%X In this paper, a robust adaptive digital audio watermarking scheme in the hybrid domain is presented. The features of the proposed algorithm are as follows: 1)More robust synchronization codes and a new embedded strategy are adopted to resist the attack effectively. 2)The multi-resolution characteristics of discrete wavelet transform(DWT) and the energy-compression characteristics of discrete cosine transform(DCT) are combined to improve the transparency of digital watermark. 3)The adaptive quantization steps are identified according to human auditory masking. 4)The algorithm can extract the watermark without the help of the original digital audio signal. Experimental results show that the proposed watermarking algorithm is imperceptible and robust against various signal processings such as re-sampling, re-quantifying, noising adding, low pass filtering and cropping. Especially, our audio watermarking scheme is remarkably effective in resisting MP3 compression.
