Abstract
This paper describes how SMIL can be extended to support 3D audio in a similar fashion than AABIFS does it for MPEG-4. The SMIL 2D layout is extended with an extra dimension to support a 3D space. New audio elements are positioned in the 3D space, whilst a listener element defines a listening point. Similarly to AABIFS perceptual modeling approach, an environment element describes environmental parameters for audio elements. These extensions enable interactive 3D audio capabilities in SMIL. In addition, any XML based rendering language could be extended with 3D audio capabilities by using a similar approach.
