Mastering Audio. The Art and the Science Bob Katz
Publisher: Focal Press

In Bob Katz book Mastering Audio: The Art and the Science there is a brief section that describes the process of upward expansion and describes the DBX 117 as the very first commercially available unit. If the project is going to a mastering engineer, bounce at the session settings and let the ME do any SRC or bit depth change at his end. (2003) Mastering Audio: the Art and the Science, Oxford: Focal. Mastering Audio, the art and the science. (2001) Music Engineering, Oxford: Newnes. This is an amazing book on audio You can find it on Amazon: http://www.amazon.com/Mastering-Audio-The-Art-Science/dp/0240808371/. I enjoyed greatly "ReaMix: Breaking the Barriers with REAPER", of Geoffrey Francis, aka nicholas. Many mastering engineers have heard of or read the book "Mastering Audio: The Art of the Science" by Bob Katz. You should also own Bob Katz's book “Mastering Audio, the Art and the Science.” While Katz often gets off onto technical, beard-y discussions of jitter and compressor knees, his knowledge is still pretty indispensable. Mastering Audio: The Art and the Science by Bob Katz. "Mastering Audio, the art and the science", Bob Katz, Focal Press, 2002. (2012) Music Technology, Cambridge: Cambridge University Press. I would highly recommend the book "Bob Katz Mastering Audio The Art and The Science" (http://www.soundonsound.com/sos/oct0es/bobkatz.htm).
