Abstract: Embodiments create an audio decoder which receives a plurality of packets of different packet types, having one or more scene configuration packets providing renderer configuration information defining a usage of scene objects and/or of scene characteristics, having one or more scene update packets defining a update of scene metadata for the rendering, and having one or more scene payload packets having definitions of one or more of the scene objects and/or of one or more of the scene characteristics; selects definitions of one or more scene objects and/or of one or more scene characteristics, included in the scene payload packets, for rendering in dependence on the renderer configuration information; and updates one or more scene metadata in dependence on a content of the one or more scene update packets. Further embodiments create encoders, methods and bitstreams.

Abstract: Embodiments create an audio decoder which spatially renders one or more audio signals. The audio decoder receives a plurality of packets of different packet types, comprising one or more scene configuration packets providing a renderer configuration information defining a usage of scene objects and/or a usage of scene characteristics, and comprising one or more scene update packets defining a update of scene metadata for the rendering, and comprising one or more scene payload packets comprising definitions of one or more of the scene objects and/or definitions of one or more of the scene characteristics. The audio decoder selects definitions of one or more scene objects and/or definitions of one or more scene characteristics, which are in included in the scene payload packets, for the rendering in dependence on the renderer configuration information. The audio decoder updates one or more scene metadata in dependence on a content of the one or more scene update packets.

Abstract: An apparatus for rendering a virtual audio scene according to an embodiment is provided. One or more sound sources are emitting sound in the virtual audio scene. The apparatus has an input interface configured for receiving audio information, wherein the audio information has audio information for the virtual audio scene. Moreover, the apparatus has a renderer configured for generating, depending on the audio information for the virtual audio scene, one or more audio output channels for reproducing the virtual audio scene. If information on a current acoustic environment of the virtual audio scene is not available for the renderer, the renderer is configured to generate the one or more audio output channels for reproducing the virtual audio scene depending on information on a default acoustic environment.

Abstract: An apparatus according to an embodiment. The apparatus comprises a receiving interface for receiving a plurality of spatial object representations of a plurality of spatial objects, wherein each of the plurality of spatial object representations is represented in at least one of two or more spatial representation domains. Moreover, the apparatus comprises a converter for converting one or more of the plurality of spatial object representations from a first one of the two or more spatial representation domains into a second one of the two or more spatial representation domains.
