| description | An (encoding) apparatus comprises a metadata generator (203) generating metadata for audio data for a plurality of audio elements representing audio sources in an environment. The metadata comprises acoustic environment data for the environment where the acoustic environment data describes properties affecting sound propagation for the audio sources in the environment. At least some of the acoustic environment data is applicable to a plurality of listening poses in the environment and the properties include both static and dynamic properties. A bitstream generator (205) generates the bitstream to include the metadata and often also audio data representing the audio elements for the audio sources in the environment. A decoding apparatus may comprise a receiver for receiving the bitstream and a renderer for rendering audio for the audio environment based on the acoustic environment data and on audio data for the audio elements. |
