Abstract
An audio encoding apparatus comprises an audio receiver () receiving audio items representing an audio scene and a metadata receiver () receives input presentation metadata for the audio items describing presentation constraints for the rendering of the audio items. The presentation constraints constrain a rendering parameter that can be adapted when rendering the audio items. An audio encoder () generates encoded audio data for the audio scene by encoding the plurality of audio items with the encoding being adapted in response to the input presentation metadata. A metadata circuit () generates output presentation metadata from the input presentation metadata. The output presentation metadata comprises data for encoded audio items which constrain the extent by which an adaptable parameter of a rendering can be adapted when rendering the encoded audio items. An output () generates an encoded audio data stream comprising the encoded audio data and the output presentation metadata.
