Mastering for me is a necessary evil, and I have great respect for mastering engineers. Studio One seems like it takes some of the pain out of the process, and I have never seen a product offer such global control over the whole album/EP sound. As a person who enjoys listening to an album top to bottom, this seems like a totally natural way of working, and is closer in workflow to a Wavelab product than Pro Tools.
The video is produced by Graham Cochrone of The Recording Revolution, an excellent resource for all things recording. Although his main focus is the burgeoning home and project studio world, engineers and producers of all levels will find his incites useful and interesting.
