Adaptive distortion manager for use with an acoustic echo canceler and a method of operation thereof

摘要

A distortion manager and a method of managing distortion for use with an acoustic echo canceler. In one embodiment, the distortion manager includes a coherence ascertainer coupled to an adaptive distortion adder. The coherence ascertainer determines a coherency between audio streams and the adaptive distortion adder selectively adds non-linear distortion to at least one of the audio streams based on the coherency.
