In this paper, the authors present a novel watermarking procedure to embed for copyright protection and authentication into digital audio by directly changing the audio samples then after modifying the audio signals. The modified audio signals are divided into no. of samples each sample is decomposed adaptively by the method of novel Empirical Mode Decomposition (EMD).those decomposed samples after decomposition called as a Intrinsic Mode Functions (IMFs), In this Intrinsic Mode Function (IMF) the low frequency mode table under different attacks is presented and then after audio perceptual quality of the original audio signal is preserved.
