An online music visualizer that turns a song into a video
Load a track, choose a style, and record a finished video. WaveForge is a music visualizer that runs entirely inside your browser — there is no software to install and no file to upload.
Free account: 3 thirty-second recordings a day at 1080p. No card needed.
What a music visualizer actually does
A music visualizer reads the frequency content of a track — the low end from the kick and bass, the midrange where vocals and melody sit, the high end carrying hats and air — and drives a moving image from those numbers. When the bass hits, something moves. When the hats come in, the edges light up.
The difference between a good visualizer and a bad one is whether the motion follows the music or just wobbles near it. WaveForge analyses the whole file before it draws a single frame, so the response is locked to the audio rather than chasing it.
Thirty-one styles, and you can stack them
The library spans six families: spectrum bars, radial and mirrored forms, waveform traces, 3D scenes like warp starfields and audio terrain, particle systems, and generative art that redraws itself as the track moves.
They are not mutually exclusive. The layer stack composites as many as you want — a particle field behind the spectrum, sparks in front of it, lyrics and a logo over the top — each with its own blend mode, opacity, colour offset and transform. Rotation, scale and mirroring apply to every style, so each one is a family of shapes rather than a fixed picture.
Every style takes your own colours, and the palette can react to loudness so the ramp shifts on the hits. There are preset palettes if you want to move fast, full manual control if you are matching cover art, and any finished combination can be saved as a Look and reloaded on the next track.
It runs on your machine, not a server
Decoding, analysis and rendering all happen in your browser. Your audio never leaves your computer, which means there is no upload wait, no queue behind other people, and no copy of your unreleased track sitting on someone else’s server.
Recording runs in real time while the track plays. Your device handles the visuals, so choose resolution and effects that it can record smoothly.

Questions
Is there a free music visualizer I can try first?
Yes. Create a free account for three thirty-second recordings each day at up to 1080p, resetting at midnight UTC. Every style and colour control is included, with no watermark and no card needed.
Do I need to install anything?
No. WaveForge runs in your browser. Recording requires browser audio and video capture support. Sign-in and the daily demo allowance need an internet connection.
How long does rendering take?
Allow the length of the passage you record, plus time to prepare and save the file. Recording captures the visuals and audio in real time while your track plays. Keep the tab visible until it finishes.
Try it on your own track
Every style renders live in your browser. Load a file and see what it looks like before deciding anything.
