Abstract

The MPEG-4 standard provides a complete framework for hybrid coding of natural and structured sound information that permits the description of complete spatial environments by a low amount of data. A new platform, based on a virtual DSP, has been developed to optimize the MPEG decoding and pre-processing interface to feed an array of loudspeakers rendering spatial Audio by Wave Field Synthesis. The virtual DSP has an instruction set adapted to MPEG-4 advanced audio features on superscalar processors.
