About AudioVisualize

AudioVisualize is a free audio visualizer that turns any song, podcast clip or live microphone input into moving graphics — and lets you export the result as a video. The visualizing and the exporting run in your browser.

Why it exists

Most online visualizers ask you to upload your audio, create an account, or wait in a render queue. We think a visualizer should feel like an instrument: open it, play something, see it immediately.

So everything here happens on your own device. Audio is decoded with the Web Audio API, analysed frame by frame, and drawn on your graphics card with WebGPU (or WebGL 2 where WebGPU isn't available yet). Exports are recorded locally with the browser's built-in MediaRecorder. Nothing you load is sent to us, with one exception you start yourself: Analyze song, an optional paid step that times your lyrics to a song and sends a lower-quality copy, deleted when the job ends. The privacy policy has the details.

What you can do with it

• Visualize an audio file, your microphone, or the audio from another browser tab.
• Choose from 9 core styles (Music Spaces, Waveform, Bars, Particles, Radial, 3D Mesh, Spectrogram, Circular and Mirror) + 23 premium styles, and 26 color palettes or your own custom one.
• Render on a dark, gradient, image, transparent or green-screen background.
• Export WebM or MP4 video at 720p, 1080p, 9:16 vertical or 1:1 square, or save a single frame as a PNG.

Built-in demo tracks

The demo presets (EDM Drop, Lo-Fi Beat, Podcast Intro and the rest) are synthesised in your browser when the page loads — there's no audio file to download, and they're free to use in anything you make with the tool.

What's paid

The 9 core styles up to 1080p stay free, with no account. Free videos carry a small watermark. Removing it, the 23 premium styles and 4K export use credits or a Pro plan; premium styles preview free. See pricing.
