About

Free real-time audio visualiser in the browser that reacts to microphone, files or shared system audio.

vizz.fm is a browser visualiser that needs no installation or account. It can listen to a microphone, a local audio file, a stream URL or, in Chromium-based browsers, system audio captured through screen sharing, which lets it react to Spotify or YouTube.

It offers dozens of visualisers with names such as Mesh Grid, Particle Dance and Frequency Hallway, with adjustable colour, speed, intensity and sensitivity, plus post-processing effects like kaleidoscope, bloom and CRT. Presets can be shared as links, and full-screen mode is suited to capture in OBS for streams. Video export was listed as in development at the time of checking.
