What you can do here
The audio analyzer estimates BPM, musical key and Camelot code from MP3 or WAV files. You can listen to the audio, check a result, adjust it and copy the values. A built-in synthetic example lets you try the workflow before selecting your own file.
Use Tap Tempo when you can hear a beat, Key from chords when you already know the chords, and BPM to ms to calculate tempo-synced delay times. The Camelot wheel helps you compare related keys.
An estimate you can check
Music can have more than one plausible tempo or tonal center. Sparse audio, changing arrangements and relative major and minor keys can make automatic analysis uncertain. Our tools show candidates rather than guarantee a single correct answer. They do not replace listening or a musician's judgment.
Our key guide and BPM guide explain how to check results, with synthetic listening examples. The practice walkthrough explains the analyzer's controls and limits.
Your files stay on your device
Audio analysis runs in your browser. Selecting a file does not upload the audio or its filename. Sharing a correction is a separate action; see the privacy notice for correction storage, analytics and planned advertising.
