- Drop in an audio file or click to choose one — MP3, WAV, M4A, OGG, or FLAC. It stays on your device and is never uploaded.
- Wait a moment while it analyzes the beat and shows the tempo in BPM, with a classical tempo marking and a confidence rating.
- If the reading feels off, tap a half-time or double-time alternative — detection can lock onto half or double the real beat.
- Option 1 — Hear it with a click: play the song with a metronome click on top. If the click stays locked to the beat, the BPM is right.
- Option 2 — Tap it yourself: play the song without the click and tap the pad along to the beat, then compare your tapped BPM to the detected one.
- Copy the BPM and use it in the Metronome or Drum Tracks to practice the song at the right speed.
About This Online BPM Finder
Guitar Tool Hub's free BPM finder (also called a music tempo finder, BPM counter, or BPM detector) measures the tempo of any song or audio file right in your browser. Drop in an MP3, WAV, M4A, OGG, or FLAC and it analyzes the beat to report the tempo in beats per minute, along with a confidence rating and half-time / double-time alternatives. Play your track back with a metronome click layered on top to confirm the reading by ear. Because all analysis happens locally on your device, nothing is ever uploaded — and it works best on tracks with a clear, steady beat.

Frequently Asked Questions
Upload the song (or any audio file) to the BPM finder and it analyzes the beat to report the tempo in beats per minute automatically. You don't need to tap along. Once it shows a result, press play to hear a metronome click layered over the track so you can confirm the tempo matches by ear.
For music with a clear, steady beat — anything with drums or a strong rhythmic pulse — detection is usually accurate to within a beat per minute. Each result comes with a confidence rating. Tracks with rubato, lots of tempo changes, or sparse rhythm (a solo fingerpicked guitar, for example) are harder to measure and may need the half-time/double-time correction.
Yes. Below the result there's a tap pad — play the song and tap the button in time with the beat, and it shows the tempo you tapped next to the detected BPM so you can compare the two. If your tapped tempo lines up with the half-time or double-time option instead, that's a quick way to confirm which reading is right.
Tempo detection finds the strongest periodic pulse, which can be the half-beat or the full measure rather than the quarter-note beat. That's why the tool offers half-time and double-time alternatives. If the click feels twice as fast or twice as slow as the song, pick the alternative that lines up.
No. The file is decoded and analyzed entirely in your browser using the Web Audio API. Nothing is sent anywhere, so it stays private and works even on large files without an upload wait.
You can load MP3, WAV, M4A, OGG, FLAC, and most common audio files your browser can decode.
The BPM Finder measures the tempo of an existing recording — you give it a file and it tells you the BPM. The Metronome does the opposite: you set a BPM and it produces a steady click to practice along to. Once you've detected a song's tempo here, you can dial that number into the Metronome to practice at the same speed.
