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.
