About BPM Finder
BPMfinders started as a fix for something every DJ and bedroom producer runs into: you've got a track, and you need its tempo and key before you can mix it, remix it, or figure out why it works. Most tools out there are either paywalled, slow, or just wrong half the time.
This one analyzes the audio right in your browser. No uploads, no account, no ads slowing things down — drop a file in, get a tempo and key reading in a few seconds, and get back to the music.
Features
- Instant tempo detectionGet the BPM of a track in a few seconds by analyzing the beat directly in your browser — no waiting on a server.
- Real key detectionWorks out the musical key, major or minor, using the actual pitch content of the track, not a guess.
- Camelot wheel codesEvery key comes with its Camelot number, so you can tell at a glance which tracks mix well together.
- Vibe metricsEnergy, danceability, and happiness scores give you a fast read on a song's mood before you decide if it fits.
- Nothing leaves your deviceYour audio file is analyzed locally. It's never uploaded anywhere, so there's nothing to wait on and nothing to worry about.
- Built for every screenPhone, tablet, or desktop — the whole thing is responsive, with dark mode and 10 languages built in.
