// AudioCapturerSource is an interface representing the source for
// captured audio. An implementation will periodically call
// `CaptureCallback::Capture()` to pass the audio samples. All methods must be
// called on the same thread. The supplied `CaptureCallback` will be called on
// the same thread, except `Capture()`. Implementations should use a dedicated
// thread to receive the stream and call `CaptureCallback::Capture()` in order
// to ensure that the client receives the stream without delays.
