AB  - This paper presents a method of aerial acoustic communication in which data is modulated using OFDM (Orthogonal Frequency Division Multiplexing) and embedded in regular audio material. It can transmit at a data rate of about 1kbps, which is much higher than is possible with other data hiding techniques. In our method, the high frequency band of the audio signal is replaced with OFDM carriers, each of which is power-controlled according to the spectrum envelope of the audio signal. The method enables the transmission of short messages from loudspeakers to mobile handheld devices without significantly degrading the quality of the original voice or music signals.
