Wow, didn't know it was that simple.  I'll give it a shot later and report back.  Thanks!

Hi Kevin,
sorry for not anwering earlier - i'm abroad an not very netty at the moment.
VASP offers non-granular Fourier transformation, which enables non-windowed convolution.
Convolution translates to multiplication in the spectral domain, therefore just  fourier-transform your two buffers (zero-padded to the same size) into the spectral domain, multiply the results, transform back, there you go.

greetings,
Thomas

Hello all,

I would like to hear how some FFT-based convolution sounds with VASP, which claims to leave fewer artifacts than the hann-windowed realtime FFT, but the included example "convolution" does not produce results for me - I load the sound files and send them to the tables via wedit but the final table (I think it's called buf_res) does not receive anything - in other words, no results.

I'm looking to do something like the "timbre stamp" FFT example in Pd's documentation - I've gotten so many wild and beautiful sounds from running tabread4~ based samples against each other through this, but the quality is not always very crisp.  If anyone has any patches or info, let me know.

Thanks!
Kevin
