Abstract

An apparatus for changing an audio scene has a direction determiner and an audio scene processing apparatus. The audio scene has at least one audio object having an audio signal and associated meta data. The direction determiner determines a direction of a position of the audio object with respect to a reference point based on the meta data of the audio object. Further, the audio scene processing device processes the audio signal, a processed audio signal derived from the audio signal or the meta data of the audio object based on a determined directional function and the determined direction of the position of the audio object.
