What is Song Key Finder?

Song Key Finder analyzes audio to detect its musical key and scale. Essential for DJs mixing harmonically, producers sampling tracks, and musicians learning songs by ear.

How to use

  1. Upload an audio file (MP3, WAV, OGG, FLAC) or record directly from your microphone
  2. Wait for the analysis to process the audio's pitch content and harmonic profile
  3. View the detected key, scale, BPM estimate, and Camelot notation for DJ mixing

Result

A DJ wants to mix two tracks harmonically. Upload the first track — it detects A minor (8A Camelot). Now you know compatible keys are 7A, 8A, 9A, or 8B for smooth transitions.
