Abstract
A method includes receiving an audio signal at a mobile computing device and determining whether the audio signal is within a particular frequency range using an application executing at the mobile computing device. When the audio signal is within the particular frequency range, the audio signal may be processed to determine speaker location data encoded within the audio signal that indicates a location associated with a speaker generating the audio signal. A message including information associated with the speaker location data may be sent from the mobile computing device to a server, and item data from the server may be received at the mobile computing device. The item data is related to an item that is located proximate to the speaker, and information descriptive of the item may be displayed at the mobile computing device.
