AUDIO FORENSIC USING DWT-LSB

Many effective watermarking algorithms have been proposed and implemented for digital images and digital video, however, few algorithms h ave 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 audio watermarking algorithm based on DWT-LSB is proposed. The DWT transformation decomposes the audio signal into several sub bands, enabling developers to locate the most appropriate sub-bad to embed. The watermark bits are embedded into the high- resolution sub-band by using LSB algorithm, so the satisfactory robustness and the imperceptibility performances are obtained
