Quick answer
How does a BPM key finder work?
A BPM key finder reads an audio file and estimates its tempo and musical key. Load a song above and you get the BPM with half- and double-time options, the key, its Camelot code and the relative key, usually in seconds. It listens to up to 90 seconds from the middle of the track and runs on your device, so the file is never uploaded. The results are estimates, so confirm the tempo by tapping along.

Found the key and BPM of your reference? Make an original track to match.
- BPM
- Beats per minute. Half/double are the same groove felt differently.
- Key
- The home note and scale, e.g. A minor.
- Camelot
- DJ notation: same number or ±1 mixes harmonically.
- Relative key
- Shares the same notes — C major ↔ A minor.
- Confidence bar
- Low = modal, atonal or key-changing music.
A minor, 124
Original deep house instrumental in A minor, 124 bpm, warm bass, soulful chords

Tips
Getting accurate BPM and key results
What helps the finder — and what confuses it.
Songs with steady drums give the most reliable BPM.
Rubato piano, live jazz and ambient pieces have no fixed tempo.
Songs that change key get one 'average' key.
If the key looks off, try the relative major/minor shown.
Tap along for 8+ beats to confirm the tempo by ear.

FAQ
BPM Key Finder questions
10 questions
How do I find the BPM and key of a song?
Load the audio file into the BPM key finder above. It estimates the tempo, key, Camelot code and relative key in your browser in a few seconds.
Link to this answerCan I paste a Spotify or YouTube link?
No. The finder only reads an audio file on your device. Use a file you own or have the rights to use. For a song you can only stream, tap along with the tap tempo tool to get the BPM.
Link to this answerDoes it work as an MP3 key finder?
Yes. MP3, WAV, M4A and OGG files usually work, up to 60 MB. Your browser decodes the file, so other formats may work too, depending on the browser.
Link to this answerHow do I find what key a song is in?
Use the finder, or by ear: find the note that feels like 'home' (usually the last bass note), then check whether the song sounds major (bright) or minor (darker).
Link to this answerIs the BPM and key finder free?
Yes — it's free, needs no sign-up, and runs on your device.
Link to this answerIs my song uploaded?
No. The analysis runs locally in your browser with Web Audio; the file never leaves your device.
Link to this answerWhy does it show half or double the BPM I expected?
Many grooves can be counted either way — trap and drill are often felt at half time. The finder shows both alternatives; use tap tempo to decide.
Link to this answerWhat is the Camelot code?
A DJ notation for keys on a wheel (1A–12B). Tracks with the same number, or one step away, usually mix harmonically.
Link to this answerHow accurate is it?
It's an estimate, and we haven't published an accuracy figure. Steady, drum-driven songs are most reliable; free-tempo, modal or key-changing music is harder for any detector. Check the BPM by tapping along and the key by ear before you rely on it.
Link to this answerWhy does another BPM key finder show a different result?
Tools listen to different parts of a song and use different methods. Ours reads up to 90 seconds from the middle. A half- or double-time answer, or the relative major or minor, is the most common difference, and both can be fair readings of the same track.

How the BPM key finder works
Two analyses run on a mono copy of up to 90 seconds from the middle of the track:
- Tempo — it measures how the spectrum jumps at each hit (spectral flux), then finds the repeating period with autocorrelation between 60 and 200 BPM. A real beat also lines up at 2×, 3× and 4× its period, so those are scored too, with a gentle pull towards 120 BPM.
- Key — it sums the energy of each note name between 55 Hz and 2 kHz (chroma) and compares that with standard major and minor key profiles (Krumhansl–Kessler).
- Camelot and relative key — looked up from the detected key.
- Confidence bar — shows how clearly the best key beat the runner-up. It applies to the key, not the BPM.
Accepted files and limits
The finder works on files, not links:
- File types — MP3, WAV, M4A and OGG usually work. Your browser does the decoding, so support for other formats depends on the browser.
- Size — up to 60 MB per file.
- Length — any length that fits the size limit, but only up to 90 seconds from the middle is analysed. An intro or outro in a different tempo won't count, and neither will a tempo change outside that part.
- Tempo — songs outside 60–200 BPM show up at half or double their tempo, which is why both alternatives are listed.
Camelot codes for every key
The number is the position on the wheel. A is minor and B is major. Tracks with the same number, or one number away with the same letter, usually mix well:
- 1A A♭ minor · 1B B major
- 2A E♭ minor · 2B F♯ major
- 3A B♭ minor · 3B C♯ major
- 4A F minor · 4B A♭ major
- 5A C minor · 5B E♭ major
- 6A G minor · 6B B♭ major
- 7A D minor · 7B F major
- 8A A minor · 8B C major
- 9A E minor · 9B G major
- 10A B minor · 10B D major
- 11A F♯ minor · 11B A major
- 12A C♯ minor · 12B E major
How accurate is a BPM key finder?
Every automatic finder gives an estimate, and that includes this one. We haven't run a formal accuracy test, so we don't quote a percentage. Two kinds of near miss are common: a tempo at half or double the one you feel, and the relative major or minor of the true key, which uses the same notes.
Steady drums give the most reliable BPM. Rubato piano, live recordings and ambient music may have no single tempo. Songs that change key get one average result, and modal or atonal music gives a low confidence bar. For a DJ set or a release, check the result by ear.
Using BPM and key
Common reasons to check:
- DJ mixing — match tempos and neighbouring Camelot keys.
- Sampling and remixing — know the key before you add parts.
- Practising — set a click track to the song's BPM.
- Making a matching track — generate an original at the same key and tempo.
