-// This class implements an AudioCaptureModule that can be used to detect if
-// audio is being received properly if it is fed by another AudioCaptureModule
-// in some arbitrary audio pipeline where they are connected. It does not play
-// out or record any audio so it does not need access to any hardware and can
-// therefore be used in the gtest testing framework.
-
-// Note P postfix of a function indicates that it should only be called by the
-// processing thread.
