for some reason the loudness variable... normalises? (im not sure help me out plz) Over time. so quiet bit will be big and then eventually loud bit will be small (ok now i dont think so) start all sounds can also be used to cycle through songs. for pc i recommend around volume 30 to 40. background noises will interfere with the equaliser.
or is it equaliser? credit to creo, hinkik, some random guy (insane drop) and waterflame. possibly others.
