Abstract: Some disclosed methods involve causing one or more loudspeakers in an audio environment to emit sound and receiving microphone signals from one or more microphones in the audio environment corresponding to an acoustic response of the audio environment to the emitted sound. Some disclosed methods involve detecting, by the control system, a change of the acoustic response of the audio environment. Some disclosed methods involve changing one or more aspects of media processing for media played back by one or more devices in the audio environment based, at least in part, on the change of the acoustic response of the audio environment. Alternatively, or additionally, some disclosed methods may involve changing the lighting in the environment, changing a gain of one or more microphone signals, locking or unlocking one or more devices, or combinations thereof, based at least in part on the change of the acoustic response.
