\section g726_tests_page_sec_1 What does it do?
|
||
Two sets of tests are performed:
|
||
- The tests defined in the G.726 specification, using the test data files supplied with
|
||
the specification.
|
||
- A generally audio quality test, consisting of compressing and decompressing a speeech
|
||
file for audible comparison.
|
||
|
||
The speech file should be recorded at 16 bits/sample, 8000 samples/second, and named
|
||
"pre_g726.wav".
|
||
|
||
\section g726_tests_page_sec_2 How is it used?
|
||
To perform the tests in the G.726 specification you need to obtain the test data files from the
|
||
specification. These are copyright material, and so cannot be distributed with this test software.
|
||
|
||
The files, containing test vectors, which are supplied with the G.726 specification, should be
|
||
copied to itutests/g726 so the files are arranged in the same directory heirarchy in which they
|
||
are supplied. That is, you should have file names like
|
||
|
||
- itutests/g726/DISK1/INPUT/NRM.M
|
||
- itutests/g726/DISK1/INPUT/OVR.M
|
||
- itutests/g726/DISK2/INPUT/NRM.A
|
||
- itutests/g726/DISK2/INPUT/OVR.A
|
||
|
||
in your source tree. The ITU tests can then be run by executing g726_tests without
|
||
any parameters.
|
||
|
||
To perform a general audio quality test, g726_tests should be run with a parameter specifying
|
||
the required bit rate for compression. The valid parameters are "-16", "-24", "-32", and "-40".
|
||
The test file ../test-data/local/short_nb_voice.wav will be compressed to the specified bit rate,
|
||
decompressed, and the resulting audio stored in post_g726.wav.
