I don't know what CAPS is using, and ATM I can't really blame the biquads - I just have a feeling the problem could be hiding there. But using biquads in audio has some drawbacks: - in particular for filters operating at LF, you can have problems with numerical precision, - they can get unstable when parameters values are modified. This sort of thing happens often with the 'textbook' form of a DSP algo, which is almost never the right one to use. -- FA Follie! Follie!
