Investigation of Spatial Aliasing Artifacts of Wave Field Synthesis in the Temporal Domain
نویسنده
چکیده
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 contribution analyzes the aliasing artifacts for broadband signals. The derived results give insights into the spatio-temporal structure of spatial aliasing for e. g. transient signals.

Attenuation of spatial aliasing in CMP domain by non-linear interpolation of seismic data along local slopes
Spatial aliasing is an unwanted side effect that produces artifacts during seismic data processing, imaging and interpolation. It is often caused by insufficient spatial sampling of seismic data and often happens in CMP (Common Mid-Point) gather. To tackle this artifact, several techniques have been developed in time-space domain as well as frequency domain such as frequency-wavenumber, frequen...

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 ...

Wave field synthesis (WFS) and higher-order Ambisonics (HOA) are two sound reproduction techniques that facilitate a high number of reproduction channels to overcome the sweet-spot limitation known from conventional stereophonic reproduction techniques. HOA is based on a representation of the reproduced wave field in terms of spatial harmonics, WFS is based on the KirchhoffHelmholtz integral. I...
