Drop a track to get a beat-locked visual you can export for Reels, TikTok, and Spotify Canvas.

How to use the Music Visualizer

  1. Drop your audio file

    Choose an MP3, WAV, M4A, OGG, or FLAC file up to 50MB. It is decoded and analyzed in your browser, so nothing uploads.

  2. Watch it come alive

    The tool reads the tempo, beat grid, key, and energy of your track, then plays a visual that moves in time with the music.

  3. Export for your platform

    Pick a format for Spotify Canvas, Reels, TikTok, or a square post, then record the video and download it.

Frequently asked questions

Does my audio get uploaded anywhere?

No. Your file is decoded and analyzed entirely in your browser. The audio never leaves your device, so nothing is stored on a server.

What video formats can I export?

You can export a 9:16 Spotify Canvas loop, a full-length 9:16 Reel or TikTok clip, a 1:1 square, or a 16:9 wide video. The recording is a WebM file, which uploads to Instagram, TikTok, and YouTube. Once your clip is ready, the Caption & Hook Writer gives you a caption to post it with, and a Smart Music Link puts the track one tap away on every streaming platform.

Which browser works best for recording?

Recording works best in Chrome, Edge, or Firefox. In Safari, the visual exports as a zip of PNG frames you can assemble into a video instead.

Is the visual the same every time for the same song?

Yes. The visual is a function of the track analysis and your style settings, so the same song with the same settings always produces the same result. If you just want to read the tempo and key on their own, the BPM & Key Detector reports them in seconds.

Do I need an account or a subscription?

No. This tool is free, needs no sign-up, and adds no watermark to your export.
