1) Everything was mastered by Chris Bellman at Bernie Grundman Mastering. 24 bit 44.1K and 24 bit 16K mastered at a higher level for streaming (Spotify, etc). 24 bit 44.1K specifically mastered for iTunes (MFiT) -for Apple streaming. Apple now tells us that they can accept 2496 files, but they were too late in telling us for this project, and, at this time, Apple has no facility for streaming at that rate. Happy to consider that for the future!
The CD was mastered at a LOWER level than the original (for more dynamic range). There is another big project that I worked on this year that will come out on CD at a lower level as well. This is how I'm going to do things from now on, in large part from all the comments on the Hoffman Forums about dynamic range. IMO, CD is now it's own ecosystem, and those that are willing to pay for physical media should be rewarded with good packaging and good sound.
24 bit 96K format was mastered at even lower level (most dynamic range) and available for those that currently offer hi-res streaming (i.e.Tidal) and for digital downloads (i.e. HD Tracks).
