Patent ID: 8090126

Claim:
An apparatus for generating a speaker signal for a speaker channel associated with a speaker which may be mounted, in a reproduction environment, at a speaker position of a plurality of speaker positions, the apparatus comprising: a source for providing an audio signal for an audio source which is to occur at different positions and at different times within an audio scene; a position generator for providing a plurality of positions where the audio source is to occur; a time generator for providing times of occurrence when the audio source is to occur, a time being associated with a position; an individual pulse response generator for generating individual pulse response information for each position of the plurality of positions for a speaker channel on the basis of the positions and information on the speaker channel; a pulse response combiner for combining the individual pulse response information in accordance with the times of occurrence to acquire combination pulse response information for the speaker channel; and a filter for filtering the audio signal using the combination pulse response information to acquire a speaker signal for the speaker channel, which signal represents the audio source which occurs at different positions and at different times within the audio scene.
