By specifying the define WEBRTC_DUMMY_FILE_DEVICES (which is similar to WEBRTC_DUMMY_AUDIO_BUILD) an application will be able to tell WebRTC to play out audio to a file and feed audio in from a file. We want to do so we can better test WebRTC-using applications by recording what the audio stack outputs and feeding known audio in for quality tests.
