The features have two safety fallbacks: - multichannel config has a killswitch WebRTC-Aec3SetupSpecificDefaultConfigDefaultsKillSwitch - stereo detection has a killswitch WebRTC-Aec3StereoContentDetectionKillSwitch Both features are enabled by default in the AEC3 config. Tested: Bitexact on a large number of aecdumps.
