Systems and methods of monitoring performance of acoustic echo cancellation
View Patent ↗Methods and systems monitoring performance of acoustic echo cancellation are described. An audio output is generated by applying a first acoustic echo cancellation algorithm to an audio input. One or more performance metrics for the first acoustic echo cancellation algorithm based on the audio output are determined via a second acoustic echo cancellation algorithm. The first acoustic echo cancellation algorithm is different from the second acoustic echo cancellation algorithm. The one or more performance metrics are provided for storage in a memory.
