Abstract

A particle generator for generating a speaker signal for a speaker channel in a multi-channel reproduction environment includes a position generator for providing a plurality of positions where the audio source is to occur, as well as a time generator for providing times of occurrence when the audio source is to occur, a time being associated with a position. Also, an individual pulse response generator for generating individual pulse response information for each position of the plurality of positions is provided. A combination pulse response is formed by a pulse response combiner for combining the individual pulse response information in accordance with the times of occurrence. This overall pulse response is finally used to adjust a filter with which the audio signal is finally filtered.
