Following the current trend of employing parametric enhancement tools for increasing coding and spatial rendering efficiency, the MPEG audio group performs the standardization activities on Spatial Audio Object Coding (SAOC) technology. The SAOC system extends the MPEG Surround standard by exploiting its rendering capability and decoding efficiency. Moreover, the SAOC technology introduces user-controllable rendering functionality together with flexible choice of various playback configurations. These aspects are of potential interest for a large range of gaming applications that will benefit from the efficient coding and interactive rendering. Although SAOC targets many different application scenarios, this paper will describe the basic SAOC architecture and the manifold of enhancement tools, with a specific focus on the relevance for gaming applications.
