Features

Audio BPM Detector is a free local tool that calculates the beats-per-minute tempo of any music track directly in your browser. Drag in an MP3, WAV, or FLAC file from your desktop or tap the tempo manually with a microphone or spacebar, and the analyzer will output a stable BPM reading plus beat-tap markers you can export to your DAW or video editor. Everything runs client-side — audio files never leave your device and are never uploaded, so unreleased tracks and commercial stems stay fully private.
