# this is the harmony engine, adding layers of extra vocals # to my voice in real—time.# the program first recognises which note i am singing, and then adds layers based on music theory or even user input. the company who makes this are behind autotune, which is everywhere in pop music, and if you have ever listened to a billie eilish song, you have already heard the harmony engine used to great effect. # what do you want from me, why don�*t you run from me... that sounds familiar. i didn�*t realise that was technology. you analyse the formant of the pitch you�*re singing at, then you slice of your head, you transpose the pitch, and then put the head back on. laughter. that is really how it works in a kind of silly sort of explanation. the new product, auto tune slice has only been out a week.
