“…Rendering modules are associated with a group of loudspeakers. They get audio streams and "scene description parameters" as an input from a communication network [30]. The scene-description parameters contain data describing, for each source, its position and directivity characteristics.…”

“…A directivity manipulation and visualization interface is presented in Figure 21. For each virtual source, source position and directivity parameters are manipulated and transmitted to the communication network [30]. A visual representation of the synthesized directivity is displayed for each absolute degree next to the manipulated parameters.…”

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 virtual sources. The WFS formulation introduces artifacts in the synthesized sound field for both ideal and real loudspeakers. These artifacts can be partly compensated for using dedicated equalization techniques. A multichannel equalization technique is shown to provide accurate results thus enabling for the manipulation of directional sources with limited reconstruction artifacts. Applications of directional sources to the control of the direct sound field and the interaction with the listening room are discussed.
