Audio Mastering: Essential Practices is now on the shelves of the internet near you. I sincerely hope some find it interesting and informative. I've attempted to give some perspective on what mastering is (at least as I see it). In my mind it isn't mysterious, or magical, but it IS a discipline that requires practice and understanding. This is my contribution to help point people in the direction towards all the above.
If you are willing, I would be pleased to have reviews posted on Amazon and elsewhere and happy to receive feedback.
