BPM Finder & Tempo Analyzer

Analyze your audio tracks instantly to detect their exact Beats Per Minute (BPM).

Online Song BPM Detector

Accurately measure the tempo of any music track or sound recording directly in your browser.

What is it?

The BPM Finder is an online tool that calculates the exact speed or tempo of a song measured in Beats Per Minute (BPM). It processes modern audio files such as .mp3, .wav, .m4a, .flac, .ogg, and .aac completely locally on your device without uploading anything to a server.

How to use it?

Simply select or drag and drop your sound file into the upload box. Our client-side audio engine will automatically process the audio buffer and display the detected BPM value within seconds. You can also listen to the track using the built-in waveform player to verify the tempo match.

Who uses this tool?

DJs use it for harmonic set transitions and beatmatching, choreographers and fitness instructors use it to align workout routines to music rhythm, and music producers use it to quickly check project tempos.
