Abstract

Geometric and wave-based acoustic algorithms have been shown as appropriate for the auralisation of room acoustic models. In particular they hold significant potential to be used in interactive virtual environments as a means of real-time sound rendering, with possible applications ranging from aiding architectural acoustic design to enhancing computer game audio. This paper presents a tool for developing acoustical scenes in Blender, an open source 3D development programme, based on 3D acoustic modelling using ray-tracing and/or FDTD methods. With the potential for real-time interaction and walk-through auralisation by means of the Blender Game Engine we demonstrate how Blender can be used as part of the acoustical design process.
