Embodiments are provided for intelligently activating an amplifier in a playback device based on proximity detection. The playback device may be in a quasi-idle state when the playback device is not rendering media content. The quasi-idle state of the playback device may involve an amplifier in the playback device being inactive, while some other components or modules of the playback devices remain active. The playback device may include a proximity sensor configured to detect movement relative to the playback device. If movement is detected indicating that a user input to cause the playback device to render media content is anticipated, the amplifier may be pre-emptively activated such that the playback device enters an active state from the quasi-idle state. In some cases, the playback device may send a message to one or more other playback devices to cause the other playback devices to enter an active state.

Intelligent amplifier activation

Techniques for shaping sound based on a speaker orientation are disclosed. In an embodiment, an audio data stream is obtained by a zone player having one or more speaker drivers, an orientation of the zone player is determined, and sound is reproduced by the zone player based on the orientation. The sound may be further shaped based on other states of the zone player in addition to orientation. The overall sound may be shaped from one zone player or from a collection of zone players.

Position-based playback of multichannel audio

An example computing device is configured to transmit playback preference tracking information to a media service registered with a media playback system and, after transmitting the playback preference information, (a) determine a first time boundary corresponding to a beginning of a zone scene that causes a first playback device in a first zone of the media playback system to be configured for synchronous playback of media with a second playback device in a second zone of the media playback system, (b) determine a second time boundary corresponding to an end of the zone scene, and (c) transmit, to the media service registered with the media playback system, a request to remove playback preference tracking information received between the first time boundary and the second time boundary.

Smart music services preferences

Example techniques describe may facilitate a playback device applying a determined audio setting. An example implementation involves a first playback device receiving, over an unsecure network, a message indicating that a second playback device is available to join a playback network, wherein the first playback device is connected to the playback network. Based on a pre-existing configuration table, the first playback device determines an audio setting corresponding to a playback configuration for the second playback device, the playback configuration including the second playback device playing back audio synchronously with the first playback device in the playback network. The first playback device transmits, to the second playback device, one or more messages instructing the second playback device to apply the determined audio setting upon joining the playback network. Applying the determined audio setting includes forming the playback configuration with the first playback device to play back audio synchronously.

Configuration of playback device audio settings

Example techniques involve suppressing a wake word response to a local wake word. An example implementation involves a playback device receiving audio content for playback by the playback device and providing a sound data stream representing the received audio content to a voice assistant service (VAS) wake-word engine and a local keyword engine. The playback device plays back a first portion of the audio content and detects, via the local keyword engine, that a second portion of the received audio content includes sound data matching one or more particular local keywords. Before the second portion of the received audio content is played back, the playback device disables a local keyword response of the local keyword engine to the one or more particular local keywords and then plays back the second portion of the audio content via one or more speakers.

Wake-word detection suppression

Embodiments described herein involve an auxiliary zone contributing audio to a primary zone. In an example implementation, a network media system determines that a first zone in the network media system is playing back a first type of audio content and that a second zone in the network media system is not playing back audio content. While the first zone is playing back the first type of audio content and the second zone is not playing back audio content, the network media system forms a temporarily playback configuration. In the temporary playback configuration, the first zone plays back primary audio content including full frequency range audio content and the second playback device of the second zone plays back auxiliary audio content including low frequency range audio content.

Immersive audio in a media playback system

A first playback is configured to (i) while connected to a local data network via a network interface using a first wireless networking protocol, receive a command to begin communicating with a second playback device in a group of playback devices for synchronous playback, (ii) based on the received command, begin communicating with the second playback device, (iii) determine that the second playback device is connected to the local data network using a second wireless networking protocol, (iv) based the determining, cause the second playback device to operate as a group coordinator of the group of playback devices, wherein the group coordinator (a) receives audio content from an audio source, and (b) transmits the audio content to the first playback device during rendering of the audio content by the group of playback devices, and (v) thereafter, receive the audio content from the second playback device.

Group coordinator selection

Examples disclosed herein include a social-media computing system receiving, from a first computing device, a first message indicating that a media playback system is associated with a first social-media account; and based on the received first message, sending, to a second computing device associated with a second social-media account, a second message indicating that the media playback system is associated with the first social-media account. The examples may also include the second computing device receiving, from the social-media computing system, the second message; and based on the received second message, causing display of an indication of the association between the media playback system and the second social-media account.

Indicating an association between a social-media account and a media playback system

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.

Voice control of a media playback system

Disclosed embodiments include systems and methods for position-based playback of multichannel audio. Some embodiments include (i) receiving, via a network interface of a first playback device, an indication of a position of a second playback device, (ii) determining, based on the received indication of the position of the second playback device, an audio characteristic of the first playback device, and (iii) playing back, via one or more transducers associated with the first playback device, a first portion of media content according to the determined audio characteristic in substantial synchrony with playback, via the second playback device, of a second portion of the media content.

Disclosed embodiments include systems and methods for position-based playback of multichannel audio. Some embodiments include (i) determining first and second positions of first and second playback devices, respectively, (ii) receiving media content comprising multichannel content, (iii) generating first audio according to a first sound characteristic based on the received multichannel audio content and the first position of the first playback device, (iv) generating first audio according to a first sound characteristic based on the received multichannel audio content and the first position of the first playback device, and (v) causing synchronous playback of the generated first audio via the first playback device and the generated second audio via the second playback device.
