There are a couple very old forums about this, but nothing in a while, and I'm at a loss:
I'm using a high-feedback [comb~] pull pitches out of noisy sounds (like a resonator or string modeling), and then reining the FB back in with some soft clipping (just using [tanh~] for now, but there are more interesting options).
The problem I keep running into is that certain sounds result in something that looks like DC offset when it comes out of the filter; the resulting signal is fully outside of the -1/1 range and then centers back around 0 (using [capture~] confirms this). I'm not sure if this is truly DC offset, but it looks like it. Obviously, this results in the audio dropping out and bizarre things with the [tanh~], etc.
I have tried using a tapin~/tapout~ pair for this project as well, and run into similar problems. I wish I could give a better idea of the sort of input sounds that result in this DC offset, but I'm at a loss as to what causes it -- noises and pitches, sometimes loud, sometimes soft.
There's probably a really simple solution or obvious alternative to [comb~] or taps here...
Thanks in advance for your help.
