Response to original post:

This is the tutorial I linked on the github page: https://www.geeksforgeeks.org/how-to-install-ffmpeg-on-windows/
Which points to this download link: https://www.gyan.dev/ffmpeg/builds/ffmpeg-git-full.7z
Which I think is pretty legit as ffmpeg's website links to it.


Response to Edits:

They should work being where they were when it was downloaded, I don't know why you needed two copies. Perhaps I should rework how it finds rabbitsign and the key, seems to be a common problem.

Yeah it seems like the Github version is broken or at least the latest release is, or I downloaded the wrong file, because Gyan worked now. It seems to sound slightly better on-calc than my PC which is pretty cool. My adapter is damaged but if I hold it I can clearly hear the music very well.

This is a song I made last Summer but only a small portion of it. With my speakers and subwoofer the bass is insane lol.
