Generated on the Apple TV, from the track that’s playing
Most TV music visualizers are pre-rendered clips on a timer. Theatrium's are generated on the Apple TV itself, in real time, driven by what's actually playing: the track's tempo (BPM), the colors in its album art, and its title. Scenes reshuffle their look each time a song plays, so the same track rarely looks the same way twice. This works with Apple Music on the Apple TV itself, or with Spotify, Last.fm and Plex mirrored from your phone or computer — and with any Home Assistant media_player source, including Music Assistant.
The visualizer responds only to track changes, tempo and album art. It does not listen to the room and does not use the microphone.
Every scene is below, grouped the way the app groups them on the TV. All of them are captured from Theatrium running on an Apple TV — nothing here is a mockup.
Album Art 4 scenes
Built from the cover art of whatever is playing. All four captures here use the same stand-in cover, so what changes between them is the scene, not the artwork.
Calm 5 scenes
Slow, low-contrast fields meant to be left running in a room someone is actually living in.
Kinetic 7 scenes
Faster and higher-contrast. These push hardest at the track’s tempo, and they are the ones that carry a party.
Fractal 5 scenes
Mathematical fields, deep-zoomed and recoloured from the album art, each descending in time with the track's tempo.
Retro 4 scenes
Physical objects rendered around whatever is playing, down to the track name on the cassette label.
Brand 4 scenes
Spectrum scenes tuned specifically for handing their colors to the room lights below.
