摘要： A display device including at least one speaker; a moveable display configured to be moved from a first position to a second position, wherein the display has a first spatial physical relationship with the at least one speaker at the first position and has a second spatial physical relationship with the at least one speaker at the second position; and a processor configured to control the at least one speaker and the display. In addition, the processor is configured to output audio from the at least one speaker, when the display is in the first position, and when receiving an information signal indicating the display has been moved to the second position from the first position, change the output of the audio from the at least one speaker based on the second spatial physical relationship.

摘要： Turntable control systems are disclosed. A playback device can include an analog audio source component such as a turntable. The playback device is configured to cause playback of first audio based on analog audio signals generated by the analog audio source component. Based on an indication that analog audio signals are no longer being generated, the playback device requests, via a network interface, audio content from one or more remote computing devices. The request can include identifying related content based on the first audio. The playback device receives, via the network interface, second audio content from, and causes playback of second audio based on the second audio content.

摘要： A system that is capable of controlling multiple entertainment systems and/or speakers using voice commands. The system receives voice commands and may determine audio sources and speakers indicated by the voice commands. The system may generate audio data from the audio sources and may send the audio data to the speakers using multiple interfaces. For example, the system may send the audio data directly to the speakers using a network address, may send the audio data to the speakers via a voice-enabled device or may send the audio data to the speakers via a speaker controller. The system may generate output zones including multiple speakers and may associate input devices with speakers within the output zones. For example, the system may receive a voice command from an input device in an output zone and may reduce output audio generated by speakers in the output zone.

摘要： The present document relates to methods and apparatus for rendering input audio for playback in a playback environment. The input audio includes at least one audio object and associated metadata, and the associated metadata indicates at least a location of the audio object. A method for rendering input audio including divergence metadata for playback in a playback environment comprises creating two additional audio objects associated with the audio object such that respective locations of the two additional audio objects are evenly spaced from the location of the audio object, on opposite sides of the location of the audio object when seen from an intended listener's position in the playback environment, determining respective weight factors for application to the audio object and the two additional audio objects, and rendering the audio object and the two additional audio objects to one or more speaker feeds in accordance with the determined weight factors.

摘要： Content rules engines for playback devices are disclosed herein. A media playback system receives a first command to form a synchrony group comprising a plurality of playback devices. The system receives a second command for the synchrony group to play back first audio content. In response to the second command, the first audio content is played back via the synchrony group. The system receives (i) second audio content to be played back by one or more of the playback devices of the synchrony group and (ii) content source properties associated with an audio source of the second audio content. The system accesses a rules engine to determine playback restrictions based at least in part on the content source properties. Based at least in part on the playback restrictions, operation of one or more of the playback devices is restricted.
