Digital watermarking is a technique of embedding and extract information into the multimedia. Many effective watermarking algorithms have been proposed and implemented for digital images and 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 an imperceptible and embedding blocking code optimization truncation algorithm based on the discrete wavelet transform is proposed. Performance of the algorithm has been evaluated extensively,and simulation results are presented to demonstrate the imperceptibility and robustness of the proposed algorithm.
