Audio watermarking is the process of adding the information into audio files in such a way that the hidden information can be used to recognize the owner of the file as well as the quality of the audio signal will not be hampered. Many algorithms for

The Discrete Wavelet Transform (DWT) is a transformation that can be used to analyze the temporal and spectral properties of non-stationary signals like audio. In this paper we describe some applications of the DWT to the problem of extracting in
