Digital watermarking is the process of embedding copyrighting information into digital media frame. They are preferred to be imperceptible to the end users. In this paper we propose a novel audio watermarking technique. The algorithm proposed uses multilevel wavelet decomposition, DCT (Discrete Cosine Transform) and SVD (Singular Value Decomposition) to achieve robustness and inaudibility. Audio Quality parameters (metrics) are calculated and analyzed after applying various attacks on the watermarked signal.
