How this works
  1. 1
    Drop in an audio file

    Pick an MP3, WAV or M4A of the track you want to analyse. Nothing leaves your browser.

  2. 2
    Hit detect

    We scan the waveform in your browser and estimate the tempo. Longer clips give steadier results.

  3. 3
    Read the BPM

    A single number appears. Use it in your DJ set, workout playlist or metronome practice.

Watch: song waveform → detected tempo
128 BPM
How this works

    Pick a track and we'll measure the gap between beats to guess the tempo. Works best on songs with a clear drum or bass pulse.
