How accurate is the BPM estimate?

It's generally accurate for music with a clear, consistent beat — tracks with irregular rhythm or heavy tempo changes are harder to estimate precisely.

Can it detect BPM for a track with no drums?

It analyzes the overall rhythmic pattern in the audio, not just drum hits, so it can often still estimate tempo from other rhythmic elements, though accuracy is generally best with a clear beat.

Why would I need to know a track's BPM?

Matching tempo for DJ mixing, syncing music to video edits, or setting a workout playlist to a consistent pace are the most common reasons.

Does Audio BPM Detector upload my files to a server?

No. Audio BPM Detector runs entirely in your browser using on-device processing, your files never leave your device.

About this tool

Matching two tracks' tempos for a DJ mix, or just wanting to know a song's BPM for practice or reference, usually means tapping along to the beat by hand and doing the math, or trusting whatever a music app happens to display. This tool estimates a track's tempo directly from its audio, giving you a BPM figure without manual tapping or needing the track's metadata to already include it.
