Abstract :
This article mainly researches on the principle of digital audio signal embedded watermarking and the usage of wavelet transform to realize the audio digital watermark embedding and extracting algorithm. This algorithm has good stealth and robustness. The influence of embedded watermarking on the original audio signal can not be found by human perceptual system and can resist the general signal attack.
