Hybrid DWT-SVD audio watermarking

Audio watermarking is a relatively new technology that aims to embed copyright information in audio signals as a proof of their ownership. The driving force behind this technology has been the ever-increasing illegal manipulation of genuine audio products released by the music industry. In this paper, we propose an effective, robust, and inaudible audio watermarking algorithm. The effectiveness of algorithm has been brought by virtue of applying a cascade of two powerful mathematical transforms; the discrete wavelets transform (DWT) and the singular value decomposition (SVD). Reported experimental results demonstrate the effectiveness of the proposed algorithm.
