%X A new watermarking algorithm based on DWT transform was proposed to offer copyright protection for digital audio signals. A digital watermark is embedded into the significant wavelet coefficients repeatedly. The experimental results show that the imbedded watermark has good imperceptibility and robustness against common signal processing manipulations and the watermark can be extracted without original data.
