    Abstract: 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.

    Abstract translation: 可以为音频对象可以移动的音量定义多个虚拟源位置。 用于呈现音频数据的设置过程可以包括根据再现扬声器位置数据和每个虚拟源位置来接收再现扬声器位置数据和针对每个虚拟源的预计算增益值。 可以在“运行时间”期间存储和使用增益值,在此期间为再现环境的扬声器呈现音频再现数据。 在运行时间期间,对于每个音频对象,可以计算由音频对象位置数据和音频对象大小数据定义的区域或卷内的虚拟源位置的贡献。 可以至少部分地基于所计算的贡献来计算再现环境的每个输出通道的一组增益值。 每个输出通道可以对应于再现环境的至少一个再现扬声器。

    Abstract: Embodiments are described for an adaptive audio system that processes audio data comprising a number of independent monophonic audio streams. One or more of the streams has associated with it metadata that specifies whether the stream is a channel-based or object-based stream. Channel-based streams have rendering information encoded by means of channel name; and the object-based streams have location information encoded through location expressions encoded in the associated metadata. A codec packages the independent audio streams into a single serial bitstream that contains all of the audio data. This configuration allows for the sound to be rendered according to an allocentric frame of reference, in which the rendering location of a sound is based on the characteristics of the playback environment (e.g., room size, shape, etc.) to correspond to the mixer's intent. The object position metadata contains the appropriate allocentric frame of reference information required to play the sound correctly using the available speaker positions in a room that is set up to play the adaptive audio content.
