i did not find in any of them a low pass resonant filter but i'll have to investigate.
I made a (non-scientific, but sounds ok to my (bad) ears...) resonant low-pass filter, see attached. two zeros at 1/2 sampling rate, plus two poles (conjugate pair) that can be moved about controlled by audio input. The gain formula comes from Miller's book, iirc, and I probably misused it, but it seems to work ok.
thanks, cyrille
Thanks,
