function whacky_open() which
was prototyped in src/common.h. This function should return 0 on success and
a non-zero number on error.
Error values are defined in src/common.h in a enum which starts at SFE_NO_ERROR.
When adding a new error value, you also need to add an error string to the
SndfileErrors array in src/sndfile.c.
To parse the header of your new file type you should avoid using standard read/
write/seek functions (and the fread/fwrite/fseek etc) and instead use
psf_binheader_readf () which is implemented and documented in src/common.h.
During the parsing process, you should also print logging information to
libsndfile's internal log buffer using the psf_log_printf() function.
At the end of the open read process, you should have set a number of fields in the
SF_PRIVATE structure pointed to by psf.

<H1><B>libsndfile and GNU Octave</B></H1>
<P>
<A HREF="http://www.octave.org/">GNU Octave</A> is a high-level interactive
language for numerical computations.
There are currently two development streams, a stable 2.0.X series and a
development 2.1.X series.
Octave reads and writes data in binary formats that were originally developed
for
<A HREF="http://www.mathworks.com/">MATLAB</A>.
Version 2.0.X of Octave uses binary data files compatible with MATLAB
version 4.2 while Octave 2.1.X uses binary data files compatible
with MATLAB version 5.0 as well as being able to read the older MATLAB 4.2
format.
</P>
<P>
From version 1.0.1 of libsndfile onwards, libsndfile has the ability of reading
and writing a small subset of the binary data files used by both versions
of GNU Octave.
This gives people using GNU Octave for audio based work an easy method of
moving audio data between GNU Octave and other programs which use libsndfile.
</P>
<P>
For instance it is now possible to do the following:
</P>
<UL>
<LI> Load a WAV file into a sound file editor such as
<A HREF="http://www.metadecks.org/software/sweep/">Sweep</A>.
<LI> Save it as a MAT4 file.
<LI> Load the data into Octave for manipulation.
<LI> Save the modified data.
<LI> Reload it in Sweep.
</UL>
<P>
Another example would be using the MAT4 or MAT5 file formats as a format which
can be easily loaded into Octave for viewing/analyzing as well as a format
which can be played with command line players such as the one included with
libsndfile.
</P>
<H2><B>Details</B></H2>
<P>
Octave, like most programming languages, uses variables to store data, and
Octave variables can contain both arrays and matrices.
It is also able to store one or more of these variables in a file.
When reading Octave files, libsndfile expects a file to contain two
variables and their associated data.
The first variable should contain a variable holding the file sample rate
while the second variable contains the audio data.
</P>
<P>
For example, to generate a sine wave and store it as a binary file which
is compatible with libsndfile, do the following:
</P>
<PRE>
octave:1 > samplerate = 44100 ;
octave:2 > wavedata = sin ((0:1023)*2*pi/1024) ;
octave:3 > save sine.mat samplerate wavedata
</PRE>
<P>
The process of reading and writing files compatible with libsndfile can be
made easier by use of two Octave script files :
</P>
<PRE>
octave:4 > [data fs] = sndfile_load ("sine.mat") ;
octave:5 > sndfile_save ("sine2.mat", data, fs) ;
</PRE>
<P>
In addition, libsndfile contains a command line program which which is able
to play the correct types of Octave files.
Using this command line player <B>sndfile-play</B> and a third Octave script
file allows Octave data to be played from within Octave on any of the platforms
which <B>sndfile-play</B> supports (at the moment: Linux, MacOS X, Solaris and
Win32).
</P>
<PRE>
octave:6 > sndfile_play (data, fs) ;
</PRE>
<P>
These three Octave scripts are installed automatically in Octave's site
script directory when libsndfile is installed (except on Win32) ie when
libsndfile is being installed into /usr/local, the Octave scripts will
be installed in /usr/local/share/octave/site/m/.
</P>
<P>
There are some other Octave scripts for audio to be found
<A HREF="http://octave.sourceforge.net/audio/index.html">here</A>.

<H1>libsndfile and pkg-config</H1>
<P>
From version 1.0.0 libsndfile has had the ability to read and write files of
greater than 2 Gig in size on most OSes even if sizeof (long) == 4.
OSes which support this feature include Linux (2.4 kernel, glibc6) on x86, PPC and
probably others, Win32, MacOS X, *BSD, Solaris and probably others.
OSes on 64 bit processors where the default compile environment is LP64 (longs and
pointers are 64 bit ie Linux on DEC/Compaq/HP Alpha processors) automatically
support large file access.
</P>
<P>
Other OSes including Linux on 32 bit processors, 32 bit Solaris and others require
special compiler flags to add large file support.
This applies to both the compilation of the library itself and the compilation of
programs which link to the library.
</P>
<P>
Note : People using Win32, MacOS (both OS X and pre-OS X) or *BSD can disregard the
rest of this document as it does not apply to either of these OSes.
</P>
<P>
The <B>pkg-config</B> program makes finding the correct compiler flag values and
library location far easier.
During the installation of libsndfile, a file named <B>sndfile.pc</B> is installed
in the directory <B>${libdir}/pkgconfig</B> (ie if libsndfile is installed in
<B>/usr/local/lib</B>, <B>sndfile.pc</B> will be installed in
<B>/usr/local/lib/pkgconfig/</B>).
</P>
<P>
In order for pkg-config to find sndfile.pc it may be necessary to point the
environment variable <B>PKG_CONFIG_PATH</B> in the right direction.
</P>
<PRE>
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
</PRE>
<P>
Then, to compile a C file into an object file, the command would be:
</P>
<PRE>
gcc `pkg-config --cflags sndfile` -c somefile.c
</PRE>
<P>
and to link a number of objects into an executable that links against libsndfile,
the command would be:
</P>
<PRE>
gcc `pkg-config --libs sndfile` obj1.o obj2.o -o program
</PRE>
<P>
Obviously all this can be rolled into a Makefile for easier maintenance.
</P>

<P><B>
Note : For pre-compiled binaries for windows, both for win32 and win64, see the
main web page.
</B></P>
<P>
There is currently only one way of building libsndfile for Win32 and Win64;
cross compiling from Linux using the MinGW cross compiler.
</P>
<P>
libsndfile is written to be compiled by a compiler which supports large
chunks of the 1999 ISO C Standard.
Unfortunately, the microsoft compiler supports close to nothing of this
standard and hence is not suitable for libsndfile.
</P>
<P>
It <b>may</b> be possible to compile libsndfile on windows using the
<a href="http://www.mingw.org/">MinGW</a>
compiler suite, but I haven't tested that and have no interest in supporting
that.

**
** How to use:

**
** - You must edit this file to point to the file you want to convert. Set

** to the name of a .WAV file that exists on your system.
** 186: string sfn = "input.wav";
**
** - From a command prompt type
** csc generate.cs
**
** - Run the resulting executable 'generate.exe'
**
**
** Note: You will obviously need the csc compiler and the .NET runtime. I think
** these are freely available for download from Microsoft's website
** (part of the .NET SDK?).
