this paper by using the Empirical Mode Decomposition (EMD) developed an algorithm for advance adaptive audio watermarking. The audio signal is classified into frames and each one is decomposed adaptively, by EMD, into intrinsic oscillatory components which is as called Intrinsic Mode Functions (IMFs). The codes are embedded into the extrema of last splitted IMF because last IMFs are most stable frequency component under various attacks and so protects quality of the host signal. A low frequency mode stable under different attacks and preserving audio perceptual quality of the host signal. The data embedding rate of the proposed algorithm is 46.8–51.3b/s. The comparison analysis shows that our method has good performance than watermarking schemes reported recently.
