The audio watermarking system based on wavelet transform algorithm

This paper puts forward a method based on the wavelet transform of digital audio watermarking algorithm, using the method of Haar wavelet base to embed watermark, and don´t need the original audio carrier signal when extracting watermark, realized the blind extraction audio watermark, the simulation results show that this algorithm has a certain transparency and can resist attacks including re-sampling, low-pass filtering, adding noise, shearing, compressing and so on, It has a good robustness.
