Convention Paper

Coding of Spatial Audio Compatible with Different Playback Formats

Authors: Faller, Christof

AES Convention 117 · Paper 6187 · October 2004

Abstract

Recently, various schemes were proposed for parametric coding of stereo and multi-channel audio signals. Binaural Cue Coding (BCC) is such a technique. It represents multi-channel audio signals as a single downmixed channel plus a small amount of side information. BCC can be applied to mono and stereo backwards compatible coding of multi-channel audio signals. In this paper, we propose a general paradigm for BCC with multiple transmission channels and show how this can be applied not only to bridging between mono/stereo and multi-channel surround but also to bridging between different multi-channel surround formats.
