I was listening to the mars volta recently, and i was struck by how loud the mastering was. i looked at the waveform and almost entire songs were clipping, yet it doesnt sound terrible. im sure if i were to try something similar, it would turn out horribly. i'm not saying that louder is better like record companies seem to believe. i've seen godspeed you black emperor have entire 5 minute sections (motherfucker=redeemer) be clipping, and yet it sounds great. they mixed it themselves and it has plenty of dynamics; they didnt let whoever mastered it squash it, it seems. anyway.. how is this done without making things sound horrible?
