perceptual audio coding, the quality of codecs often is evaluated by comparing an original signal, called reference, with its coded version. Naturally, this general principle applies to the quality evaluation of a watermarking system as well. Instead of evaluating the coded version (as is the case in codec quality assessment) the watermarked version is analyzed. First the applied …

information reduces the audio signal quality. Discrete Cosine Transform The discrete cosine transform (DCT) is well known technique for audio and image watermarking. The DCT breaks the image into spectral sub bands (small parts) considering the image and audio quality. The DCT is similar to Discrete Fourier Transform because it transforms the

Work done on the digital audio watermarking includes the ways of evaluating various algorithms. An algorithm-independent framework for comparing digital watermarking algorithm with respect to bit rate, perceptual quality, computational complexity, and robustness to signal processing was proposed (Gordy et al, 2000). The
