Sound in COLLADA

Abstract

Abstract. Standard or normalized file formats exist since many years to write/read/exchange 3D scene descriptions. However, these descriptions are mainly for visual contents. Options given for sound compositions of 3D scenes are either lacking or poor. In this paper, we propose to include rich sound descriptions in the COLLADA standard, a commonly used scene language. Our work relies on a research project, the goal of which is to define and develop a sound engine for virtual cities. In this context we have implemented and experimented a first version of sound descriptions in COLLADA.
