key & bpm finder

how the key and bpm finder works

Drop in wav, mp3, flac or m4a files and the analyzer reads the audio right in your browser to find the musical key, the tempo in bpm, and the matching Camelot code for harmonic mixing. Nothing is uploaded to a server, so your music stays private and there is no file limit.

Every result shows a confidence score and the next most likely keys, so ambiguous tracks are easy to double check. Results are saved on your device between visits and can be exported to CSV for your DJ library.
