BPM finder, explained
Drop a song to find its tempo in beats per minute, plus its musical key. Analyze a whole folder at once; the audio never leaves your device.
How the tempo is found
The finder listens for note and drum onsets, looks for the interval at which they repeat most strongly, and then lines a grid of beats up with the music to pin the tempo down to a tenth of a BPM.
Tempo is reported between 80 and 180 BPM, the range most DJ software uses. A song can feel like half or double that speed, so both are shown too: a 70 BPM trap beat appears as 140, with 70 listed as half time.
When the result looks wrong
Songs with a free tempo, long breakdowns or tempo changes have no single right answer. Check the result by ear with the tap tempo tool: tap along for a few bars and compare.
Why does it say 140 when my track feels like 70?
