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: Examples described herein relate to transitioning a playback session between portable playback devices such as “smart” headphones, earbuds, and handheld speakers with playback devices of a zone-based media playback system. Exemplary techniques facilitate continuity of playback when transitioning between locations (e.g., from at home to on-the-go or vice versa) or between listening paradigms (e.g., personal or out-loud playback of audio content). An example implementation includes detecting a swap trigger, determining the source playback device(s) and target playback device(s), and performing a playback session swap between the source playback device(s) and target playback device(s).

Abstract: Generative media content (e.g., generative audio) can be played back across multiple playback devices concurrently. A coordinator device can receive a multi-channel stream of media content, with at least some channels comprising generative media content. The coordinator device transmits each of the channels to a plurality of playback devices. A first playback device plays back a first subset of the channels according to first playback responsibilities and a second playback device plays back a second subset of the channels according to second playback responsibilities. The first and/or second playback responsibilities can be dynamically modified over time, for example in response to one or more input parameters.

Abstract: Example techniques involve invoking voice assistance for a media playback system. In some embodiments, a NMD stores in memory a set of command information comprising a listing of playback commands and associated command criteria. The NMD captures a voice input and detects inclusion, within the voice input, of one or more particular playback commands from among the playback commands in the listing. In response, the NMD selects a local voice assistant that supports (a) one or more additional playback commands relative to a cloud-based VAS and (b) fewer non-playback commands relative to the cloud-based VAS, determines, via the local voice assistant, an intent in the captured voice input, and performs a response to the determined intent. The NMD foregoes selection of the cloud-based VAS when the local voice assistant is selected.

Abstract: Turntable control systems are disclosed. A playback device can include an analog audio source component such as a turntable. The playback device is configured to cause playback of first audio based on analog audio signals generated by the analog audio source component. Based on an indication that analog audio signals are no longer being generated, the playback device requests, via a network interface, audio content from one or more remote computing devices. The request can include identifying related content based on the first audio. The playback device receives, via the network interface, second audio content from, and causes playback of second audio based on the second audio content.

Abstract: Generative media content (e.g., generative audio) can be dynamically generated based on various inputs, which can include blockchain data. A playback device accesses blockchain data stored via a distributed ledger and generates media content based at least in part on the blockchain data. The playback device can access a library of pre-existing media segments and arrange a selection of pre-existing media segments from the library for playback according to a generative media content model and based at least in part on the blockchain data. The generated media content can then be played back via the playback device.

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.

Abstract: Example techniques may involve tuning a music discovery dial. An implementation may include displaying, on the touch-sensitive circular graphical display, a circular graphical user interface including multiple wedge-shaped selectable regions arranged around the circumference of the circular graphical user interface, each wedge-shaped selectable region corresponding to a respective streaming audio channel. The implementation may include detecting a touch input in a circular motion to the touch-sensitive circular graphical display and causing a paired playback device to play back an audio content snippet corresponding to each selectable regions that the touch input enters. The implementation may further include switching the playback device from playing back a given pre-cached audio content snippet to playing back the full audio track from one or more servers of a streaming audio service.

Abstract: Example techniques may involve multiple calibrations for a playback device. In an example implementation, a playback device plays back audio content according to a first calibration via the one or more audio amplifiers. The playback device detects that an arrangement of one or more listeners relative to the first playback device has changed from a first arrangement to a second arrangement. Based on detection that the arrangement of one or more listeners relative to the first playback device has changed from the first arrangement to the second arrangement, the playback device applies a second calibration to playback by the first playback device.
