- * 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

- * 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

- * The IXJCTL_TONE_CADENCE ioctl defines tone sequences used for various

- * 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.
