A control device is configured to (i) define configuration data corresponding to a zone scene of a media playback system, the configuration data including an identification of at least a first zone player and a second zone player, (ii) cause a remote computing device to (a) receive the configuration data via a wide area network and (b) store the configuration data, (iii) while the first zone player and a third zone player are playing back first audio content in synchrony, display a selectable indication that, when selected, causes the zone scene to be invoked, and (iv) in response to receiving an input indicative of a selection of the selectable indication, cause the remote computing device to invoke the zone scene at the media playback system such that the first zone player and the second zone player play back second audio content in synchrony without the third zone player.

Multiple aspects of systems and methods for voice control and related features and functionality for various embodiments of media playback devices, networked microphone devices, microphone-equipped media playback devices, and speaker-equipped networked microphone devices are disclosed and described herein, including but not limited to designating and managing default networked devices, audio response playback, room-corrected voice detection, content mixing, music service selection, metadata exchange between networked playback systems and networked microphone systems, handling loss of pairing between networked devices, actions based on user identification, and other voice control of networked devices.

To avoid damage from overheating, playback device operation can be modulated based on input from temperature sensors. An example method includes obtaining, via one or more temperature sensors carried by the playback device, temperature data. Based on the temperature data, a first temperature parameter is detected. In response to detecting the first temperature parameter, a gain of audio playback is decreased by a first amount. After decreasing the gain of audio playback by the first amount, a second temperature parameter is detected. In response to detecting the second temperature parameter, the gain of audio playback is decreased by a second amount different than the first amount.

Examples described herein involve expanding playback of a media item from a first playback device to a second playback device. In one example, while a first playback device is playing a media item as part of a first zone, the first playback device identifies that a second playback device has moved to a location that is within a given physical proximity of the first playback. The first playback device determines that playback is to be expanded to the second playback device, and transmits a command to cause the second playback device to (i) join the first zone and (ii) begin to play the media item in synchrony with the first playback device.

A multi-channel and multi-zone audio environment is provided. Various inventions are disclosed that allow playback devices on one or more networks to provide an effective multi-channel and a multi-zone audio environment using timing information. According to one example, timing information is used to coordinate playback devices connected over a low-latency network to provide audio along with a video display. In another example, timing information is used to coordinate playback devices connected over a mesh network to provide audio in one or more zones or zone groups.

A tracking and communication system for microphones (10), comprising a plurality of microphones (10) installed in one or more zones (14) of contiguous or separate environments. Each microphone (10) is equipped with a radio unit which is connected to the microphone (10). The tracking and communication system comprises also a network of radio transceivers (11), which are positioned in said one or more zones (14) and which are connected wirelessly or through one or more cable one to each other, being configured to receive signals from said microphones (10) and to transmit to them a plurality of data, and a command and control unit (12), to which said radio transceivers (11) are connected wirelessly or via cables.

Novel tools and techniques are provided for implementing voice monitoring and tracking, and, more particularly, to methods, systems, and apparatuses for implementing voice monitoring and tracking of participants in group settings. In various embodiments, a computing system might receive, from at least one audio sensor among the one or more audio sensors disposed within the first space, voice signals corresponding to voices associated with individuals present within the first space. The computing system might analyze the received voice signals to identify one or more individuals who are present within the first space. The computing system might present, within a user interface of the user device associated with the user, information regarding the identified one or more individuals to assist the user in coordinating discussions among the individuals present within the first space.

An audio cancellation system includes a voice enabled computing system that is connected to an audio output device using a wired or wireless communication network. The voice enabled computing device can provide media content to a user and receive a voice command from the user. The connection between the voice enabled computing system and the audio output device introduces a time delay between the media content being generated at the voice enabled computing device and the media content being reproduced at the audio output device. The system operates to determine a calibration value adapted for the voice enabled computing system and the audio output device. The system uses the calibration value to filter the user's voice command from a recording of ambient sound including the media content, without requiring significant use of memory and computing resources.

Systems, methods, and apparatus for frequency routing based on orientation are disclosed. An example method includes receiving, by a playback device, an audio data stream. The example method includes determining, by the playback device, an orientation of the playback device. The example method includes routing, by the playback device, a first set of frequencies in the audio data stream to at least one of a plurality of speaker drivers based on the first orientation. The example method includes routing, by the playback device, a second set of frequencies in the audio data stream to the at least one of the plurality of speaker drivers based on the second orientation, wherein the first set of frequencies is different than the second set of frequencies.
