In this paper, we proposed digital watermarking algorithms for high quality audio to improve robustness of embedded watermark by adding spread spectrum. The watermark is embedded in each audio frame by adding a perceptually-shaped pseudo-random sequence. The proposed method realized digital audio watermarking technique that audience cannot perceive as a noise by inserting the watermark with using the psychoacoustic model.
