Hello,

Is there SigmaDSP AFC(acoustic feedback cancell)Algorithm？ Or how to build a system to howling suppression?

1.I have given up ADI's pitch transposer，it works not very well(Frequency shifting).

2.Adaptive filter just like AEC Algorithm in the same way that an echo canceller removes echoes?

3.Automatic notch filter? And how to build it? It contains detection and notch filter，how auto to detect?

Has anyone implemented a similar function before?
