This paper presents a frame based audio watermarking scheme using spread spectrum technique in Discrete Wavelet Transformation (DWT) domain. Here some of the existing spread spectrum (SS) watermarking schemes are implemented and analyzed. A new technique is presented where embedding is performed using SS technique in DWT domain. A comparative study is performed with the existing techniques by calculating bit error rate and Signal to Noise Ratio (SNR) values. Experimental result shows that the… CONTINUE READING
