AudioVisualize is a free audio visualizer that runs entirely in your browser. Drop in a track or speak into your microphone, pick one of 32 visualizer styles, and export the animation as a WebM or MP4 video in a couple of clicks. Free exports need no account and no upload — the audio is analyzed locally with the Web Audio API, so nothing ever leaves your device.
We built this because a fifteen-second visualizer clip for a social post should not require installing a multi-gigabyte desktop editor. Everything renders on canvas in real time, so the preview you see is exactly what gets exported. Nine styles are free forever, including the classic spectrum and waveform looks; the full set of 32 covers bars, particles, radial, and abstract motion themes.
Optional AI backgrounds generate artwork behind the visuals when you want a quick, cohesive look — that is the only place AI is involved; the audio analysis and rendering are plain math on your machine. Ready-made profiles tune the experience for DJs, podcasters, musicians, and streamers, and our guides cover OBS overlays and export settings.
If you make music, host a podcast, or stream regularly, try loading your latest track and exporting a clip — the whole flow takes under a minute, and the result is ready for Reels, Shorts, or TikTok without any watermark games.
