Abstract
A method of acoustic-based data distribution includes recognizing a high frequency analog acoustic signal by an acoustic receiver of a mobile computing device. The high frequency analog acoustic signal includes a stream of sound that is outside the audible spectrum of a human, and contains encoded data. An analog-to-digital converter of the mobile computing device converts the recognized high frequency analog acoustic signal to a digital acoustic signal, and then a processor of the mobile computing device analyzes the digital acoustic signal to obtain the encoded data from the digital acoustic signal. The processor decodes the encoded data obtained from the digital acoustic signal to obtain information, and then a display device of the mobile computing device displays the information on the mobile computing device.
