Wave field synthesis allows ws the exact reproduction of sound fields if the requirements of its physical foundationare met. However, the practical realization imposes certain technical constraints. One of these is theapplication of loudspeaker arrays as an approximation to a spatially continuous source distribution. Theeffect of a finite spacing of the loudspeakers can be described as spatial sampling artifacts. This contributionderives a description of the spatial sampling process for planar linear and circular arrays, analyzes thesampling artifacts and discusses the conditions for preventing spatial aliasing. It furthermore introduces thereproduced aliasing-to-signal ratio as a measure for the energy of aliasing contributions.
