摘要
Wave Field Synthesis (WFS) of a moving sound source is of great importance in the aspect of creating dynamic sound scenes. The article presents the strict mathematical derivation of WFS driving functions for an acoustic monopole, moving in an arbitrary direction with a uniform velocity. The derivation utilizes the traditional WFS theory for linear secondary source distributions by adapting the stationary phase approximation to moving source dynamics. By obtaining a purely time domain solution, the present approach provides a more correct synthesis compared to previous solutions for the problem and overcomes the drawbacks of the authors' previous methods (e.g., their great computational complexity).
