I think mastering engineers do kind of guard their techniques.
I do.
And I feel that I've noticed various "known" engineers to be absent from these types of discussions. I sat in recently with Brian Gardner and Bernie Grundman and watched them work. Brian hardly discussed his work but Bernie went on and on like a fugitive getting something off his chest. It was weird, he discussed his favorite coffee, told me about his early experiences and how he bacame popular.
BECAUSE HE WAS AN INNOVATOR!
Because, more or less, ME's untill then, cut records flat. If a producer wanted a brighter or fuller sound, they remixed. Bernie compressed, made moves, all the stuff we take for granted today.
Yeah, he showed me his UREI Passive EQ's with the custom attenuators, but what I learned was...GO INNOVATE, seperate from the herd.
Look around his room and see little in common with other facilities. Same with The Mastering Lab. They just went their own way and the world caught on.
Who cares about other peoples settings, beat their work with YOUR SETTINGS. No, its not the '50's anymore. Not the dawn of the golden age of record making. But I do believe innovation is still possible. It hasn't all been done yet.
