BPM (beats per minute) is the standard musical tempo metric. Knowing the exact BPM of a track is essential for beatmatching in DJing, for syncing samples in music production, and for playlist analysis. This tool analyzes the file locally using energy envelope autocorrelation — without sending any data to servers.

Open full toolHow is BPM measured automatically?
- The algorithm converts audio to mono and computes the energy envelope over time. Autocorrelation of that envelope finds the dominant periodicity — the period that repeats most consistently — and converts it to BPM. This is the same principle used by professional tools like Ableton Live and rekordbox for automatic BPM analysis.

Full tool FAQ
BPM (Beats Per Minute) is the unit of measurement for musical tempo — how many beats occur per minute. 120 BPM means 2 beats per second. It is fundamental for syncing loops in music production, aligning video cuts to music, configuring delay and arpeggiators in synthesizers, and beatmatching in DJing.
Frequently asked questions
Is the BPM result exact?
For music with constant tempo and clear beat (electronic, hip-hop, rock), accuracy is generally ±1–2 BPM. For live recordings, jazz with heavy swing, or complex rhythms, the result may diverge more. The confidence score indicates measurement quality.
Does this page replace official or professional review?
No. It helps explain the scenario and use the tool more safely, but real decisions should consider official sources, full context and qualified guidance when needed.
