Abstract (en)
An audio apparatus comprises a receiver (201) receiving an audio signal and a geometric model for an audio source object. The geometric model may be a polygon mesh. A position circuit (203) determines a set of point audio source positions for the audio source object based on the geometric model such that the point audio source positions are spatially distributed within the audio source object. A point audio signal generator (205) generates a point audio source signal for the point audio source positions from the audio signal. In some cases, the point audio signal may be a copy of the received audio signal. A data generator (207) generates a data representation of the audio source object comprising the set of point audio source positions and the at least one point audio source signal. A renderer (301) may render the audio source object by rendering point audio source signals from the point audio source positions.
