Basics of Digital Waveguide Modeling

Digital waveguide synthesis models are computational physical models for certain classes of musical instruments (string, winds, brasses, etc.) which are made up of delay lines, digital filters, and often nonlinear elements.

Digital waveguide models typically share the following characteristics:

• Sampled acoustic traveling waves
• Follow geometry and physical properties of a desired acoustic system
• Efficient for nearly lossless distributed wave media
  (strings, tubes, rods, membranes, plates, vocal tract, )
• Losses and dispersion are consolidated at sparse points along each waveguide
