Synchronization attack is one of the key issues of digital audio watermarking. In this paper, a robust digital audio watermarking algorithm in DWT (Discrete Wavelet Transform) and DCT (Discrete Cosine Transform) domain is presented, which can resist synchronization attack effectively. The features of the proposed algorithm are as follows: (1)More steady synchronization code and new embedded strategy are adopted to resist the synchronization attack effectively. (2)The multi-resolution characteristics of DWT and the energy- compression characteristics of DCT are combined to improve the transparency of digital watermark. (3)The algorithm can extract the watermark without the help of the original digital audio signal.
