| Abstract: | A data hiding technique in a sound wave imperceptibly can be used for a communication system beyond the audio watermarking. The transmitter with a loudspeaker can send the data by playing the sound wave, and the receiver like mobile phone can detect the message using a microphone. This paper proposes an acoustic data transmission system based on the modulated complex lapped transform (MCLT). In the proposed system, data is embedded in an audio wave file by modifying the phases of the MCLT coefficients of the audio wave. The perceived quality of the data-embedded audio wave is almost similar as the original audio. The proposed system is sufficient to deliver short text messages without any additional hardware devices. |
