Replicate the iconic radio replay system used in Formula 1 — live in your sim racing broadcast. Built natively for OBS, real-time across all drivers, zero latency.
Racing Sim Radio is a live broadcast tool designed to bring the iconic F1 team radio replay experience to sim racing streams. When a driver says something worth airing, your broadcast operator captures the moment, trims it, and fires it to your OBS stream — complete with the F1-style animated overlay and radio chirp.
Drivers connect from any device using their microphone. The controller monitors all feeds in real time, freezes the waveform when a clip is worth using, trims to the exact moment, previews it privately, then fires it to the stream. The overlay animates in with the driver's name, the audio plays, and it disappears cleanly once finished.
Built on WebRTC — no servers, no installs, no accounts. Works in any modern browser. Designed to run alongside OBS with a transparent browser source overlay at 1280×720.
