Synthesis of directional sources using wave field synthesis, possibilities, and limitations

摘要: The synthesis of directional sources using wave field is described. proposed formulation relies on an ensemble elementary directivity functions based a subset spherical harmonics. These can be combined to create and manipulate characteristics the synthesized virtual sources. WFS introduces artifacts in sound for both ideal real loudspeakers. partly compensated dedicated equalization techniques. A multichannel technique shown provide accurate results thus enabling manipulation with limited reconstruction artifacts. Applications control direct interaction listening room are discussed.
