@amir @nick yes, I got that. That's why I didn't release it. And you mean every s sound? I'll stick to v21.2 for now, as I don't have an idea how to improve it. I checked it multiple times against a recording of the external 22 kHZ output, and the differences seem to be very marginal now, if at all there. I will improve it further when I have an idea, but for now, I've run out of ideas.
