What it does

Everything you need to make sound visible

🎚️

Audio-reactive engine

A live analysis core reads bass, mids, highs, brightness, attack, and pitch — and drives the artwork from them, frame by frame.

🔊

Captures your system audio

Point it at whatever's playing on your Mac — DJ software, music apps, a browser — with no loopback driver or virtual cable. Or stream in any audio input — a mic, a USB interface, your DJ mixer — for live rooms and gigs.

🌀

2D & 3D fractals

27 types — flowing spirals, phyllotaxis, and Julia sets, plus ray-marched Mandelbulbs, Mandelboxes, Menger sponges, and gyroid surfaces. See them all →

🖥️

Built for the stage

Send the canvas fullscreen to a projector or LED wall. The audio-to-visual path is tuned for live use, so it stays tight to the beat.

🎬

Export anywhere

Record MP4, MOV, or WebM up to 4K, grab high-DPI PNG stills, and export 2D pieces as scalable SVG for print and merch.

🔒

Private by design

No sign-in, no analytics, no phone-home. Your audio is analyzed live and never recorded or transmitted. Nothing leaves your Mac.
