HoRNet SongKey is a key detector thatworks in real time analyzing a polyphonic audio stream (usually a song) and, thanks to some advanced artificial intelligence algorithms, identifies in which key the song is composed.

Since the brain inside SongKey tries to "guess" the correct key, the three more probable keys are shown together with a confidence level for each key. SongKey also displays a "note profile" for the song showing which notes are played the most.

A spokesperson told us, "SongKey is very useful in those situation in which you don't have an instrument at hand to find out the key of a song you are working on or if you are a DJ and want to make a mash up but you don't know in which key a song is written."
