|
|
* This group of IOCTLs deal with the record settings of the DSP
|
|
*
|
|
* The IXJCTL_REC_DEPTH command sets the internal buffer depth of the DSP.
|
|
* Setting a lower depth reduces latency, but increases the demand of the
|
|
* application to service the driver without frame loss. The DSP has 480
|
|
* bytes of physical buffer memory for the record channel so the true
|
|
* maximum limit is determined by how many frames will fit in the buffer.
|
|
*
|
|
* 1 uncompressed (480 byte) 16-bit linear frame.
|
|
* 2 uncompressed (240 byte) 8-bit A-law/mu-law frames.
|
|
* 15 TrueSpeech 8.5 frames.
|
|
* 20 TrueSpeech 6.3,5.3,4.8 or 4.1 frames.
|
|
*
|
|
* The default in the driver is currently set to 2 frames.
|
|
*
|
|
* The IXJCTL_REC_VOLUME and IXJCTL_PLAY_VOLUME commands both use a Q8
|
|
* number as a parameter, 0x100 scales the signal by 1.0, 0x200 scales the
|
|
* signal by 2.0, 0x80 scales the signal by 0.5. No protection is given
|
|
* against over-scaling, if the multiplication factor times the input
|
|
* signal exceeds 16 bits, overflow distortion will occur. The default
|
|
* setting is 0x100 (1.0).
|
|
*
|
|
* The IXJCTL_REC_LEVEL returns the average signal level (not r.m.s.) on
|
|
* the most recently recorded frame as a 16 bit value.

|
|
* The IXJCTL_TONE_CADENCE ioctl defines tone sequences used for various
|
|
* Call Progress Tones (CPT). This is accomplished by setting up an array of
|
|
* IXJ_CADENCE_ELEMENT structures that sequentially define the states of
|
|
* the tone sequence. The tone_on_time and tone_off time are in
|
|
* 250 microsecond intervals. A pointer to this array is passed to the
|
|
* driver as the ce element of an IXJ_CADENCE structure. The elements_used
|
|
* must be set to the number of IXJ_CADENCE_ELEMENTS in the array. The
|
|
* termination variable defines what to do at the end of a cadence, the
|
|
* options are to play the cadence once and stop, to repeat the last
|
|
* element of the cadence indefinatly, or to repeat the entire cadence
|
|
* indefinatly. The ce variable is a pointer to the array of IXJ_TONE
|
|
* structures. If the freq0 variable is non-zero, the tone table contents
|
|
* for the tone_index are updated to the frequencies and gains defined. It
|
|
* should be noted that DTMF tones cannot be reassigned, so if DTMF tone
|
|
* table indexs are used in a cadence the frequency and gain variables will
|
|
* be ignored.
|
|
*
|
|
* If the array elements contain frequency parameters the driver will
|
|
* initialize the needed tone table elements and begin playing the tone,
|
|
* there is no preset limit on the number of elements in the cadence. If
|
|
* there is more than one frequency used in the cadence, sequential elements
|
|
* of different frequencies MUST use different tone table indexes. Only one
|
|
* cadence can be played at a time. It is possible to build complex
|
|
* cadences with multiple frequencies using 2 tone table indexes by
|
|
* alternating between them.
