It's not the perfect solution, and there's still a bit of mystery around why the issue only happens to certain people, but it should at least provide us music nerds the tools we need to fix the problem for ourselves.

I'll make a short video when it comes out and have tested it a little.

I'M SO CONFUSED AAAAAA

There's a few clips of mine that are sped up, if anyone ever wants the raw files to look at for whatever reason let me know and I'll put them up.

Also I accidentally rendered this at 30fps. Yuck.
