    Echo cancellation must now be controlled throgh IVSStageAudioManager.

    Indicates whether echo cancellation is enabled on the microphone device. By default this is NO. The value reported will be the instantaneous value on the input node, because the audio is managed on a background queue, the value may be changing in the background while this is queried.

    Changing this property while the microphone is in use may result in momentary audio loss. Setting this property to a value of YES may require microphone permissions.

    @property (nonatomic, assign, unsafe_unretained, readwrite,
          getter=isEchoCancellationEnabled) BOOL echoCancellationEnabled;

    Swift
