Patent ID: 8363847

Claim:
A device for aliasing correction in a wave field synthesis system with a wave field synthesis module and an array of loudspeakers for sound supply of a show area, wherein the wave field synthesis module is configured to receive an audio signal associated with a virtual sound source and source position information associated with the virtual sound source, and to calculate, taking into account loudspeaker position information, component signals for the loudspeakers due to the virtual sound source, comprising: an ascertainer for ascertaining an aliasing filter property specific for a virtual sound source using the source position information, wherein the ascertainer for ascertaining is configured to acquire, for the loudspeakers in the array, wave field synthesis scaling values and wave field synthesis delay values associated with the loudspeakers, and to ascertain the aliasing filter property based on a listening point in the show area and the wave field synthesis scaling values and wave field synthesis delay values,; and an adaptive anti-aliasing filter for adaptive filtering of the audio signal associated with the virtual sound source or the component signals associated with the virtual sound source, wherein the adaptive anti-aliasing filter is adjusted according to the aliasing filter property specific for the virtual sound source to effect an aliasing correction.
