Audition apparently seems to be some kind of unwanted stepchild of Adobe, based on the scarcity of resources Adobe seems to have dedicated to it. I bought this book based on other positive experiences with the "Visual Quickstart Guide" series, but as another reviewer states, this book barely covers what should essentially be in a basic user's manual. There is little if any detail, very few case-study example, and some significant holes in the instructions.
Example: in the "Using Cues" section - there is a section "to list and edit your cues," to "move cues" and to "delete cues"...but it says nothing about creating a cue to start with. These types of omissions can drive beginners insane, and signals some pretty bad editing.
Further, abstract explanations of sounds (or worse, how sounds work) are nearly useless. This book badly needs an accompanying cd. Five seconds of actual audio can teach more that fifty pages of words. Avoid this book.
