Hi everyone - Has anyone out there done much real-time convolution in PD? I found a thread from a while back where partconv~ and FIR~ are suggested, but not much else out there.. After trying them, I'm having different troubles with both.. partconv~ seems to load my system to the point where the audio is breaking up and the mouse moves really slow. (running Ubuntu linux, Alsa + Jack on a mini-itx 1Ghz motherboard, 512MB ram) FIR~ seems to work all right with smaller block sizes, but I can't figure out how to send a 44.1Khz signal through it as the "kernel" rather than initializing it with a static array. I want to convolve one moving signal with another one, and any ideas would be appreciated. cheers, -David Merrill
hi,

Hi, a very "musical" convolution effect is in the help patches: 4.fft.examples/08.convobros.pd marius.
