78 * This group of IOCTLs deal with the record settings of the DSP
80 * The IXJCTL_REC_DEPTH command sets the internal buffer depth of the DSP.
81 * Setting a lower depth reduces latency, but increases the demand of the
82 * application to service the driver without frame loss. The DSP has 480
83 * bytes of physical buffer memory for the record channel so the true
84 * maximum limit is determined by how many frames will fit in the buffer.
86 * 1 uncompressed (480 byte) 16-bit linear frame.

88 * 15 TrueSpeech 8.5 frames.
89 * 20 TrueSpeech 6.3,5.3,4.8 or 4.1 frames.
91 * The default in the driver is currently set to 2 frames.
93 * The IXJCTL_REC_VOLUME and IXJCTL_PLAY_VOLUME commands both use a Q8
94 * number as a parameter, 0x100 scales the signal by 1.0, 0x200 scales the
95 * signal by 2.0, 0x80 scales the signal by 0.5. No protection is given
96 * against over-scaling, if the multiplication factor times the input
97 * signal exceeds 16 bits, overflow distortion will occur. The default
98 * setting is 0x100 (1.0).

306 * The IXJCTL_TONE_CADENCE ioctl defines tone sequences used for various

308 * IXJ_CADENCE_ELEMENT structures that sequentially define the states of
309 * the tone sequence. The tone_on_time and tone_off time are in
310 * 250 microsecond intervals. A pointer to this array is passed to the
311 * driver as the ce element of an IXJ_CADENCE structure. The elements_used
312 * must be set to the number of IXJ_CADENCE_ELEMENTS in the array. The
313 * termination variable defines what to do at the end of a cadence, the
314 * options are to play the cadence once and stop, to repeat the last
315 * element of the cadence indefinitely, or to repeat the entire cadence
316 * indefinitely. The ce variable is a pointer to the array of IXJ_TONE
317 * structures. If the freq0 variable is non-zero, the tone table contents
318 * for the tone_index are updated to the frequencies and gains defined. It
319 * should be noted that DTMF tones cannot be reassigned, so if DTMF tone
