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.

Transmitting data using audio transmissions and quadrature amplitude modulation and associated equalization strategies

Methods and systems for controlling the receipt and transmission of audio transmissions are provided. In one embodiment, a method is provided that includes selecting a first audio channel and transmitting a first audio transmission using the first audio channel. A second audio transmission may then be received that contains an acknowledgment of the first audio transmission. In certain instances, the second audio transmission may be received on the first audio channel. If a second audio transmission is received on the first audio channel, it may be determined that the first audio transmission was successfully received by another computing device.
