Williams comes across very knowledgeable in this presentation. His clear explanations make it really easy to learn the basics of Audition as well as audio editing and production. While he gets you to understand the concepts of audio editing and the use of best practices, I do wish that there would have been more do's and don'ts about audio production as well as a few sections that could have been more in depth. That said, I do think that if you are wanting to get into working with Auditon 3, want to learn more about audio engineering and audio production in general then I can easily recommend Audition 3 Essential Training.
You can get Audition 3 Essential Training two ways. One is as a DVD training package Audition 3 Essential Training and the other is part of the online training experience at Lynda.com. The DVD Training Package is $99.95 USD and includes Audition 3 Essential Training as well as containing everything you need.
