I'd call it audio_capture_thread_ until we do something else with it.

   if (fake_audio_capture_module_ == NULL) {
     return false;
   }
 
   peer_connection_factory_ = webrtc::CreatePeerConnectionFactory(
       rtc::Thread::Current(), rtc::Thread::Current(),
       fake_audio_capture_module_, NULL, NULL);
   if (!peer_connection_factory_) {
     return false;
