Abstract: A method that includes displaying a user interface (UI) of a three-dimensional (3D) acoustic environment that includes a sound source; receiving a user selection, via an input device, of a location within the UI, the location towards which the sound source is to be oriented within the 3D acoustic environment; determining a set of parameters that define an orientation of the sound source towards the location within the 3D acoustic environment; determining that there is motion of the location or the sound source within the 3D acoustic environment; updating, without user intervention and based on the motion, the set of parameters to maintain the orientation of the sound source towards the location.

Abstract: The various aspects of the disclosure here enable a content creation side to control how discrete audio objects that make up a sound program are rendered by a decoding side to achieve greater realism, while enabling the decoder side to also control the rendering process to consider the positions and orientations of the objects as virtual sound sources relative to the listener. The same sound program can thus be optimally rendered by a variety of decoder side formats, such as binaural on headphone, cross-talked cancelled binaural on a stereo pair of speakers embedded in a device, or multichannel on an immersive loudspeaker layout, e.g., planar such as 5.1 and 7.1 surround sound layouts, 3D such as 7.1.4 or 22.2, etc. Other aspects are also described and claimed.

Abstract: The various aspects of the disclosure here enable a content creation side to control how discrete audio objects that make up a sound program are rendered by a decoding side to achieve high spatial resolution, while giving the content creator the flexibility to decide how complex the spatial audio rendering should be in the decoding side. Metadata associated with the sound program will instruct a spatial audio renderer on how complex its listener motion compensation should be. Other aspects are also described and claimed.

Abstract: The various aspects of the disclosure here enable a content creation side to control how a sound program is spatial audio rendered by a decoding side, so that an audio scene component in a metadata-specified three dimensional acoustic masking zone is not heard while another audio scene component in an un-masked zone of the sound program is heard by a listener of the playback. Other aspects are also described and claimed.
