Hello there,I think I found something - when you open a track page (like this one: https://www.dsponlineconference.com/session/Frequency_Domain_Signal_Processing)...
Hmmm, no idea, but then why would you want to convolve the output of the reverb by itself? As far as I have experimented with audio, that won't bring any pleasant...
Maybe it has something to do with the way you have written you code. Can you post it?

Some ideas I had
