@Aevisia Im really interested in this as a concept and I'd love to explore it, but I'm confused what's happening - does it simply pitch shift stuff up enough so that an A4 becomes 528Hz (or down enough so A4 becomes 432Hz) instead of 440Hz? This doesn't seem right since then a song with no "A" notes in it would lack the desired frequency -- so what is it doing?
@eg0n
I am not entirely sure either but it does seem to change the pitch. I watched a video on it yesterday comparing the three different frequencies, using what sounds like the same track. The pitch was different but each frequency displayed a different resonance. It's really interesting! https://m.youtube.com/watch?v=TroHq0VlP0k
