Abstract


The Digital Wave Guide (DWG) method is one of the most popular techniques for digital sound synthesis via physical modeling. Due to the inherent solution of the wave equation by the structure of the DWG method, it provides a highly efficient algorithm for typ ical physical modeling problems. In this paper it will be shown, that it is possible to use this efficient structure for any existing linear sound synthesis algorithm. By a consequent description of discrete implementations with State Space Structures (SSSs), suit able linear state space transformations can be used to achieve the typical DWG structure from any given system. The proposed ap proach is demonstrated with two case studies, where a modal solu tion achieved with the Functional Transformation Method (FTM) is transformed to a DWG implementation. In the first example the solution of the lossless wave equation is transformed to a DWG structure, yielding an arbitrary size fractional delay filter. In an other example a more elaborated model with dispersion and damp ing terms is transformed, resulting in a DWG model with parame ter morphing features.
