[0002] Audio content has traditionally been created and stored in a channel-based format. As used herein, the term "audio channel" or "channel" refers to audio content, typically having a predefined physical location. For example, binaural, surround 5.1, surround 7.1, etc. are all channel-based formats for audio content. Recently, with technological developments in the multimedia industry, three-dimensional (3D) movie and television content has become more and more popular in theaters and homes. In order to create more immersive sound fields and precisely control individual audio elements independent of specific playback speaker configurations, many conventional multi-channel systems have been extended to support new formats that include both cha...
