Abstract: Much w ork has been done in the eld of physical modelling in order to digitally simulate the propagation of acoustical plane waves in waveguides.In most of the work, the acoustical assumptions taken into account result in the linear behaviour of the waveguide; the acoustical wave speed can be considered as constant and independent from the local acoustical pressure.But for some wind instruments (e.g. the trombone), the acoustic pressure is so high that the linear assumption is no longer valid.In this case the model must include the nonlinear propagation.This paper presents a new nonlinear lter for simulating the nonlinear propagation in digital waveguides.
