How to Use

  • Use local media file, audio or video, to detect the root key (scale) from it.
  • Hit 🧹 CLEAR to reset.

Please mind the Confidence level. Better with actual music or (with) singing.

Technique

To prevent memory leak, this application only takes the starting ~60 seconds of the signal. If the audio is shorter than that, well, then the entire duration will be analysed.
