TONART automatically determines the key signature of any monyphonic or polyphonic audio signal. Potential use cases include checking the key-compatibility of multiple songs in DJ software, and automatic metadata creation, such as ID-tags. One of TONART’s unique features is its ability to detect a signal’s tuning frequency or standard (concert) pitch.
In the latest TONART update, Version 3, the detection algorithm was completely redesigned. The result is a 50% improvement in key detection accuracy, positioning it firmly among the most advanced tools available today. Additionally, an Electronic Dance Music-optimized mode is tuned to detect less obvious keys more accurately. Finally, the tuning frequency detection is more reliable, and the API has been simplified.
