DWT-Based Audio Watermarking

TMany effective watermarking algorithms have been proposed and implemented for digital images and digital video, however, ‎few algorithms have been proposed for audio watermarking. This is due to the fact that, the human audio system is far more ‎complex and sensitive than the human visual system. In this paper, we describe an imperceptible and robust audio ‎watermarking algorithm based on the discrete wavelet transform. Performance of the algorithm has been evaluated ‎extensively, and simulation results are presented to demonstrate the imperceptibility and robustness of the proposed ‎algorithm
