Book excerpt: Practical Art of Motion Picture Sound, 4th edition relies on the professional experience of the author and other top sound craftspeople to provide a comprehensive explanation of film sound, including mixing, dubbing, workflow, budgeting, and digital audio techniques. Practically grounded with real-world stories from the trenches throughout, the book also provides relevant technical data, as well as an appreciation of all the processes involved in creating optimal motion picture sound. New to this edition are exclusive sound artist lessons from the field (including 2 new production cases studies), including insight from craftspeople who have worked on the latest Harry Potter and Batman films. All technological changes have been updated to reflect the most current systems. **Please visit the book's website, www.focalpress.com/cw/yewdall to download the Yewdall Sound FX Library.**
