What audio formats does MusicMind support?

MP3, WAV, FLAC, OGG, and AAC. The engine uses the Web Audio API to decode audio, so anything your browser can play, MusicMind can analyze.

Does MusicMind upload my audio files?

No. Your audio never leaves the browser. All audio analysis runs in your browser using the Web Audio API.

How is MusicMind different from other visualizers?

Most visualizers react to volume. MusicMind's 13-layer engine detects musical key, estimates bass, drum and vocal energy bands, classifies beat types, and maps emotional arcs. Your visuals change when the key shifts, explode on the kick drum, and transition when the song structure changes.

Can I make a Spotify Canvas with MusicMind?

Yes. Export a vertical 9:16 video (3–8 seconds, looping) and upload it directly as a Spotify Canvas. MusicMind times the loop to the beat grid.

Music intelligence, measured.

Your audio never leaves your browser.

Every analysis runs client-side on the Web Audio API and WebGL. The audio file is never uploaded. If you sign in and share a report, the report's numbers are saved so the page can be served; the audio is not.
