Abstract

A more clear-cut separation of a first audio signal within a first region of a sonication area of a plurality of loudspeakers is achieved in that a calculator calculates that version of the audio signals which results from the spatially selective reproduction of the audio signals at this first region, in that a masking threshold is calculated as a function of the version of that audio signal which is to be separated from the one or more other audio signals at this region, and in that the emission of the audio signals for spatially selective reproduction to the outputs of the plurality of loudspeakers is influenced as a function of a comparison of the masking threshold with the version of the one or more other, i.e. spurious, audio signals.
