Didn't read the article but I'm almost certain it's dynamic range compression.

I don't know why this hasn't been standard in Every OS.

EDIT: NOPE! It's just an automatic gain control :/

Dynamic range compression is kind of the same thing as automatic gain control (well, automatic gain control is one way of describing how to implement dyanmic range compression). This github project implements a compressor, it says in the readme.
