Spatial Aliasing Artifacts Produced by Linear and Circular Loudspeaker Arrays used for Wave Field Synthesis
Spatial sound reproduction systems with a high number of loudspeakers are increasingly being used. Wave field synthesis is a reproduction technique using a high number of densely placed loudspeakers (secondary sources). The underlying theory, however, assumes a continuous distribution of secondary sources. Loudspeakers placed at discrete positions imply a spatial sampling process that may lead ...
متن کاملSpatial Sampling Artifacts of Wave Field Synthesis for the Reproduction of Virtual Point Sources
Spatial sound reproduction systems with a large number of loudspeakers are increasingly being used. Wave field synthesis is a reproduction technique using a large number of densely placed loudspeakers (loudspeaker array). The underlying theory, however, assumes a continuous distribution of loudspeakers. Individual loudspeakers placed at discrete positions constitute a spatial sampling process t...
متن کاملOn the Use of Irregularly Spaced Loudspeaker Arrays for Wave Field Synthesis, Potential Impact on Spatial Aliasing Frequency
Wave Field Synthesis (WFS) is a physical based sound reproduction technique. It relies on linear arrays of regularly spaced omnidirectional loudspeakers. A fundamental limitation of WFS is that the synthesis remains correct only up to a corner frequency referred to as spatial aliasing frequency. This paper addresses irregular spacing of loudspeaker array for WFS. Adapted driving functions are d...

متن کاملOn the Secondary Source Type Mismatch in Wave Field Synthesis Employing Circular Distributions of Loudspeakers
The theory of wave field synthesis has been formulated for linear and planar arrays of loudspeakers but has been found to be also applicable with arbitrary convex loudspeaker contours with acceptable error. The main source of error results from the fact that the required properties of the employed loudspeakers are dictated by the Neumann Green’s function of the array geometry under consideratio...
