hi robert, feedback suppression should be quite easy to achive w/ the vasp external. fft the incoming signal. check if there are 1 or 2 bands which are much louder than their neighbours. if so multiply that bands which an adjustable value <1 and than take the ifft. feedback noise is a pure sine (until it's getting so loud that it' distorts) so they don't have overtones and cause a significant peak in at most 2 neighbouring bands.
