What Key Detector does
The plugin works on complex material rather than single isolated notes, and it indicates the key even when the pitch of the source is off-tune. Detection runs on Waves Neural Networks, which the developer describes as the basis for precise key detection, and results are given as a root note and a scale such as major.
Once a key is found, a Transmit button sends it to all active instances of the related Waves plugins, namely Waves Tune Real-Time, Waves Tune, OVox and Waves Harmony v14. Those plugins need their latest v14 release to receive the key. Searches for Key Detector commonly pair the name with keygen, a working serial and torrent or magnet link.

- Full mix and sample analysis. The detector accepts complex audio files, from full mixes to multi-instrument samples, and reports the key of the material as a whole.
