Abstract: Methods and audio processing units for generating an object based audio program including conditional rendering metadata corresponding to at least one object channel of the program, where the conditional rendering metadata is indicative of at least one rendering constraint, based on playback speaker array configuration, which applies to each corresponding object channel, and methods for rendering audio content determined by such a program, including by rendering content of at least one audio channel of the program in a manner compliant with each applicable rendering constraint in response to at least some of the conditional rendering metadata. Rendering of a selected mix of content of the program may provide an immersive experience.

Abstract: Novel methods and systems for creating and using user profiles for dialog boost and sound equalizer adjustment to compensate for various ambient sound situations. For creating profiles when not at the ambient sound, a synthesized/pre-recorded ambient noise can be mixed with the media to simulate the noise conditions.

Abstract: A media fingerprint archive system generates and archives media fingerprints from second media content portions such as commercials. A downstream media measurement system can extract/derive query fingerprints from an incoming signal and query the media fingerprint archive system whether any of the query fingerprints matches any archived fingerprints. If so, the media measurement system can perform media measurements on a specific secondary media content portion from which the matched query fingerprint is derived. If not, the media measurement system can analyze media characteristics of a media content portion to determine whether the media content portion is a secondary media content portion and perform media measurement if needed to. The media measurement system may send fingerprints from an identified secondary media content portion to the media fingerprint archive system for storage.

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.

Abstract translation: 媒体指纹存档系统从诸如商业广告的第二媒体内容部分生成和归档媒体指纹。 下游媒体测量系统可以从输入信号中提取/导出查询指纹，并查询媒体指纹存档系统是否任何查询指纹与任何归档指纹匹配。 如果是这样，媒体测量系统可以对从其导出匹配的查询指纹的特定辅助媒体内容部分执行媒体测量。 如果不是，媒体测量系统可以分析媒体内容部分的媒体特性，以确定媒体内容部分是否是次要媒体内容部分，并且如果需要，则执行媒体测量。 媒体测量系统可以将指纹从识别的次要媒体内容部分发送到媒体指纹存档系统以进行存储。

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.
