Real-time RPG music
synced to every player.
Trigger a scene and the soundtrack starts in every player's browser at the same moment. Director hotkeys, cinematic crossfades, frame-level sync.
Frame-accurate playback
When you press play, every player's browser plays the same instant. Reconnects re-hydrate to the exact playhead position.
Director hotkeys
Press 1 for Tavern, 2 for Combat, 3 for Boss. Conduct the soundtrack like a film score without breaking eye contact with the table.
Cinematic scene transitions
Black-card intros, hand-tuned crossfades, and live pause/resume. Music, ambience and visuals fade as one.
Reconnect recovery
A player closes their laptop mid-session? When they come back, the music is exactly where it should be.
Works on every device
Browser-based, no installs. Phones, tablets, laptops — all stay in lockstep.
YouTube-powered
Drop a link, assign to a scene. Google's official iframe player handles the rest — no downloads, no licensing headaches.
FAQ
About RPG music sync
How does RPG music sync work?
RealmCaster runs a realtime channel for every room. When the DM triggers a scene, every connected player's browser receives the playback state — track, position, volume — and locks to it within milliseconds.
What if a player joins late?
Late joiners and reconnects hydrate to the current scene's exact playhead position automatically. No 'where are we?' moment.
Do I need to upload music files?
No. RealmCaster uses YouTube's official iframe API. Paste a link, assign it to a scene, and you're ready to play.
Is it really synchronized?
Yes — playback events broadcast in real time and we periodically reconcile against server state. Players who background their tab self-correct when they return.
