Vowel class transition steepness

[dietcv]

is there any particular reason to use the vowel class vs. mod FM or single sideband PM to create formants?

GlitchFree Vowel synthesis - with Soprano/tenor etc Formant tables

to demistify the two approaches: The two windows i have been using for either of the approaches are nearly identical in behaviour and have one common feature, they collapse to 1 if the index is 0. ( var raisedCos = { |phase, index| var cosine = cos(phase * 2pi); exp(index.abs * (cosine - 1)); }; var gaussianWindow = { |phase, index| var halfCosCycle = sin(phase * pi) * index; exp(halfCosCycle.neg * halfCosCycle); }; { var index = 2; var rate = 100; var phase = Phasor.ar(DC.ar(0), rate…
