    摘要： 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.

    摘要： Embodiments are directed to speakers and circuits that reflect sound off a ceiling to a listening location at a distance from a speaker. The reflected sound provides height cues to reproduce audio objects that have overhead audio components. The speaker comprises upward firing drivers to reflect sound off of the upper surface and represents a virtual height speaker. A virtual height filter based on a directional hearing model is applied to the upward-firing driver signal to improve the perception of height for audio signals transmitted by the virtual height speaker to provide optimum reproduction of the overhead reflected sound. The virtual height filter may be incorporated as part of a crossover circuit that separates the full band and sends high frequency sound to the upward-firing driver.

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.

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.

    摘要翻译： 对于处理包括多个独立单声道音频流的音频数据的自适应音频系统描述实施例。 一个或多个流与其相关联的元数据，其指定流是基于信道还是基于对象的流。 基于频道的流具有通过频道名称编码的渲染信息; 并且基于对象的流具有通过在相关联的元数据中编码的位置表达式编码的位置信息。 编解码器将独立音频流打包成包含所有音频数据的单个串行比特流。 该配置允许根据异轴参考系渲染声音，其中声音的渲染位置基于播放环境的特性（例如，房间大小，形状等），以对应于混音器的 意图。 对象位置元数据包含使用设置为播放自适应音频内容的房间中的可用扬声器位置来正确播放声音所需的适当的同心异动帧参考信息。
