Efficient physics-based sound synthesis of the piano using DSP methods

In the recent years, digital waveguide modeling of musical instruments has proven to be an effective tool for sound synthesis purposes, but some practical questions still have remained unanswered. In this paper a new equivalent structure of the digital waveguide for string synthesis is presented. This structure can be used for highly efficient modeling of beating and two-stage decay, an important characteristic of the piano sound. The complexity of the traditional structure can be reduced by replacing one of the string models with a resonator bank.
