Patent ID: 7227959

Claim:
A multi-channel acoustic system comprising: a first channel element that detects a first acoustic feedback component of a first acoustic signal and that processes the first acoustic signal from a first performance microphone to ameliorate the first acoustic feedback component, the first acoustic feedback component corresponding to a first feedback path from at least one speaker to the first performance microphone, the first performance microphone and an associated acoustic source of the first performance microphone being located on a same performance stage; a second channel element that detects a second acoustic feedback component of a second acoustic signal from a second performance microphone and that processes the second acoustic signal to ameliorate the second acoustic feedback component, the second acoustic feedback component corresponding to a second feedback path from the at least one speaker to the second performance microphone, the second performance microphone and a corresponding acoustic source of the second performance microphone being located on the same performance stage; and a communications pathway between the first channel element and the second channel element, wherein one of the channel elements informs another channel element about detecting acoustic feedback by providing determined filter parameters, wherein the determined filter parameters characterize the acoustic feedback, and wherein the other channel element may continue searching for an associated acoustic feedback component while said one of the channel elements configures in accordance with the determined filter parameters.
