The full walkthrough
How to find the BPM of a song
Drop it or paste a link
Drop an MP3, WAV or video, or paste a YouTube link in the bar above.
Read the BPM
The BPM, key and Camelot code appear in seconds. A full song takes about 8 seconds.
Check it by ear
If the song feels twice as fast or slow as the number, the real tempo is double or half. Tap along on the BPM Tapper to confirm.
When the BPM looks half or double
Most wrong readings, from any BPM finder, are exactly half or double the tempo you hear. Both numbers describe the same beat, so pick the one your genre uses.
| If the result shows | Try |
|---|---|
| 70 for a trap or dubstep track | 140 |
| 87 for drum and bass | 174 |
| 180 for a slow hip hop beat | 90 |
| A number that feels right when you tap | Keep it |
DJ software often counts the same song at half or double. Use the number that matches the rest of your library.
