Abstract

An apparatus for generating at least one audio output signal based on an audio data stream having audio data relating to one or more sound sources is provided. The apparatus has a receiver for receiving the audio data stream having the audio data. The audio data has one or more pressure values for each one of the sound sources. Furthermore, the audio data has one or more position values indicating a position of one of the sound sources for each one of the sound sources. Moreover, the apparatus has a synthesis module for generating the at least one audio output signal based on at least one of the one or more pressure values of the audio data of the audio data stream and based on at least one of the one or more position values of the audio data of the audio data stream.
