Apparatus And Method For Rendering Multi Path Sound Diffraction With Multi Layer Raster Maps

Abstract: An apparatus (100) for decoding according to an embodiment is provided. The apparatus (100) comprises an audio signal decoder (110) for decoding an encoding of an audio object signal of an audio object. Moreover, the apparatus (100) comprises a metadata decoder (120) for decoding an encoding of metadata, wherein, for each of a plurality of listener positions, the metadata comprises information on two or more different sound wave propagation paths from a sound source position of the audio object to the listener position. Furthermore, the apparatus (100) comprises a signal generator (130) for generating one or more audio output signals depending on the audio object signal and depending on the information on the two or more different sound wave propagation paths from the sound source position to a current listener position of the plurality of listener positions.
