    Teensy4 600MHz 1.48 , IDE 1.8.10, compile mode is debug.

    How do I tell if the version I have has the debug information issue? I assume the version that fixed this was pushed to GitHub?

    Found the origin of the artefacts- I was feeding FreeverbStereo two channels instead of one- that overwrote one of the internal comb filter buffers silently and introduced a periodic noise. However,...
  8. AudioEffectFreeverbStereo - self-resonates with (internal) noise impulse?

    With damping set to 0, I've had some very odd periodic noise impulse artefacts turning up in the output of FreeVerbStereo, even with the input at 0 volume over sustained periods.
