Systems and methods for generating labeled data to facilitate configuration of network microphone devices
Systems and methods for generating training data are described herein. Pieces of metadata captured by a plurality of networked sensor systems can be captured, where each piece of metadata is associated with a specific set of sensor data captured by one of the plurality of networked sensor systems and includes a set of characteristics for the specific set of captured sensor data. A probabilistic model can be generated based on the received metadata and simulations can be performed based upon a training corpus by generating multiple scenarios, and, for each scenario, a scenario specific version of a particular annotated sample is generated by performing a simulation using the particular annotated sample. The scenario specific versions of annotated samples from the training corpus can be stored as a training data set on the at least one network device.
Examples described herein involve switching between two user accounts of a streaming media service. In an example implementation, a playback device stores data representing credentials for multiple user accounts including a first user account of a first streaming audio service and a second user account of the first streaming audio service. The playback device receives instructions to play first audio content from the first streaming audio service and plays back the first audio content by streaming data representing the first audio content from one or more servers of the first streaming audio service using credentials of the first user account. The playback device detects a trigger associated with the first user account of the first streaming audio service and switches from streaming data representing the first audio content using credentials of the first user account to streaming data representing the first audio content using credentials of the second user account.
Embodiments disclosed herein include playback devices configured to operate in one or more playback configurations including configurations individual playback devices play back one or more corresponding channels of multichannel audio content. An audio parameter can be determined based on a distance between playback devices. In some examples, the audio parameter comprises a filter such as a low frequency filter that varies based on at least the distance between the playback devices. After the audio parameter is determined, the playback devices can play back audio content according to the determined audio parameter.
Generative media content (e.g., generative audio) can be played back across multiple playback devices concurrently. A generative content group coordinator device can receive input parameters, which can include sensor data, media content, or other such input. The coordinator device can generate first and second generative media content streams, each of which can be transmitted to first and second playback devices, respectively. The first and second playback devices can play back the first and second streams of generative media content concurrently.
Example systems and techniques disclosed herein facilitate interoperability between different media playback systems referred to herein as a virtual line-in (VLI) media playback system and a native playback system. When a VLI session is created by a VLI sender, a first native playback device can join a VLI group as a VLI receiver. As a VLI receiver, the first native playback device receives audio content and playback commands from the VLI sender to facilitate synchronous playback with other VLI receivers. At the same time, this native playback device can concurrently operate as a native domain group coordinator of a native domain synchrony group. As the native domain group coordinator, the native playback device translates VLI domain audio, control, and timing signals into the native domain and distributes such signals to native domain group members. In this way, the native domain group members can synchronize their playback with the VLI group.

Example techniques described herein relate to a software application that is configured to operate as an add-on software component to audio-playback software on a playback device of a media playback system. An example implementation may involve adding the multiple audio tracks to the playback queue, and before playing back a first audio track, enabling a first add-on component to audio-playback software. The first add-on component corresponds to a first remote source and enabling this component causes a first modification to an equalization of the playback device. The example implementation may also involve before playing back a second audio track, enabling a second add-on component to the audio-playback software. The second add-on component corresponds to the second remote source and enabling this component causes a second modification to the equalization. Enabling the second add-on component disables the first add-on component if enabled.

Disclosed herein are computing devices, including playback devices, that are configured to facilitate re-joining of playback and other devices to a bonded zone based on the specific context relating to how the playback and other devices previously left the bonded zone. The computing devices may determine that playback devices that had been previously bonded in the bonded zone are now capable of communicating with each other again. The computing devices may proceed to identify how and/or why the playback devices previously left the bonded zone. Based on how and/or why the playback devices previously left the bonded zone, the computing devices may determine whether one or more of the playback devices should re-join the bonded zone. For playback devices to be re-joined to the bonded zone, the computing devices may determine audio content to be played back by one or more playback devices of the bonded zone.
Disclosed herein are systems and methods for proximity-based power management for audio playback devices. In a first mode, a portable audio playback device plays back audio content in full. In a second mode, the portable playback device plays back only a first portion of the audio content itself and routes a second portion of the audio content to a nearby playback device, which may be stationary or portable. The portable playback device can transition between the first mode and the second mode based on a proximity parameter of the portable playback device and/or the nearby playback device, a power parameter of the portable playback device and/or the nearby playback device, or a grouping parameter of the portable playback device and/or the nearby playback device.
An example method for facilitating resolution of Internet Protocol (IP) address conflicts involves obtaining a first IP address from a host device; monitoring, by a playback device, an input port of the host device for receiving messages and thereby detecting that the host device has received a message comprising a first lease renew request for a second IP address from a device other than the playback device; determining that the first IP address matches the second IP address; after determining that the first IP address matches the second IP address, obtaining a third IP address from the host device, wherein the third IP address is different from the first IP address and the second IP address; and after obtaining the third IP address, (i) obtaining audio content from at least one cloud server via the host device and (ii) playing back the audio content using at least one audio amplifier.
An input at a physical interface of a first playback device is detected. The input may indicate a playback command. Via the first playback device, the second playback device is determined to be currently playing media content. Based on determining that the second playback device is currently playing media content and based on receiving the input at the physical interface, the first playback device is caused to play the media content synchronously with the second playback device.
A multimedia controller for controlling and displaying zones in a multi-zone system is provided. In one example the controller provides a user interface for multiple zones of a media playback system comprising multiple playback devices. The controller identifies respective states associated with each zone of the multiple zones and detects an input to display a list of the multiple zones. In response to detecting the input, the controller determines an order of the multiple zones within the list of the multiple zones and displays, via the user interface, the list of the multiple zones, wherein the list of the multiple zones identifies each zone of the multiple zones in the determined order.

In one aspect, a computing device is configured to, while operating as a control device of a networked media playback system that includes a first set of network devices and a second set of network devices, (i) transmit a first message to each network device in the first set of network devices, wherein the first message comprises a command to, at a first time, temporarily disconnect from the computing device via a particular communication protocol, (ii) transmit a second message to each network device in the second set of network devices, wherein the second message comprises a command for the network device in the second set of network devices to, at a second time, test connectivity with the computing device; and (iii) after the second time, determine whether each network device in the second set of network devices was connected to the computing device.
In an example implementation, a method may involve, while a first zone and a second zone of a media playback system are playing back respective media, receiving data indicating the occurrence of a first trigger condition. The method may also involve, based on the received data, modifying respective volume limits of the first zone and the second zone, wherein modifying the volume limit causes first volume levels that exceed the second limit to be reduced to respective second volume levels that are at or below the second limit. The method may also involve receiving data indicating the occurrence of a second trigger condition. The method may further involve, based on the received data, modifying the respective volume limits of the first zone and the second zone from the second limit to the first limit.

Example implementations may involve using a prompt to prevent inadvertent control or playback of audio content. When a mobile device receives input data indicating a command to play back audio content on a first playback device, the mobile device determines whether the mobile device is in proximity to the first playback device. If the mobile device determines that the mobile device within a given proximity to the first playback device, the mobile device transmits, via the network interface, one or more commands to instruct the first playback device to play back the audio content. However, if the mobile device determines that the mobile device outside the proximity, the mobile device displays a prompt indicating that the mobile device is the outside the given proximity to the first playback device and a selectable control that, when selected, transmits the one or more commands to play back the audio content.

Example techniques relate to transferring playback between playback devices within a network media system. In an example, while a first playback device is playing a first audio track of a playlist, a device displays a representation of metadata for the first audio track, transport controls to control playback, a volume control to control playback volume, and a selectable control that, when selected, causes display of a zone selection interface. The device receives input data representing a selection of the selectable control and modifies the control interface to display the zone selection interface, which includes indications of second playback devices and respective second selectable controls. The device receives input data representing selections of one or more second selectable controls, which correspond to one or more particular second playback devices and then transfers playback to the one or more particular second playback devices.

Example techniques may involve controlling a passive radiator. An implementation may include a device receiving, via a network interface, audio content and generating an audio signal representing the audio content. Generating the audio signal involves modifying portions of the audio content to limit excursion of the speaker driver to less than an excursion limit when a forward prediction model indicates that the portions of the audio content are predicted to cause the speaker driver to move beyond the excursion limit. While playing back the generated audio signal via the audio stage, the device detects, via a sensor, clipping of the speaker driver and generates a feedback signal based on the detected clipping of the speaker driver. The device adjusts the forward prediction model based on the generated feedback signal.
