Through exploiting the human perception of spatial sound, “Spatial Audio Coding” technology enabled new ways of low bit-rate audio coding for multichannel signals. Following the finalization of the MPEG Surround specification, ISO/MPEG launched a follow-up standardization activity for bit-rate-efficient and backward compatible coding of several sound objects. On the receiving side, such a Spatial Audio Object Coding (SAOC) system renders the objects interactively into a sound scene on a reproduction setup of choice. The workshop reviews the ideas, principles, and prominent applications behind Spatial Audio Object Coding and reports on the status of the ongoing ISO/MPEG Audio standardization activities in this field. The benefits of the new approach will be highlighted and illustrated by means of real-time demonstrations.
