ACOUSTIC SIGNATURES IN A PLAYBACK SYSTEM

Abstract:

A first computing device is configured to establish a communication path with a second computing device and receive, from the second computing device over the communication path, an indication to begin transmitting an audio tone comprising identifying information for the first computing device, where the audio tone, when detected by the second computing device, causes the second computing device to update a user interface of the second computing device. Based on the received indication, the first computing device begins transmitting the audio tone. The second computing device is configured to detect, via at least one microphone, the audio tone and then, based on the detected audio tone, update the user interface.
