fmvoice

FM Singing Voice Synthesis.

Syntax

ModernClassic

ares = fmvoice(kamp, kfreq, kvowel, ktilt, kvibamt, kvibrate[, ifn1, \
               ifn2, ifn3, ifn4, ivibfn])

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

Initialization

ifn1, ifn2, ifn3,ifn3, ivibfn -- Tables, usually of sinewaves. The last is for vibrato

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.
