I've been using Sound Forge for about ten years, for a very specific, technical kind of editing. I learned just the aspects of the software that suited my work, and nothing more. Now I want to gain a FULL understanding, as inexpensively as possible.
I'm about a quarter of the way through this book and find it to be EXCEPTIONALLY USEFUL/HELPFUL. The author explains the concept and use of all aspects of the program. Only slight allowance needs to be made for the fact that I'm using version 9, when the book actually is written for the prior version 8.
Amazon's price is excellent, well below the publisher's price and generally less than competing onine resellers. And what's better than prompt FREE delivery with a 30-day return policy? Buy this book and keep it handy. It is showing me in clear, understandable terms how vastly capable Sound Forge really is (after all my years of using the software...duh)
