Tap the beat, get the BPM

The Fastest Way to Read a Tempo — Just Tap

Sometimes you don’t have the audio file — the song’s on the radio, playing across the room, or just looping in your head — and you still need to know its tempo. A tap-tempo counter is the oldest trick for that: tap along to the beat and let the math turn your rhythm into a number. This one does it instantly, right in your browser, with nothing to upload.

Steady, not jumpy

A naive tapper lurches on every stray tap. This one keeps a rolling average of your most recent taps, so the reading settles as you go and one off-beat tap barely moves it. Pause for a couple of seconds and it starts a fresh count automatically — perfect for checking one song after another. Tap the pad or press the Space bar; Escape resets.

Nothing to upload, ever

Because it measures your taps rather than an audio file, there’s no upload, no decoding, and no waiting — and it keeps working with your connection off. It’s the quickest read when you have the beat but not the file.

When you do have the file

If you’ve got the actual track, the BPM detector reads the tempo, key, and Camelot code from the file automatically — no tapping. And once you know the number, the BPM changer retempos a track to it, while the online audio editor handles key changes, trims, and cleanup.
