* 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.

* This IOCTL allows you to reassign values in the tone index table.  The

* 13 - 27 to be modified, entry 0 is reserved for silence and 1 - 12 are

* the standard DTMF digits and 28 - 31 are the DTMF tones for A, B, C & D.

* The positions used internally for Call Progress Tones are as follows:

*    Dial Tone   - 25

*    Ring Back   - 26

*    Busy Signal - 27

*

* The freq values are calculated as:

* freq = cos(2 * PI * frequency / 8000)

*

* The most commonly needed values are already calculated and listed in the

* enum IXJ_TONE_FREQ.  Each tone index can have two frequencies with

* different gains, if you are only using a single frequency set the unused

* one to 0.

*

* The gain values range from 0 to 15 indicating +6dB to -24dB in 2dB

* increments.

*

* The IXJCTL_TONE_CADENCE ioctl defines tone sequences used for various

* 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 indefinitely, or to repeat the entire cadence

* indefinitely.  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.
