Digital watermarking is a technique to protect ownership and copyright protect of multimedia content. Many effective water marking algorithms have been proposed and implemented for audio signals. This is due to the fact, the human audio system is far more complex and sensitive than the human visual system. In this paper, an audio watermarking algorithm based on Lifting Wavelet Transform (LWT) is proposed. The LWT transformation decomposes the audio signal into detailed and approximation coefficients, enabling developers to locate the most appropriate location to embed the data. The watermarking data is embedded into the approximation coefficients of audio file by using an embedding technique. Inorder to obtain the robustness and imperceptibility and the results will be compared with the DWT transformed audio watermarking signals.
