摘要： Multiple virtual source locations may be defined for a volume within which audio objects can move. A set-up process for rendering audio data may involve receiving reproduction speaker location data and pre-computing gain values for each of the virtual sources according to the reproduction speaker location data and each virtual source location. The gain values may be stored and used during "run time," during which audio reproduction data are rendered for the speakers of the reproduction environment. During run time, for each audio object, contributions from virtual source locations within an area or volume defined by the audio object position data and the audio object size data may be computed. A set of gain values for each output channel of the reproduction environment may be computed based, at least in part, on the computed contributions. Each output channel may correspond to at least one reproduction speaker of the reproduction environment.

摘要： The present document relates to a method and an apparatus for rendering input audio including at least one audio object and associated metadata, wherein the metadata includes audio object size metadata and audio object position metadata corresponding to the at least one audio object. The method comprises: receiving the audio object size metadata and the audio object position metadata; determining the at least a virtual audio object based on the input audio, the audio object size metadata and the audio object position metadata; determining a location of the at least a virtual audio object based on at least one of the audio object size metadata and the audio object position metadata; determining a gain of the virtual audio object; and rendering the audio object to one or more speaker feeds based on the location of the at least a virtual audio object and the gain of the virtual audio object.
