Abstract-- Widely available speakers and microphones in elec-
tronic devices motivate the use of generic audio hardware to
establish acoustic communication links. Acoustic communication
with generic hardware requires software modems for data modu-
lation and demodulation. The resulting acoustic communications
system paves the way for cheap and easily deployable underwater
acoustic sensor networks through the use of audio hardware
built in to the sensor modules. In this paper, we explore the
potential of the acoustic communication system for both aerial
and underwater environments. Our experiments profile both
media with generic microphones and speakers. An initial test
