How to Find a Song's BPM and Key for Free (No DAW Required)
How to get a song's BPM, musical key, and energy structure for free in your browser — no DAW, no manual tapping along to the beat.
The manual way to find a song's BPM is tapping along to the beat and letting an app average your taps — slow, and easy to throw off by one missed tap. The automatic way just reads the audio directly.

Read the result
BPM, musical key, an energy curve across the track, and segment structure (verse/chorus-style sections) come back automatically.
Why this matters beyond just knowing the number
BPM and key aren't just trivia — they're the inputs that determine what fits together. Matching a sample's key before layering it in, or picking a cut style that suits a song's actual tempo instead of guessing, both start with an accurate BPM/key read. See how to pick the right cut style for your song's genre for how BPM and genre map to a specific editing pace.
What "energy curve" and "segments" mean here
Energy curve is a read of how loud/intense the track is moment to moment — useful for spotting the drop or chorus at a glance. Segments are the track auto-divided into structural sections, so you can see where a chorus starts without scrubbing through the whole waveform by ear.
