20090220111	DEVICE AND METHOD FOR SIMULATION OF WFS SYSTEMS AND COMPENSATION OF SOUND-INFLUENCING PROPERTIES - An aliasing correction in a wave field synthesis system is achieved by ascertaining the aliasing filter property specific for a virtual source. This aliasing filter property, which, for example, may be the aliasing frequency is ascertained by help of the source position information. This aliasing filter property is used for an adaptive anti-aliasing filter for adaptive filtering of the audio signal associated with the source or the component signals associated with the source.	09-03-2009

20080219484	Apparatus and Method for Controlling a Plurality of Speakers Means of a Dsp - In a reproduction environment, speakers are grouped in directional groups, wherein the directional groups overlap with respect to the associated speakers so that speakers are present which have a speaker parameter having different values for the first directional group and the second directional group. A controller for controlling a plurality of speakers has a provider for providing a source position of an audio source, wherein the source position is located between the first directional group position and the second directional group position. The apparatus further has a calculator for calculating a speaker signal for the at least one speaker, based on the first parameter value for the speaker parameter and based on the second parameter value for the speaker parameter.	09-11-2008
