The Third Edition includes four hundred new entries, such as AAC (advanced audio coding), lip synch, metadata, MP3, and satellite radio. Every term from previous editions has been reconsidered and often rewritten. Guest entries are by Dennis Bohn, cofounder and head of research and development at Rane Corporation, and film sound expert Larry Blake, whose credits include Erin Brockovich and Ocean's Eleven. The appendixes--tutorials that gather a lifetime's worth of experience in acoustics--include both new and greatly expanded articles.

Each definition, from absolute pitch to zero reference, is actually a mini-article with concise yet thorough explanations that are easy for nonspecialists to understand." -Music Educators Journal
