Digital Waveguide Mesh for Room Acoustic Modeling

The two main approaches for room acoustic modeling are the wave-based and the ray-based techniques. In this paper we briefly overview the digital waveguide mesh method which is a wave-based model operating in the time domain. As a case study we show visualizations of edge diffraction modeled with the waveguide mesh technique. Some preliminary analysis of computational requirements for real-time auralizations are also presented, and the idea of frequency domain hybrid model is revisited.
