Abstract

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.
