Abstract
A first audio apparatus generates a data signal comprising data for an audio scene, the data comprising input audio source data for at least a first audio source and acoustic object data for at least one acoustic object in the audio scene, the acoustic object data comprising acoustic coupling data and spatial property data for the acoustic object. A second audio apparatus comprises a receiver (201) for receiving the signal. A generator (205) generates object audio source data for an object audio source representing audio emitted in the audio scene by the acoustic object from coupling of audio from the first audio source. The generator (205) is arranged to generate the object audio source data in response to the acoustic coupling data, the spatial property data, and the input audio source data. A renderer (203) renders the audio scene, the rendering including rendering the object audio source data.
