Estimates based on audio analysis — always double-check by ear before the final master.
How to find the key and BPM of a song
- Drop any audio file (MP3, WAV, M4A, FLAC and more) onto the analyzer above, or click to browse.
- The analysis runs in your browser — the file is never uploaded to a server.
- Read the results: tempo in BPM, the musical key and scale, and the Camelot code for harmonic mixing.
- Double-check by ear before a final master — automatic detection is an estimate, and half/double-time tempos (e.g. 70 vs 140 BPM) are musically equivalent.
Preguntas frecuentes
Is this key and BPM finder really free?
Yes — it is completely free with no account needed. Analysis runs locally in your browser, so there is nothing to upload and no file-size fee.
What is a Camelot code?
The Camelot wheel maps every musical key to a number-letter code (like 8A or 5B) so DJs can mix harmonically: tracks one step apart on the wheel blend smoothly. Our guide to the Camelot wheel and harmonic mixing explains it in full.
Why does the BPM look doubled or halved?
Detection can lock onto half-time or double-time — 70 BPM and 140 BPM describe the same groove. Pick the value that matches how you count the track; our guide on finding the BPM of a song covers this.
Which audio formats are supported?
Any format your browser can decode: MP3, WAV, M4A/AAC, OGG and FLAC cover almost every file you will meet.
