RenderAIR — Room Acoustics Simulation Using a Hybrid Digital Waveguide Mesh Approach
The digital waveguide mesh (DWM) is a numerical simulation technique used to model signal propagation through a regular grid of spatio-temporal sampling points, and has been demonstrated as appropriate for modelling the acoustics of an enclosed space, particularly at low frequencies. The RenderAIR DWM application allows intuitive definition of parameters associated with geometry, boundary surface, and source/receiver parameters, required to generate spatially encoded Room Impulse Responses (RIRs). In this paper the expectations and limitations of DWM-based room acoustics modelling are explored through the use of the RenderAIR application in a number of situations. ISO3382 metrics are used as the main benchmark for the results obtained, which compare well with both real-world measurements and more traditional geometric acoustic approaches.
