ok, I've got all my final mixes ready to be burned on discs. What I need to know is...do I burn them as data files? they are 24 bit wave files. I know to burn them as Disc-at-Once. And what are ISRC codes...Do I need to write them down for the ME? (I read somewhere that I do). Also, I use Nero for burning my projects and am deciding to burn at 2x or 4x. So if someone can tell me what exactly I need to send in to the ME that would be appreciated. Bear with me, I'm new to all of this stuff and this is my first project being sent to the mastering plant. So I'm kinda clueless on what to do and what to send in. If anybody can give me the heads up in the right direction that would be appreciated.
