About this tool
Find BPM and musical key from any upload
The Unmix Key & BPM Finder estimates tempo and key from MP3 or WAV uploads — useful before mashups, DJ sets, cover practice, or lining up clips in the Music Editor. Results are approximate and work best on clear, full-mix recordings.
Use detected BPM to snap clips in the editor, match practice tracks to your vocal range with pitch tools, or plan transitions between songs. No install — analyze in the browser and move on to the next step in your workflow.

FAQ
How accurate is the BPM and key detection?
Estimates are best on modern, well-mixed songs with a steady beat. Live recordings, heavy swing, or dense polyrhythms may vary. Always trust your ears for final performance decisions.
Do I need to remove vocals first?
No. The analyzer works on full mixes. For mashups, knowing both tracks' BPM and key helps you decide whether to pitch-shift before blending.
Can I use BPM results in the Music Editor?
Yes. Note the detected tempo, then set project BPM in the editor so clips snap to the grid when arranging stems or loops.
