A program for full three-dimensional simulation of sound propagation in enclosures is presented which interfaces to a graphical interface for intuitive setup of complex simulation scenes. The simulation algorithm is based on the wave digital ¯ltering principle, allowing for arbitrary re°ection coe±cients at object boundaries and walls for realistic results. Simulation scenes are de¯ned in an object oriented way. As a graphical user interface to the simulation program a modeler front-end for a raytracing program is used. Simulation setups can thus be built by graphically placing objects in the scene. Being open source, the proposed modeler can easily be customized if required. Simulation results are shown for several example setups demonstrating the possibilities of our approach.
