Ok....what's the deal with mastering? We just got our CD back from being mastered and I can't tell much diffrence between what we sent them and what we got back. But I know it's something that needs to be done. The only major diffrences I've noticed so far is that they shortend some of song spacing and in one song there is now a loud hiss. Alot of the songs sound "brighter" and the vocals are louder it seems, but that Isn't really what we wanted....we mixed it the way we liked it, but now it's really bright. What is actually done when a CD is mastered? Just curious....even though it's a little diffrent, the CD still is pretty GOOD.
