    Abstract: Techniques are disclosed for transmitting an announcement to one or more devices. In one example, a first device receives a first message that includes an announcement, the announcement associated with a voice that spoke the announcement. The first device may determine the announcement from the first message, and then identify one or more devices for receiving the announcement. The one or more devices may have a particular device type of a plurality of different device types comprising at least a mobile device. The first device may determine a network path through which a second message is transmitted based at least in part on the location of a second device. In accordance with a determination that the second device is located within a local area network associated with a home environment, the first device transmits the second message over the local area network. In accordance with a determination that the second device is located away from a local area network associated with a home environment, the first device transmits the second message over the wide area network.

    Abstract: A system and method is described for determining whether a loudspeaker device has relocated, tilted, rotated, or changed environment such that one or more parameters for driving the loudspeaker may be modified and/or a complete reconfiguration of the loudspeaker system may be performed. In one embodiment, the system may include a set of sensors. The sensors provide readings that are analyzed to determine 1) whether the loudspeaker has moved since a previous analysis and/or 2) a distance of movement and/or a degree change in orientation of the loudspeaker since the previous analysis. Upon determining the level of movement is below a threshold value, the system adjusts previous parameters used to drive one or more of the loudspeakers. By adjusting previous parameters instead of performing a complete recalibration, the system provides a more efficient technique for ensuring that the loudspeakers continue to produce accurate sound for the listener.

    Abstract: An audio system having a variable reset volume, and a method of conditionally resetting a volume parameter, are described. The audio system can include a processor to generate an audio signal for a speaker to convert into a sound. A volume parameter of the audio signal can be set before a user pauses playback of the audio signal. The processor can determine that the volume parameter is outside of a resting volume range, and that the user resumes playback of the audio signal at least a selected interval after pausing playback. The processor can responsively reset the volume parameter when playback is resumed to a different level based on one or more acoustic factors, such as an audio decay time of a surrounding environment. The different level can be within the resting volume range. Other aspects are also described and claimed.

    Abstract: Various techniques relating to the buffering of a live audio broadcast on an electronic device and the subsequently playback the buffered data are provided. In one embodiment, the playback speed of the buffered data may be increased relative to the actual speed at which the data was originally broadcasted. If the buffered playback (using the increased playback speed) synchronizes or catches up to the live broadcast, the electronic device may disable buffering and output the live stream instead. This decreases processing demands by lowering processing cycles required for buffering (encoding, etc.) and playback of the buffered data (decoding, etc.), thereby reducing power consumption.

    Abstract: In one aspect a device-side audio handling input/output unit (DIO) of a hardware device writes audio data generated by the hardware device within a ring buffer. An input provided by a user for activation of a software program is received, and a notification that the software program is ready to accept the audio data is generated. A system-side audio handling input/output unit (SIO) additionally provides past audio data from the ring buffer to the software program. Other aspects also are described.
