A lot depends on the type of music you have recorded. What is it, and how many mixdown tracks? What instruments, vocals, etc. Any effects added to the tracks already? Please reply, and I will try to help. The most important question is, though, is anything wrong with it before mastering, or is it just fine as is? If nothing is wrong, don't screw it up. If you can identify the problems, you are well on your way to fixing them. Yes, big studios have lots of expensive gear and talented, trained people. Home recordists often do not, an are required to muddle through as best they can. I mastered my CD by listening to it through regular old living room speakers. It seems to sound great on all other systems I've tried it on. Lots of compliments from the people who bought it, even if it's not in the same league as the pros. Then too, some of the "pro" stuff sounds like over-processed crap to my ears. Matter of opinion. Al
