Audio Watermarking With the Help of EMD: A Review

Abstract
Watermarking an audio signal is a very crucial thing. So a new 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 components known as Intrinsic Mode Functions (IMFs). The combination of watermark and synchronization code are 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. It has given the physical marking and its detection to protect audio on different attacks. Index Terms— Empirical mode decomposition, Intrinsic Mode Function, synchronization code, amplitude modulation, signal to noise ratio, frequency modulation.
