Spectral Magnitude Adjusted Data Hiding in MCLT Domain of Audio Signal for Robust Acoustic Data Transmission
Data hiding in audio signal enables acoustic data transmission by playing back the data-embedded audio and by recording the signal and extracting the data at receiver like mobile devices. In our previous work, we proposed an audio data hiding system for acoustic data transmission, of which the audio quality and transmission performance are suitable, based on phase modification of the modulated complex lapped transform (MCLT) coefficients. In this paper, we propose the spectral magnitude adjustment (SMA) technique for this data hiding system which enhances both the quality of the dataembedded audio signal and the transmission performance.
