Mar 3, 2014. #3. If the microphone location is fixed with respect to the speaker, and the offending oscillation frequency is fairly repeatable, then a Twin-T notch filter should pick off the offending freq with minimal impact. Two flavors, a passive network in series with the audio, and an active circuit where the twin-T network is in an opamp ...
