idk how that usually works

@aeva saw wave through a formant filter: a two (or more) pole resonant low pass. https://en.wikipedia.org/wiki/Formant#Formant_plots

@epilanthanomai from reading the article it sounds like a saw wave + some noise, a feedback loop, and a lowpass filter might be able to produce something basic?

@aeva The traditional chorus effect is sound + sound * vibrato. I always thought it was a sine wave vibrato, but others in this thread seem to be suggesting saw wave.

If the vibrato is balanced and starts with taking the pitch lower you’ll never need samples from the future. Right when the vibrato cursor catches up to the present, it’s time to get behind again.

So overall the formula is out[x] = in[x] + in[x + offset] where offset is a sine wave that starts at 0 and goes to -1 and back to 0.

@epilanthanomai ok that was really easy :) ty :D

[epilanthanomai@signs.codes]

@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.

@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?
