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
