BPM Finder
Tap tempo or detect a song's BPM
Tap along to any song: at least 4 taps.
Click the pad or press Space / T on each beat. It averages your last 12 taps and starts over after a 2-second pause.
Listen: if the clicks drift, try the other tempo above. Many songs can be felt at half or double time.

About the BPM Finder
Find the tempo of any song two ways. Tap along to the beat (with the pad, Space or T) and it averages your last taps and tells you how steady you are. Or upload an MP3, WAV, M4A or even a video, and it listens for the beat and works out the BPM on your device, suggesting the half- and double-time readings too, since many songs can be felt either way. Play the song back with a click track to check it lines up. Producers also get a table of delay and reverb times in milliseconds (straight, dotted and triplet) for the tempo.
- Choose Tap the beat and tap along, or Detect from a song and drop an audio file.
- Read the BPM; try the half or double time if it feels off.
- Play with the click track to confirm, and use the delay table for your effects.
Frequently asked
How accurate is automatic BPM detection?
For songs with a clear beat (pop, dance, hip-hop, rock) it is usually within 1 BPM. For rubato, ambient or classical music, tap along instead, because the tempo may not be steady.
Why does it say my song could be 70 or 140 BPM?
Many songs feel natural at half or double time. Both are correct readings of the same beat; pick the one that matches how you count it.
How do I calculate delay time from BPM?
A quarter-note delay is 60,000 ÷ BPM milliseconds: at 120 BPM that's 500 ms. The table works out every note value, plus dotted (×1.5) and triplet (×⅔) versions.
Is my song uploaded?
No. The file is analysed in your browser and never leaves your device.
