T10 - New Technologies for Up to 7.1 Channel Playback in Any Game Console Format

Geir Skaaden, Neural Audio Corp. - Kirkland, WA, USA

This tutorial investigates methods for increasing the number of audio channels in a gaming console beyond its current hardware limitations. The audio engine within a game is capable of creating a 360 8 environment, however, the console hardware uses only a few channels to represent this world. If home playback systems are commonly able to reproduce up to 7.1 channels, how do game developers increase the number of playback channels for a platform that is limited to 2 or 5 outputs? New encoding technologies make this possible. Descriptions of current methods will be made in addition to new console independent technologies that run within the game engine. Game content will be used to demonstrate the encode/decode process.
