Spatial Audio Rendering with Listener Motion Compensation using Metadata

An article of manufacture comprising:

• a non-transitory machine-readable storage medium having stored therein metadata of a sound program, wherein the sound program has an audio scene component, ASC, the metadata comprising:
• a first data structure that instructs a spatial audio renderer on whether to render the ASC as a virtual sound source without compensating for motion of a listener of a playback, when rendering the sound program for the playback;
• and
• a second data structure that instructs the spatial audio renderer, when the listener of the playback is not motionless and the first data structure indicates that the ASC may be rendered with compensation for the motion of the listener, as to a reference to use when compensating for the motion of the listener.

An encoding side method for spatial audio rendering using metadata, the method comprising:

• encoding an audio scene component, ASC, of a sound program into a bitstream;
• and
• providing metadata of the sound program, wherein the metadata comprises:
• a first data structure that instructs a spatial audio renderer on whether to render the ASC as a virtual sound source while considering propagation delay, Doppler, or both, when the spatial audio renderer is rendering the sound program for playback and the virtual sound source is moving relative to a reference position such as a position of a listener of the playback.
