ABSTRACT
In audio-graphic scenes, visual and audio modalities are synchronized in time and space, and their behaviour is determined by a common process. We present here a novel way of modeling audio-graphic content for interactive 3D scenes with the concept of sound processes and their activation through 2D or 3D profiles. Many 3D applications today support both graphical and audio effects to provide a more realistic user experience; however a common model and interchange format for interactive audio-graphic scenes is still lacking. X3D is one of the most promising formats for 3D scene representation. It is extensible and supports simple spatial audio representation and almost all basic and advanced 3D computer graphics techniques. We therefore propose an extension of the X3D standard to represent the sound process and activation profile model for providing a rich audio-graphic description in X3D.
