Spatial Aliasing Artifacts Produced by Linear and Circular Loudspeaker Arrays used for Wave Field Synthesis

چکیده
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 to aliasing artifacts. This paper derives the spatial aliasing artifacts and anti-aliasing conditions for linear and circular loudspeaker arrays used for wave field synthesis based reproduction. Revision: March 9, 2006

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 کاملTimbral Coloration in High Resolution Sound Field Reproduction Due to Spatial Bandwidth Limitation
Sound field reproduction methods based on orthogonal expansions like e.g. higher order Ambisonics always introduce a limitation of the spatial bandwidth of the loudspeaker driving signals. As a consequence, the desired component of the reproduced wave field is similarly bandlimited. This leads to a pronounced sweet spot around the center of the loudspeaker distribution. This area is sweet both ...
متن کاملInvestigation of Spatial Aliasing Artifacts of Wave Field Synthesis in the Temporal Domain
Wave field synthesis (WFS) is a spatial sound reproduction technique that uses a high number of densely placed loudspeakers (secondary sources). This implies a spatial sampling process that may lead to aliasing artifacts. In the past, the spatial aliasing artifacts of WFS have mainly been investigated for the reproduction of monochromatic signals, and hence in the frequency domain. This contrib...
