@epilanthanomai interesting. i realized after i said i got it working i had inadvertently disabled the feedback to make it sound better. what sort of distance should f1 and f2 have?
@aeva Likely so. I have more experience reading spectrograms and theory, and less implementing it from scratch. The starting points I've read often skip the feedback system entirely and focus straight in on the two-pole resonant filter. A lot of the magic is in the psychoacoustics of the F1 and F2 resonant frequencies. You can make a lot of different waveforms sound like vowels with those.
