  77 * This group of IOCTLs deal with the record settings of the DSP
  78 *
  79 * The IXJCTL_REC_DEPTH command sets the internal buffer depth of the DSP.
  80 * Setting a lower depth reduces latency, but increases the demand of the
  81 * application to service the driver without frame loss.  The DSP has 480
  82 * bytes of physical buffer memory for the record channel so the true
  83 * maximum limit is determined by how many frames will fit in the buffer.
  84 *
  85 * 1 uncompressed (480 byte) 16-bit linear frame.
  86 * 2 uncompressed (240 byte) 8-bit A-law/mu-law frames.
  87 * 15 TrueSpeech 8.5 frames.
  88 * 20 TrueSpeech 6.3,5.3,4.8 or 4.1 frames.

  90 * The default in the driver is currently set to 2 frames.
  91 *
  92 * The IXJCTL_REC_VOLUME and IXJCTL_PLAY_VOLUME commands both use a Q8

  94 * signal by 2.0, 0x80 scales the signal by 0.5.  No protection is given
  95 * against over-scaling, if the multiplication factor times the input
  96 * signal exceeds 16 bits, overflow distortion will occur.  The default
  97 * setting is 0x100 (1.0).
  98 *

 305 * The IXJCTL_TONE_CADENCE ioctl defines tone sequences used for various
 306 * Call Progress Tones (CPT).  This is accomplished by setting up an array of
 307 * IXJ_CADENCE_ELEMENT structures that sequentially define the states of
 308 * the tone sequence.  The tone_on_time and tone_off time are in
 309 * 250 microsecond intervals.  A pointer to this array is passed to the
 310 * driver as the ce element of an IXJ_CADENCE structure.  The elements_used
 311 * must be set to the number of IXJ_CADENCE_ELEMENTS in the array.  The
 312 * termination variable defines what to do at the end of a cadence, the
 313 * options are to play the cadence once and stop, to repeat the last
 314 * element of the cadence indefinitely, or to repeat the entire cadence
 315 * indefinitely.  The ce variable is a pointer to the array of IXJ_TONE
 316 * structures.  If the freq0 variable is non-zero, the tone table contents
 317 * for the tone_index are updated to the frequencies and gains defined.  It
 318 * should be noted that DTMF tones cannot be reassigned, so if DTMF tone
 319 * table indexes are used in a cadence the frequency and gain variables will
 320 * be ignored.
 321 *
 322 * If the array elements contain frequency parameters the driver will
 323 * initialize the needed tone table elements and begin playing the tone,
 324 * there is no preset limit on the number of elements in the cadence.  If
 325 * there is more than one frequency used in the cadence, sequential elements
 326 * of different frequencies MUST use different tone table indexes.  Only one
 327 * cadence can be played at a time.  It is possible to build complex
 328 * cadences with multiple frequencies using 2 tone table indexes by
 329 * alternating between them.
