Abstract:

This paper reviews past digital waveguide methods for reproducing non-linear "reed" excitations as well as introducing a new method incorporating reed dynamics. This model is based ou a mass-spring-damper system and a non-linear flow control mechanism. In this way, a more physical system is attained which provides better approximations to the control parameters of real musical instruments. Further, it is shown that this model of the reed can be modified to represent the lips of a brass player, and the similarities and differences between these two systems are briefly examined.
