A visualiser over whatever is playing

Put a station on, then open this. The picture reacts to the sound, in your browser, and the settings are yours to keep.

Reacts to the radio

The visualiser reads the audio the player is already producing — the same stream, analysed in your tab. Nothing leaves your device and nothing is recorded.

Presets and knobs

Pick a style, turn the intensity, choose a palette, or jump into a preset. Signed in, the settings follow you to another device.

Make a video of it

The same visual engine renders music videos at reactive-music.leumas.tech. There is one visualiser and two doors into it, rather than two copies to keep in step.
