To research the hidden and embedded quantity of the audio watermark.Audio watermark algorithm based on elevate wavelet domain transform is proposed which applied the theory of matrix coding to realize the secret data embedded.The algorithm made lifting wavelet transform with initiation audio frame,using masking properties of human auditory system to find the right embedded frame,extraction of the host signal enhance wavelet coefficients of the LSB,and using matrix coding realize secret data embedded.The experiment shows that because the algorithm using human auditory masking,therefore,this algorithm have a more efficient,safe,hidden properties than the average wavelet domain LSB algorithm.And the algorithm has a good property of robust and imperceptible.
