[chuck-users] Convolution Reverb (Posed by: Julien Saint-Martin)

If the impulse response is short enough, or real-time isn’t important, then the FIR chugin can be used.

FFT-based convolution is possible using the FFT/iFFT UANAs, but latency and real-time are issues.  To deal with that, It would be possible to factor into a nice systolic topology using shorter FFTs and delay lines to line everything up.  

I don’t know of a specific chugin or example other than those.  

Someone should write one :-))
