Abstract

Most standard scene description languages include a sound description and factorize common elements needed by the description of visual and auditory information. Both aspects are described with the same coordinate system for example. However, as soon as a dynamic description or external data are required, this benefit is lost and all the glue must be done by a programming solution that does not fit designers or authors usual skills. In this paper we address this problem and propose a solution to give back to designers the bigger role even when the scene is dynamic or based on procedural synthesizers. This solution is based on the COLLADA file format in which we have added sound support, scripting capabilities and external extensions. The use of this augmented COLLADA language is illustrated through the creation of a dynamic urban soundscape.
