Abstract: A system for playing media content items operates to provide smooth transitions between the media content items to continuously support a user's repetitive motion activity. The system can generate crossfade data containing information for transitions between media content items. The mix-in and mix-out points for the transitions are calculated to eliminate one or more portions of media content items that have lower musical energy than a majority portion of the items, and to maintain substantially consistent and/or stable musical energy (e.g., audio power or sound power) throughout the media content items including transitions therebetween.

An example implementation involves a first playback device detecting, via at least one proximity sensor, motion in proximity to the proximity sensor. In response, the first playback device sends, to a second playback device, one or more first messages indicating that the first playback device detected motion. Afterwards, the first playback device receives, via the network interface from the second playback device in response to the one or more first messages, one or more second messages that instruct the first playback device to pre-cache, from a network source, a portion of audio content indicated in a playback queue associated with a playback device group including the first playback device and the second playback device. The first playback device receives a command to play back the playback queue and plays back the audio content indicated in the playback queue jointly with the second playback device.

Abstract: An audio processing system includes a server complex in communication with a network. The server complex receives a digital audio file and one or more analog domain control settings from a client device across the network. A digital-to-analog converter converts the digital audio file to an analog signal. One or more analog signal processors apply at least one analog modification to the analog signal in accordance with the one or more analog domain control settings. An analog-to-digital converter converts the modified analog signal to a modified digital audio file. The server complex can then deliver the modified digital audio file to the client device across the network.

Abstract: Described are techniques for configuring a group of audio devices to distribute audio data based on the communications undertaken by the audio devices. Audio devices that are not currently exchanging data via a communication link with an external device may be prioritized for use as a master device over other audio devices that may consume airtime or other resources performing such communications. Audio devices that lack communication links with external devices may be prioritized for use as a master device over other audio devices that maintain such communication links. If the communication links associated with a current master device or other audio devices change, a different master device may be automatically selected.
