Spatial audio coding - status and recent advances in parametric multi-channel audio coding

Spatial audio coding is the most recent parametric extension to waveform coding. This paper describes the ideas behind this technique, starting with a brief review of the basic concept of using parametric tools for waveform coder enhancement followed by a more detailed description of spatial audio coding. Some performance data and a report on activities of the ISO/MPEG standardization group in this field conclude this paper
