BPM Finder
Tap along to the beat, or drop a track and detect its tempo automatically. Confidence score plus half/double-time alternates — 100% in your browser, nothing uploaded.
How to find the BPM of any song
BPM — beats per minute — is just how many times you'd naturally tap your foot in sixty seconds. The fastest way to measure it is to tap along: press the TAP button or the spacebar in time with the beat, and this tool averages your last several taps into a live tempo reading. Eight taps is plenty; the more you tap, the steadier the number gets. If you'd rather not tap, switch to Detect from file, drop in a WAV or MP3, and the tool finds the rhythmic pulse automatically and reports a BPM with a confidence score.
Because everything runs inside your browser with the Web Audio API, it works on files no online database has ever seen — unreleased demos, private stems, sample-pack loops and AI-generated tracks that lookup sites like Tunebat simply can't identify. Detection sometimes locks onto a pulse an octave away, so a 140 BPM track can read as 70; that's why we always show the half-time and double-time alternates next to the main number. Pick whichever matches how you count the groove, then set your DAW, drum machine or delay to match.

FAQ
How do I find the BPM of a song?
Tap the beat — hit the TAP button or the spacebar in time with the music for about eight beats and the tempo appears live. Or switch to file mode, drop the audio in, and it detects the BPM automatically with a confidence score and half/double-time alternates.
Does this upload my audio file?
No. Dropped files are decoded and analysed entirely in your browser with the Web Audio API — nothing is sent anywhere. That's why it works on unreleased demos, private stems and AI-generated tracks that database lookups can't match.
Why does it show half or double the BPM I expected?
Tempo detection can lock onto a pulse an octave away, so a 140 BPM track can read as 70 and a 90 BPM track as 180. The tool always lists the half-time (÷2) and double-time (×2) alternates so you can pick the one that fits how you count the beat.
