The Vocuno BPM Detector finds the tempo of any audio file directly in your browser. There are no server uploads — analysis runs locally using the Web Audio API with onset detection and autocorrelation algorithms. It works with any genre and any type of audio, from full tracks to short loops and recorded samples.
Audio stays on your device — nothing is uploaded to Vocuno servers.

​
