Abstract
A system and method for processing multi-channel audio signals is described herein. In one embodiment, the system includes a phase detector to determine, for a frequency band, a phase difference between first and second channel signals of the multi-channel digital audio signal. In one embodiment, the system also includes an attenuator to attenuate an amplitude of the frequency band if the phase difference exceeds a first predetermined threshold.
