Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 15:
16. A method comprising:
decoding, based on a coded audio bitstream, a representation of a soundfield having six degrees of freedom (6DoF), wherein the coded audio bitstream comprises an MPEG-I bitstream;
decoding, based on 6DoF metadata of the coded audio bitstream, a first syntax element indicating a selection of either a head-related transfer function (HRTF) or a binaural room impulse response (BRIR);
decoding, based on the 6DoF metadata of the coded audio bitstream, a second syntax element indicating whether reverb is enabled or disabled;
responsive to the second syntax element indicating that reverb is enabled:
decoding, based on the coded audio bitstream, a plurality of room reverb coefficient sets for a room, each of the room reverb coefficient sets corresponding to a different candidate position in the room; and
selecting, based on data generated by one or more sensors of an XR headset, a particular room reverb coefficient set from the plurality of room reverb coefficient sets that corresponds to a position of the XR headset and

rendering, by a 6DoF audio renderer and using the selected HRTF or BRIR and selectively using reverb based on the first syntax element and using the particular room reverb coefficient set, speaker feeds from the soundfield, wherein the XR headset includes a plurality of speakers driven via the rendered speaker feeds.
