More Cowbell said: I am right, ask any professional audio engineer.
the point at which you normalize to is user definable, it doesnt have to be 0dbfs
there are times, especially when working with digital syetms, that it is not easier to set the gain going in. digital systems generally have very low system noise, but sound awful if you pass the systems headroom and clip.
your example of 60% has no relevance to anything. why is 60% something not to go other? also normalizing systems, in my experience, dont work as a %, they're most likely to give a peak level settin (possibly telling you how much of a db increase that entails)
some audio engineering experts will also tell you that a properly recorded track will never require eq or compression
its not, personal judgement (and depending on the programme material limiting) is used to have coherant volume. otherwise if you have a track that is heavily compressed rock, followed by a soft one vocal and acoustic track, the latter will appear incredibly loud
its best used at the mixing stage. if you need it at mastering, you're mix isnt good enough to bother with mastering.
you're a douche, ask anyone with common sense and a little recording knowledge. and your avatar is annoying.
