Summary:An audio apparatus comprises a first receiver (501) receiving audio data for sources of a scene comprising acoustic environments divided by acoustically attenuating boundaries. A second receiver (501) receives metadata comprising transfer region data describing transfer regions with reduced acoustic attenuation in the acoustically attenuating boundaries and energy transfer parameters where each energy transfer parameter indicates an energy attenuation between a pair of transfer regions. The energy attenuation indicates a proportion of audio energy at one transfer region propagating to another transfer region. A renderer (507) renders an audio signal for a first acoustic environment including a first audio component by rendering a first audio source of a second acoustic environment in dependence on an energy attenuation for a pair of transfer regions comprising a transfer region of an acoustically attenuating boundary of the first acoustic environment and another transfer region of an acoustically attenuating boundary of the second acoustic environment.
