Example techniques relate to audio playback device calibration. Example playback devices described herein may utilize one or more techniques for calibration, which may be implemented as various calibration procedures. In some implementations, the example media playback system may support multiple types of calibration, perhaps with different calibration procedures being used for different types of playback devices (e.g., with different capabilities) or in different situations (e.g., with or without user involvement).
Example techniques may involve calibration with multiple recording devices. An implementation may include a mobile device receiving data indicating that a calibration sequence for multiple playback devices has been initiated in a venue. The mobile device displays a prompt to include the first mobile device in the calibration sequence for the multiple playback devices and a particular selectable control that, when selected, includes the first mobile device in the calibration sequence. During the calibration sequence, the mobile device records calibration audio as played back by the multiple playback devices and transmits data representing the recorded calibration audio to a computing device. The computing device determines a calibration for the multiple playback devices in the venue based on the data representing the calibration audio recorded by the first mobile device and data representing calibration audio recorded by second mobile devices while the multiple playback devices played back the calibration audio.
Example techniques relate to re-establishing connectivity of playback devices. In an example implementation, a first playback device determines that a first access point has been replaced with a second access point, wherein the first playback device previously established a valid network connection over the first WLAN using first network parameters. The first playback device connects to the second access point, the second access point providing a second WLAN. The first playback device requests, via the wireless network interface from the second access point, an IP address in a second subnet, the second subnet covering a different range of IP addresses than the first subnet and establishes a network connection over the second WLAN using second network parameters stored in the data storage of the first playback 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 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.

G06F 3/04883 - Techniques d’interaction fondées sur les interfaces utilisateur graphiques [GUI] utilisant des caractéristiques spécifiques fournies par le périphérique d’entrée, p.ex. des fonctions commandées par la rotation d’une souris à deux capteurs, ou par la nature du périphérique d’entrée, p.ex. des gestes en fonction de la pression exer utilisant un écran tactile ou une tablette numérique, p.ex. entrée de commandes par des tracés gestuels pour l’entrée de données par calligraphie, p.ex. sous forme de gestes ou de texte
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.

Based on a credential, an access level of a playback queue for a first control interface and a first subset and second subset of media items in the playback queue may be determined. Media items in the playback queue that were added via a second control interface may be included in the first subset. Media items that were added via a control interface different from the second control interface may be included in a second subset. Information may be provided which identifies the first subset of the media items in the playback queue and the second subset of the media items in the playback queue.
