Uhm. I'm not going into details ;). It was just a very naive approach
(without even the slightest DSP knowlegde) and it seemed to work. Well I
guess not. Go ahead and make it work better :)

It's not my filter by the way (it's based on some demo-code by Paul
Kellett - see AUTHORS for eMail) and I guess it's optimized for speed.
But with the CVS stuff (unlike V3.2) you can adjust it's input gain and
make it stop crackling - although it would be nice if you wouldn't have
to adjust this....
