Abstract
Different methods have been proposed for digital sound synthesis by physical modeling. Since musical instru- ments may consist of several components with quite different physical nature, there is no single best modeling paradigm. Choosing the optimal model for each component requires a common interconnection strategy, which leads to a computable algorithm with faithful sound reproduction. This contribution describes such an interconnection strategy on the basis of the wave digital principle. Examples are given for string, membrane, and brass instruments. I. I NTRODUCTION Digital sound synthesis by physical modeling attempts to model the physical sound production process itself rather than only to recreate a certain waveform. A number of dif- ferent techniques have been developed so far. However, since many musical instruments consist of different components with different physical nature, there is no single best meth od for physical modeling. Choosing the optimal model for each component requires a common interconnection strategy, which leads to a meaningful discrete-time approximation of the total system. Such a strategy is provided by the well-known wave digital principle. The use of wave variables for the interconnection network avoids the formation of delay free loops and yields computable algorithms. This contribution describes the wave digital principle as a starting point for the more general id ea of block-based physical modeling. It has been developed as a joint effort by the consortium of the European project ALMA (1). Section II presents the classical wave digital principle for lumped and distributed parameter networks. Section III introduces block-based modeling with examples for string and membrane instruments in Section III-B, and brass instruments in Section III-C.
