Abstract
Methods and systems for improved data transmission using audio transmissions are provided. In one embodiment, a method is provided that includes receiving an audio transmission at. Audio symbols may be identified within the audio transmission, and a magnitude and phase for each of the symbols may be identified. Based on the magnitudes and phases, corresponding data values may be identified for each of the audio symbols and may be combined to form a data payload of the audio transmission.
