The digital waveguide mesh is an extension of the one-dimensional digital waveguide technique. The mesh is used for simulation of twoand three-dimensional wave propagation in musical instruments and acoustic spaces. The rectangular digital waveguide mesh algorithm suffers from direction-dependent dispersion. By using the interpolated mesh, nearly uniform wave propagation characteristics are obtained in all directions. In this paper we show how the dispersion error of the interpolated mesh can… CONTINUE READING
