BPM Detector Tool

Try it now! ↗️
The BPM Detector analyzes an audio file and tells you its tempo — useful for matching beats, planning remixes, or syncing layers in the Studio. Detection runs entirely in your browser, so the audio never leaves your device.

​
How to use it

Drop in an audio file (MP3, WAV, FLAC, OGG, M4A, AAC) or pick one from your library. The tool decodes the track locally with web-audio-beat-detector and returns a BPM value between 20 and 300. You can also override the detected value manually if you already know the tempo.

You can override the BPM with any value between 20 and 300 — useful for half-time / double-time songs where the algorithm picks the wrong multiple.
Tracks with a clear, consistent beat. Free-tempo or rubato performances may not return a meaningful BPM.
