Abstract: Embodiments are described for a method and system of rendering and playing back spatial audio content using a channel-based format. Spatial audio content that is played back through legacy channel-based equipment is transformed into the appropriate channel-based format resulting in the loss of certain positional information within the audio objects and positional metadata comprising the spatial audio content. To retain this information for use in spatial audio equipment even after the audio content is rendered as channel-based audio, certain metadata generated by the spatial audio processor is incorporated into the channel-based data. The channel-based audio can then be sent to a channel-based audio decoder or a spatial audio decoder. The spatial audio decoder processes the metadata to recover at least some positional information that was lost during the down-mix operation by upmixing the channel-based audio content back to the spatial audio content for optimal playback in a spatial audio environment.

Abstract translation: 描述了使用基于频道的格式来渲染和回放空间音频内容的方法和系统的实施例。 通过基于传统的基于信道的设备回放的空间音频内容被转换成适当的基于频道的格式，导致音频对象内的某些位置信息的丢失和包括空间音频内容的位置元数据。 即使在将音频内容呈现为基于频道的音频之后，为了保留用于空间音频设备的该信息，由空间音频处理器生成的某些元数据被并入到基于频道的数据中。 然后可以将基于频道的音频发送到基于频道的音频解码器或空间音频解码器。 空间音频解码器处理元数据以恢复低混音操作期间丢失的至少一些位置信息，通过将基于频道的音频内容上回到空间音频内容以在空间音频环境中进行最佳重放。

Abstract: Embodiments are described for rendering spatial audio content through a system that is configured to reflect audio off of one or more surfaces of a listening environment. The system includes an array of audio drivers distributed around a room, wherein at least one driver of the array of drivers is configured to project sound waves toward one or more surfaces of the listening environment for reflection to a listening area within the listening environment and a renderer configured to receive and process audio streams and one or more metadata sets that are associated with each of the audio streams and that specify a playback location in the listening environment.

Abstract: Embodiments are described for a system of rendering object-based audio content through a system that includes individually addressable drivers, including at least one driver that is configured to project sound waves toward one or more surfaces within a listening environment for reflection to a listening area within the listening environment; a renderer configured to receive and process audio streams and one or more metadata sets associated with each of the audio streams and specifying a playback location of a respective audio stream; and a playback system coupled to the renderer and configured to render the audio streams to a plurality of audio feeds corresponding to the array of audio drivers in accordance with the one or more metadata sets.
