Abstract
An audio/video (A/V) hub that selectively determines one or more acoustic characteristics of an environment that includes the A/V hub is described. In particular, the A/V hub may detect, using wireless communication, an electronic device (such as a speaker) in the environment. Then, the A/V hub may determine a change condition, such as when the electronic device was not previously detected in the environment and/or a change in a location of the electronic device. In response to determining the change condition, the A/V hub may transition into a characterization mode. During the characterization mode, the A/V hub may: provide instructions to the electronic device to playback audio content at a specified playback time; determine one or more acoustic characteristics of the environment based on acoustic measurements in the environment; and store the one or more acoustic characteristics and/or a location of the electronic device in memory.
