Implementation of MPEG-4 Audio Nodes in an Interactive Virtual 3D Environment
We show how to use MPEG-4 audio nodes in an interactive virtual 3D scenery to improve scene realism in the auditory domain. Therefore we extend the Virtual Reality Modeling Language (VRML) because of it's similarity to the MPEG-4 scene description. In addition to the implementation of localized sound sources in the scenery, the effect of acoustic obstruction is discussed. Several possibilities for the detection of obstruction are presented. The results demonstrate the capabilities of MPEG-4 audio scene description and thus point out the need for a fully compliant MPEG-4 player to utilize the complete functionality of this standard.
