TrackTune

TrackTune live streams race announcer audio to fans' mobile devices with sub-second latency using the Dolby Millicast Flutter SDK for WebRTC. Low latency enables fans on-site to hear the announcer in real-time, even through the roar of the engines. To deliver an extended announcer stream, the app must be capable of playing audio while backgrounded. Streams are available for listening when our participating tracks are broadcasting. We do not support on-demand streaming at present, so it's not possible to stream audio with our app when no tracks are broadcasting. Tracks using TrackTune have the option to geofence their events to a specified radius, encouraging fan attendance. TrackTune uses location services to enforce geofencing when a user attempts to subscribe to a stream.
