So i did take a look :-), and i have found Speex preprocessor too, it seens
to have noise supression (even other features can be implemented using
speex, like VAD and AGC).

What about a plugin using speex to do general preprocessing? (AGC, Noise
suppression, residual echo suppression).

Im also studying the Gnome Wave Cleaner code.
