The finite difference time domain (fdtd) method has been and continues to be widely used as a computational room acoustic modeling technique. in that context, the method aims to numerically solve the wave equation in enclosed spaces. In this paper, we present a detailed study between different approaches to the parallelization of the fdtd method applied to room acoustics modelling, and we describe several optimization guidelines to improve the computation speed when using single precision and double precision floating point model data, nearly doubling the performance. This paper portrays the wavecloud project, an open source modeling framework designed with room acoustics simulation in mind. practical concerns such as computation time, handling arbitrary room geometries, and modeling directional sources and receivers are addressed and their current implementations in wavecloud are discussed.
