Synthesis of Directional Sources Using Wave Field Synthesis, Possibilities, and Limitations

The synthesis of directional sources using wave field synthesis is described. The proposed formulation relies on an ensemble of elementary directivity functions based on a subset of spherical harmonics. These can be combined to create and manipulate directivity characteristics of the synthesized vir...
