Rendering MPEG-4 AABIFS content through a low-level cross-platform 3D audio API

The advanced audio binary interface for scene description of the MPEG-4 standard version 2 offers two acoustic models, one perceptual and the other physical, for the description and rendering of virtual audio environments. In order to facilitate the implementation of an MPEG-4 AABIFS renderer, we describe translation strategies to a cross-platform lower-level rendering model, EAX 4.0. This environmental audio API is here used to extend OpenAL, a cross-platform 3D audio API through which the audio is streamed. A rendering architecture for the control and playback of the AABIFS stream is presented.
