Our music visualizer
Sonoluma
SonolumaWatch your music dance.
Sonoluma listens to whatever is playing on your computer and turns it into moving light — a modern take on Cthugha, the visualizer that set 1990s screens on fire.

Audio is processed on your computer.
The screen becomes part of the music
Choose all system audio or a single app such as Spotify, Apple Music or a browser. Sonoluma follows the sound in real time without recording a track or sending it away.
Change the palette, motion and intensity while it runs. Keep the visualizer beside your music player, or switch to full screen and leave the controls out of sight.
A visualizer that behaves like a native app
The controls are quick, local and available from the keyboard or menu bar.
Change the atmosphere
The space bar steps through flame, swirl, ripple and tunnel motion, P and the arrow keys cycle fire, ice and other palettes, V changes the drawing style.
Window or full screen
A normal window while you work; F or a double-click fills the display, Esc brings the window back.
See what is playing
An optional overlay shows the current Spotify or Apple Music track without launching either app.
No account or analytics
Nothing to sign in to, no advertising, no tracking code. H shows every keyboard shortcut.
Where it came from
The glow returns
“An oscilloscope on acid”
That is how Cthugha described itself in the 1990s, when it made a generation of computers pulse with music. Its feedback buffer smeared an oscilloscope trace into colour and flame.
Sonoluma keeps that restless character, rebuilt as a native app for modern audio sources and graphics hardware.

Your audio stays on your computer
Sonoluma processes audio in memory to draw the visual and does not record or upload it. macOS asks for Screen & System Audio Recording permission; microphone access is used only when you choose a microphone or line-in.
