With the increasing usage of digital multimedia, protecting the data from illegal copyright infringement, fingerprinting and other malicious attacks is also increasing. Digital watermarking is a technique which provide protection of digital information against illegitimate exploitations and allocation. Digital audio watermarking technique is a process of embedding perceptually transparent digital information into the original host signal without affecting the signal quality. Watermarking techniques can be applied on various multimedia data such as text, audio, images and video for various application. n this paper, we propose an audio watermarking algorithm based on two mathematical functions: Discrete Wavelet Transform (DWT) and Singular Value Decomposition (SVD). These algorithms performance is validated in the presence of the standard watermarking attacks. A new audio signal framing, DWT matrix formation and embedding methods are proposed and successfully implemented to improve robustness and capacity. The experimental results show that the method has very high capacity and provides robustness against common audio signal processing
