AB  - A digital reverberator modeled after the scattering of acoustic waves among trees in an idealized forest is presented. Termed ``treeverb,' the technique simulates forest acoustics using a network of digital waveguides, with bi-directional delay lines connecting trees represented by multi-port scattering junctions. The reverberator is designed by selecting tree locations and diameters, with waveguide delays determined by inter-tree distances, and scattering filters fixed according to tree-to-tree angles and trunk diameters. The scattering is modeled as that of plane waves normally incident on a rigid cylinder, and a simple low-order scattering filter model is presented. Small forests are seen to yield dense, gated reverb-like impulse responses.
