Abstract
A system and method for removing feedback noise in an audio system includes an analyzing unit, which may utilize FFT processing and Feedback signal detection, and an adaptive feedback cancellation unit for removing the feedback noise, which may include, for example, 36 MR notch filters for one channel. A method to detect feedback noise in a substantially short amount of time combines increasing signal characteristics with full scale characteristics to find the feedback signal in a limited amount of time.
