Find the BPM of an audio track
Analyze tempo in the browser and compare plausible half-time or double-time readings. Use the result as a practical estimate, especially for songs with changing tempo.
Audio is analyzed locally in your browser; raw audio is not uploaded. Sign-in is requested only when you run the tool.

- 02
Let the browser analyze it
Tempo is estimated from repeating onset and beat patterns.
- 03
Check the musical feel
Decide whether the full, half-time, or double-time reading matches how you count the track.

Questions
What to know first
Is the BPM always exact?
No. Live timing, tempo changes, and weak percussion can reduce accuracy.
Why are half-time and double-time shown?
The same pulse can be counted at related speeds depending on genre and musical feel.
Does the audio leave my browser?
The manifest defines this as a browser-analysis tool; the page should disclose if implementation requirements ever change.
