DIGITAL WATERMARKING OF AUDIO SIGNALS USING A PSYCHOCOUSTIC AUDITORY MODEL AND SPREAD SPECTRUM THEORY.

All three, Discrete Wavelet Transform (DWT) - Singular Value Decomposition (SVD) and Adaptive Tabu Search (ATS) have been used as mathematical tools for embedding data into an audio signal. In this paper, we present a new robust audio waterma
