A method of determining whether a first playback device is to rejoin a group is disclosed. The method comprises playing back, by the first playback device, media content in synchrony with at least a second playback device, wherein the first and second playback devices are playing back the media content as members of a group. While playing back the media content, and after a loss of power at the first playback device, the method comprises stopping, by the first playback device, playback of the media content. After the loss of power, and after a resumption of power to the first playback device the method comprises automatically determining to rejoin the group and joining the first playback device to the group.

A method for a control device is disclosed. The method comprises configuring the control device to control a first networked device and while controlling the first networked device and while operating in a first mode, receiving, via the control device, first input data, the first input data indicative of a command to control an illumination device of the first networked device. After receiving the first input data, the method comprises controlling the illumination device of the first networked device. While controlling the first networked device and while operating in a second mode, the method comprises receiving, via the control device, second input data, the second input data indicative of a command to control a playback device of the first networked device. After receiving the second input data, the method comprises controlling the playback device of the first networked device.

An information processing device includes circuitry that detects a change in a position of a person. The circuitry also changes a position of a virtual sound source in accordance with the change in the position of the person and outputs a sound through wave field synthesis so that a spatial sound field is transmitted via a plurality of speakers.

A sound signal processing method includes: obtaining a sound signal; obtaining impulse response data that was measured in a predetermined space before the sound signal is obtained; generating an early reflected sound control signal not including a reverberant sound by convolving impulse response data of an early reflected sound among the obtained impulse response data into the obtained sound signal.

The systems and methods described relate to the concept that smart devices can be used to: sense various types of phenomena like sound, blue light exposure, RF and microwave radiation, and, in real-time, analyze, report and/or control outputs (e.g., displays or speakers). The systems are configurable and use standard computing devices, such as wearable electronics (e.g., smart glasses), tablet computers, and mobile phones to measure various frequency bands across multiple points, allowing a single user to visualize and/or adjust environmental conditions.
