Thanks Andrew - nice article form SoS as usual
Couple of things in relation to it. As I recall SoS never really indicated how involved they were in the process. By this I mean how much they actually sat and discussed with the ME what they wanted, nor provided a comparison track nor were present during the process. Basically if you don't get involved don't expect the ME to be a mind reader
Second bit, nice to see the comment about the need to level-match for comparisons. There are zillions of stories from MEs about clients who say the mastered track sounds 'worse' because the ME has taken the levels down to appropriate levels. Too many people record too hot and too many people have gotten used to recordings that are presented too loud
Bit of an odd comment about Metropolis where you can add ISRC codes. Would have thought any
ME would ask you to supply them or at least the info so that they can fill it in before starting work. Mastering isn't just about getting the sound right, its also about making sure the master is cd print/glass ready. Red book sort of springs to mind...
