Abstract: Digital watermarking is an notable line an eye to patronage of copyright of digital works. It is a exaggerated utilization of bumf hiding line. It embeds encrypted bumf into the digital multimedia, in curtail to guard copyright of works; be found its authenticity and append bumf of works, but it cannot cut back the value of works.Protection of copyright of digital audio works whim be more and more notable along with broad utilization of the mp3 compression norm, and audio watermarking whim be entire of the hottest subjects.

In this writing-paper, we inspection digital audio watermarking in bosom wavelet convert area generally. And then, we reconsideration the watermarking algorithms in DWT area, and bring in a self-adaptive husky watermarking and a lightsome watermarking. At beginning, this writing-paper presents underlying honesty of digital watermarking, actuality, and the shop-worn algorithms of digital audio watermarking.

Lastly, we contemplate a dual watermarking of combining both of them, which embed two watermarks in scads positions in DWT area. The watermarks are binary images which are more intuitionistic than unorganized sequences, and we be sympathetic of prominent cryptogram algorithm and formlessness combination to the watermarking. The assumed results show up that the algorithms are witless, and they fabricate charming robustness, acuteness and inaudibility.
