- The digital waveguide mesh (DWM) is a multi-dimensional numerical simulation technique used to model vibrating objects capable of supporting acoustic wave propagation, with the result being sound output for excitation by a given stimulus. To date most DWM based simulations result in the static system impulse response for given initial and boundary value conditions. This method is often applied to room acoustics modelling problems, where the offline generation of impulse responses for computationally large or complex systems might be rendered in real-time using convolution based reverberation. More recently, work has explored how the DWM might be extended to allow dynamic variation and the possibility for real-time interactive sound synthesis. This paper introduces the basic DWM model and how it might be extended to include dynamic changes and user interaction as part of the simulation. Example applications that make use of this new dynamic DWM are explored including the synthesis of simple sound objects and the more complex problem of articulatory speech and singing synthesis based on a multi-dimensional simulation of the vocal tract.
