/* 4 Formant Synthesis Instrument */
|
|
/* by Perry R. Cook, 1995-96 */
|
|
/* This instrument contains an excitation */
|
|
/* singing wavetable (looping wave with */
|
|
/* random and periodic vibrato, smoothing */
|
|
/* on frequency, etc.), excitation noise, */
|
|
/* and four sweepable complex resonances. */
|
|
/* */
|
|
/* Measured Formant data (from me) is */
|
|
/* included, and enough data is there to */
|
|
/* support either parallel or cascade */
|
|
/* synthesis. In the floating point case */
|
|
/* cascade synthesis is the most natural */
|
|
/* so that's what you'll find here. */
|
|
/* */
|
|
/* For right now, there's a simple command*/
|
|
/* line score interface consisting of 3 */
|
|
/* letter symbols for the phonemes, =xx */
|
|
/* sets the pitch to x, + and - add and */
|
|
/* subtract a half step, and ... makes it */
|
|
/* keep doing what it's doing for longer. */
