Following the current trend of employing parametric enhancement tools for increased coding and spatial rendering efficiency, MPEG audio pursues a standardization activity on Spatial Audio Object Coding (SAOC) technology. The SAOC system extends the MPEG Surround standard by exploiting its coding 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, besides describing the basic SAOC architecture and the manifold of enhancement tools, this paper will focus on the relevance for gaming applications.
