摘要:
An apparatus for selective AEC filter bypass is disclosed. A method and computer program product also perform the functions of the apparatus. An apparatus for selective AEC filter bypass is disclosed that includes a filter for an audio handling device that performs acoustic echo cancellation (AEC) on a microphone signal to produce an AEC-filtered microphone signal, a bypass controller that determines whether an AEC bypass parameter corresponding to an audio stream is enabled and a mixer that combines the audio stream with the AEC-filtered microphone signal to produce an AEC-filtered selectively combined signal in response to determining that the AEC bypass parameter corresponding to the audio stream is enabled.
