Well, masters are done, approved, and delivered to CM. Jens did a fantastic job on the mastering, he took what I did and made it all sound significantly more exciting and punchy...totally appropriate decision-making on his behalf and a very desirable outcome. I've mastered my own projects plenty of times when working with smaller bands who don't have a budget for serious mastering, and I can get by like that when there's no other option, but it really is the coolest thing being able to hand off a project to someone trustworthy and let them be the final set of ears.
I'm sure at some point in the future I'll be able to upload a short clip from the album, like I did with 7H7E...a 24-bit/44.1 unmastered WAV, and then the same clip as a 16-bit/44.1 mastered WAV, and you guys will be able to hear the difference for yourselves. I would say that the difference between mastered and unmastered this time around is definitely more noticeable than it was for 7H7E, which probably has a lot to do with the fact he actually used compression in the chain this time (and didn't for 7H7E), but I can't reiterate enough how much I love the outcome!
