Free Online BPM Detector — Find the Tempo of Any Song

Need to know the BPM (beats per minute) of a track? Drop any MP3, WAV, FLAC, M4A or OGG file onto the tool above and our analyser will measure its tempo in seconds — right inside your browser. Your music is never uploaded: all of the audio analysis runs locally on your device, so it's fast, private and works with files of any size.

BPM is the heartbeat of a song. DJs use it to beatmatch and build smooth transitions, producers use it to set project tempo and sync samples, and runners and cyclists use it to match music to their pace. Whatever you need it for, this free tempo finder gives you an accurate reading with a single click.

Frequently asked questions

Is the BPM detector free?▾
Yes — it's 100% free, with no signup and no limits. Analyse as many songs as you like.
Is my music uploaded anywhere?▾
No. The audio is decoded and analysed entirely in your browser, so your files never leave your device.
How accurate is the detected BPM?▾
It's highly accurate for music with a steady beat. For tracks with tempo changes or a weak pulse, the detector may report a half-time or double-time value — both are shown so you can pick the right one.
What are typical BPM ranges by genre?▾
As a rough guide: hip-hop/rap 85–115, pop 100–130, house 120–130, techno 120–150, dubstep 138–142, and drum & bass 160–180 BPM.
Which audio formats are supported?▾
Anything your browser can decode — typically MP3, WAV, FLAC, M4A/AAC and OGG.
