Hi Kassen,
Thanks for the responses! Yeah, Eduard's code works perfectly, I just
altered the values enough to throw it off. I emailed him directly, and he
helped me sort it out. Here's the quoted text:
just to start with, the fftsize has to be a multiple of 2, so 2500 is not an
> optimal size. It should be 2048 (pow(2,11)) or 4096 (pow(2,12)) or 1024
> (pow(2,10))... although you can still use any size, it's better to use a
> power of two, which in chuck is Math.pow(2,n) where n is the number you are
> rising 2 to. A good size is 2048, so n=10. Otherwise the code does not make
> sense... for instance FFT_SIZE/8. That only makes sense if FFT_SIZE is a
> power of 8 which in turn is a power of 2 (2^3=8).

Any other vocoding wisdom or expertise anyone has to share, I'm all ears.
This stuff is really cool.
