Feature Request: Option to change pitch to either 432hz or 528hz? #133

Hi,

I would love to be able to change the pitch to either 432hz or 528hz system wide. Thank you!

This would require ahead-of-time analysis of what the source pitch is? It may not even be constant across a song, if it is an old one / captured from tape or vinyl with drift / microtonal / or just employs some "weird" effects or whatever. In general the transformation needed to solve for this is not really defined. I would say this is a very hard problem to do that in realtime.
