Abstract: System-wide clock synchronization and latency reduction of audio signals in a wireless multi-channel audio system (WMAS). The apparatus includes: a base station and a wireless audio device. The base station includes: a master clock source; a framer operative to generate base station frames containing audio data and related audio clock timing derived from said master clock source; and a transmitter operative to transmit the frames over the WMAS. The wireless audio device includes: a receiver operative to receive frames from the base station over the WMAS; and a clock generator circuit operative to input a local clock signal generated by a frame synchronization circuit to generate therefrom multiple clocks derived from the timing signal to synchronize the wireless audio device to base station frames and to enable thereby communications according to a previously determined schedule with the base station.

Abstract: An electronic device may exchange packets with a second electronic device. These packets may include transmit times, based on a given clock in a given electronic device when the packets were transmitted. Moreover, when the packets are received by the electronic device, the electronic device may store associated receive times based on a clock in the electronic device. Using minimum time differences between the transmit and receive times, the electronic device may calculate a time offset between the electronic device and the second electronic device, which may then be used to determine future times in a clock domain of the second electronic device. Moreover, the electronic device may provide additional packets to the second electronic device, where a given additional packet includes audio data, and a playback time, corresponding to a given future time, when the audio data is to be played back by the second electronic device.

An optional endoskeleton is provided to support internal components. The system preferably provides a digital electronic controller, and the electrical interface is a digital data and power bus, with multiplexed communications between the elements of the system. The elements of the system preferably include at least one speaker, and other audiovisual and communications components. Multiple modules may be interconnected, communicating through the electrical interface. A base module may be provided to provide power and typical control, user and audiovisual interface connectors.

Abstract: Example techniques involve noise-robust acoustic echo cancellation. An example implementation may involve causing one or more speakers of the playback device to play back audio content and while the audio content is playing back, capturing, via the one or more microphones, audio within an acoustic environment that includes the audio playback. The example implementation may involve determining measured and reference signals in the STFT domain. During each nth iteration of an acoustic echo canceller (AEC): the implementation may involve determining a frame of an output signal by generating a frame of a model signal by passing a frame of the reference signal through an instance of an adaptive filter and then redacting the nth frame of the model signal from an nth frame of the measured signal. The implementation may further involve determining an instance of the adaptive filter for a next iteration of the AEC.

Abstract: Examples described herein involve configuring a playback device based on distortion, such as that caused by a barrier. One implementation may involve causing the playback device to play audio content according to an existing playback configuration, determining an existing frequency response of the playback device in a given system, and determining whether a difference between the existing frequency response of the playback device in the given system and a predetermined frequency response for the playback device is greater than a predetermined distortion threshold. If it is determined that the difference between the existing frequency response of the playback device and the predetermined frequency response for the playback device is greater than the predetermined distortion threshold, then the existing playback configuration of the playback device is changed to an updated playback configuration of the playback device and the playback device plays audio content according to the updated playback configuration.

Abstract: A head mounted display (HMD) worn on a head of a first person provides an electronic call between the first person and a second person. The HMD includes or more sensors that determine one of a size or a shape of a physical environment where the first person is located. A display displays a virtual image of the second person during the electronic call, and one or more processors adjust a voice of the second person played to the first person to compensation for sound reverberation. The HMD include speakers that play the voice of the second person in binaural sound compensated for the sound reverberation.

Abstract: Embodiments include an audio system comprising an audio device, a speaker, and a processor. The audio system is configured to receive data from one or more sensors corresponding to persons in a room and/or characteristics of a room, and responsively take action to modify one or more characteristics of the audio system, share the information with other systems or devices, and track data over time to determine patterns and trends in the data.

Abstract: Example techniques may involve a playback device modifying its playback configuration when the playback device is placed onto a device base. In an example implementation, the playback device may receive, via an 802.15-compatible radio of one or more network interfaces, one or more packets comprising data representing an identifier of the first device base. After receipt of the one or more packets, the playback device queries a database for state information corresponding to the identifier of the first device base and modifies a playback configuration of the playback device from a first configuration to a second configuration based on the queried state information corresponding to the identifier of the first device base.

Abstract: A playback device is configured to: based on a room setting of the playback device, determine that the playback device is associated with a first room of a media playback system; operate in a first mode that is associated with a first user type and a first set of playback control options; determine that the room setting of the playback device has changed; determine that the playback device is no longer associated with the first room and is associated with a second room of the media playback system; transition to operating in a second mode; determine that the playback device is no longer associated with the second room and is associated with the first room; transition to operating in the first mode; receive a playback command; determine that the playback command corresponds to a playback control option within the first set; and execute the playback command.

Abstract: An example playback device is a first playback device in a media system. The first playback device is configured to resolve audio conflicts with one or more other playback devices in the media system by: (i) capturing, via a microphone of the first playback device, audio content played back by a second playback device, (ii) identifying the second playback device as a source of the captured audio content; and (iii) responsive to identifying the second playback device as the source of the captured audio content, altering a playback characteristic of the second playback device or the first playback device to reduce an audio interference between the first and second playback devices.
