Straight talk

It reads the track well. It doesn't replace your ear.

Relative major and minor share the same notes, so a name is sometimes a coin toss. Keyplate shows its work and leaves the final call to you.

What it does

  • Key and tempo in about half a second, fully offline.
  • The Camelot code and the keys it mixes with.
  • Three key profiles vote, and it shows how sure it is.
  • Chord voicings as a real .mid at the detected tempo.

What it won't do

  • Always split relative major from minor. Trust the one that feels like home.
  • Nail tempo on sparse material. It can land on half or double time.
  • Do well on atonal, percussion-only, or heavily detuned audio.
  • Make the call for you. Your ear stays in charge.

Reads wav, flac, ogg and aiff natively; mp3 through your system or ffmpeg.
