Abstract

This chapter presents DRA (Dynamic Resolution Adaptation) audio coding standard [97] as an example to illustrate how to integrate the technologies described in this book to create a practical audio coding algorithm. DRA algorithm has been approved by the Blu-ray Disc Association as part of its BD-ROM 2.3 specification [99] and by Chinese government as its national standard [100].
