Free BPM Finder — Detect Tempo of Any Song
SnipSound's BPM finder analyzes any audio file you drop into it and tells you the tempo (beats per minute) in seconds. It supports MP3, WAV, OGG, FLAC, AAC, and M4A. The whole calculation runs in your browser using the Web Audio API and a beat-detection algorithm — nothing is uploaded to a server.
How It Works
The detector reads the audio's energy envelope, finds peaks consistent with a steady beat, then estimates BPM by measuring the intervals between those peaks. You see the detected tempo, a confidence score, and visual beat markers laid over the waveform. If the detected BPM is half or double the real tempo (a common ambiguity in detection), you can manually halve or double it with one click.
Why You Need a BPM Finder
Common uses: matching a song to a treadmill or cycling workout pace, finding tracks that mix well with another song (DJs match BPMs to blend tracks), syncing music to a video edit's cut timing, choosing a tempo-appropriate backing track for a podcast intro, or analyzing your own productions to confirm the tempo is what you intended.
