摘要
提出了一种基于小波变换的音频数字水印算法,该算法具有良好的鲁棒性,并且嵌入水印后的音频信号没有引起人耳所感知到的品质变化.算法能抵抗常见的信号处理和音频压缩编码.数值仿真显示了算法的有效性.
A kind of digital audio signal watermarking algorithm is proposed, which has stronger robustness. The influence of embedded watermarking on the original audio signal can not be found by the human perceptual system. The proposed algorithm can resist the general signal processing and audio compressing codes. Computer simulation shows the effiectiveness of the proposed algorithm.
