In this paper a new adaptive audio watermarking algorithm based on Empirical Mode Decomposition(EMD) is introduced. The audio signal is divided into frames and each one is decomposed adaptively, by EMD, into intrinsicoscillatory components called Intrinsic Mode Functions (IMFs). The watermark and the synchronization codes are embeddedinto the extrema of the last IMF, a low frequency mode stable under different attacks and preserving audio perceptual qualityof the host signal. The data embedding rate of the proposed algorithm is 46.9–50.3 b/s. relying on exhaustive simulations, weshow the robustness of the hidden watermark for additive noise, MP3 compression, re quantization, filtering, cropping andresampling. The comparison analysis shows that our method has better performance than watermarking schemes reportedrecently.
