In this paper a new audio watermarking technique Empirical Mode Decomposition (EMD) is introduced. The audio signal is first split into frames and each one is then decomposed by EMD to get intrinsic periodic elements known as Intrinsic Mode Functions (IMFs). The combination of watermark and synchronization code is embedded into the last IMF, which is most stable frequency component under different attacks and protects quality of the host signal. So this methodology is applied to any image and audio signals. Experimentation has given the physical marking and its detection to protect audio on different attacks.
