Encoding and rendering of object based audio indicative of game audio content

摘要

In some embodiments, a method (typically performed by a game console) for generating an object based audio program indicative of game audio content (audio content pertaining to play of or events in a game, and optionally also other information regarding the game), and including at least one audio object channel and at least one speaker channel. In other embodiments, a game console configured to generate such an object based audio program. Some embodiments implement object clustering in which audio content of input objects is mixed to generate at least one clustered audio object, or audio content of at least one input object is mixed with speaker channel audio. In response to the program, a spatial rendering system (e.g., external to the game console) may operate with knowledge of playback speaker configuration to generate speaker feeds indicative of a spatial mix of the program's speaker and object channel content.

1. A method for generating an object based audio program indicative of game audio content, said method including steps of:
(a) determining at least one audio object channel, wherein each said audio object channel is indicative of at least one audio object, and at least one said audio object channel is indicative of game audio content; (b) determining at least one speaker channel, said at least one speaker channel being associated with a first speaker configuration, wherein at least one said speaker channel is indicative of additional game audio content; and (c) generating the object based audio program, including by encoding data indicative of each said audio object channel and each said speaker channel, wherein step (a) includes steps of: (d) identifying a set of input audio objects which are indicative of game audio content, where the set consists of N audio objects and N is a positive integer; and (e) replacing the set of input audio objects with a reduced set of audio objects, where the reduced set consists of M audio objects, M is a positive integer less than N and said at least one audio object channel is indicative of the reduced set of audio objects, and wherein step (c) includes the step of: generating the object based audio program such that said object based audio program is indicative of the reduced set of audio objects, and includes M object channels and at least one speaker channel associated with a second speaker configuration, the second speaker configuration being different from the first speaker configuration.
