Abstract:
Detection of an uncorrelated component in a multi-channel acoustic signal is disclosed. In one example, the detection is based on a relation between (A) a difference in energy between two channels of the signal and (B) a threshold value that is based on an estimate of background energy of the acoustic signal.
