Abstract: This paper proposes a new algorithm of digital audio watermarking based on the idea of SCS. This algorithm can design the embedding parameters constrained by performance of watermarking. The paper adds the watermarking on space domain and wavelet domain respectively, and compares its performance against the attack of additive noise ,MP3 compression and resample. Computer simulation proves that this algorithm is effective and stable.
