摘要： Method for processing audio objects by an audio client apparatus is described wherein the method comprises:receiving or determining spatial listener information, the spatial listener information defining including one or more listener positions, orientations and/or foci of one or more listeners in the audio space; the audio client apparatus selecting one or more audio object identifiers from a set of audio object identifiers defined in a manifest file stored in a memory of the audio client apparatus, an audio object identifier defining an audio object being associated with audio object position information for defining one or more positions of the audio object in the audio space; the selecting of the one or more audio object identifiers by said audio client apparatus being based on the spatial listener information and the audio object position information of audio object identifiers in said manifest file; and, the audio client apparatus using said one or more selected audio object identifiers to request transmission of audio data and audio object metadata associated with the one or more audio objects defined by the selected audio object identifiers to said audio client apparatus.
