Systems and methods for noise reduction using synthetic audio are disclosed. One or more playback devices include first microphone(s) (e.g., air-conduction microphone(s)) and second microphone(s) (e.g., bone-conduction microphone(s)). In operation, based on a user voice input, first and sound data streams are captured via the first and second microphone(s), respectively. The first sound data stream is evaluated to determine whether a noise threshold is exceeded. While the noise threshold is not exceeded, a synthetic sound data model is trained based on the first and second sound data streams. An audio output stream based on the first sound data stream is communicated to at least one second playback device. When noise is detected in the first sound data stream, a synthetic audio stream is mixed into the output audio stream. The synthetic audio stream can be produced based on the synthetic sound data model.

Noise reduction using synthetic audio

Disclosed herein are systems and methods for charging batteries of audio playback devices. An example method performed by a media playback system includes receiving power from a first power source to charge a first power storage of a first playback device according to a first charging scheme, and receiving power from a second power source to charge a second power storage of a second playback device according to a second charging scheme. The system receives an instruction to form a group for synchronous audio playback, and obtains one or more power parameters associated with the first playback device and/or the second playback device. After receiving the instruction to form the group, the system modifies the first charging scheme based on the one or more power parameters, and then receives power from the first power source to charge the first power storage according to the modified first charging scheme.

Systems and methods of charging playback device batteries

An example video communication device is configured to (i) receive, from a computing platform via a wide area network (WAN), video and audio content corresponding to a video call, (ii) render the video content via at least one graphical display and render the audio content via at least one speaker, (iii) while rendering the video and audio content, determine that a user of the video communication device is located more closely to an audio playback device than to the video communication device, where the audio playback device is connected to the video communication device via a local area network (LAN), and (iv) based on determining that the user is located more closely to the audio playback device than to the video communication device, transmit the received audio content to the audio playback device via the LAN and cause the audio playback device to play back the audio content.

Media player device

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.
