Using the proposed software toolbox, a designer can visualize sound waves propagating through a space. This allows for prototyping low-frequency correction systems. This software tool is based on a finite-difference time-domain algorithm. Small enclosed spaces have wildly varying responses even within a small listening area. The relationship between room mode distribution and room obstacles can readily be examined. The flexible nature of the toolbox enables accurate modeling from small-room acoustics to large-scale sound reinforcement.
