fmvoice — FM Singing Voice Synthesis

## Description

FM Singing Voice Synthesis

## Syntax

    ares fmvoice kamp, kfreq, kvowel, ktilt, kvibamt, kvibrate, ifn1, \
          ifn2, ifn3, ifn4, ivibfn

## Initialization

ifn1, ifn2, ifn3,ifn3 -- Tables, usually of sinewaves.

## Performance

kamp -- Amplitude of note.

kfreq -- Frequency of note played.

kvowel -- the vowel being sung, in the range 0-64

ktilt -- the spectral tilt of the sound in the range 0 to 99

kvibamt -- Depth of vibrato

kvibrate -- Rate of vibrato

## Examples

Here is an example of the fmvoice opcode. It uses the file fmvoice.csd.

Example 175. Example of the fmvoice opcode.
