I've been reading online and listening to audio examples of mastered song. Mastering to me has always been "just boost your volume and you'll be OK". But as I hear more examples, song seemed to be transformed from great to excellent. I've known to bounce to disk in pro-tools then make a new session and import that bounce to start mastering. Is this the industry standard or would a mastering house want my whole PT session to load up on their machines to master? This will be my first time to attempt proper mastering and even if I don't do too much I'd like to do it well. I guess I'm just looking for a starting point.
