An Approach to Discrete-Time Modelling Auralization for Wave Field Synthesis Applications
In virtual room acoustics, the goal is to create the illusion of three-dimensional natural and realistic sound scenes. Accuracy of numerical methods in discrete-time domain provides an explicit and practical way to synthesize impulsive responses of virtual rooms, specially in low frequency applications. On the other hand, advanced multichannel sound system such as Wave Field Synthesis (WFS) allows to recreate spatial wider sound scenes of sources after being convolved with extrapolated impulsive responses. In this paper, the use of synthesized impulsive responses obtained by means of finite-differences time domain method in auralization purposes using WFS reproduction system is proposed and discussed. This method provides a complete solution of sound field variables, which are necessary to obtain a proper set of impulsive responses. Some examples are shown and evaluated to illustrate its applicability for WFS requirements.
