The method of audio digital watermark based on dither modulation is dedicated to the problem which a watermark directly inserted into low frequence part made out sensitive noise,being subsection for audio signal by audio mesk effect,taking low frequence part of discrete wavelet transform,and inserting into scrambling watermark by dither modulation.
基于扰动调制的音频数字水印方法,通过按声音掩蔽效应先对音频信号分段,并取离散小波变换的低频成分,按扰动调制技术嵌入已置乱的水印信息,解决了直接在低频成分嵌入水印信号所带来的敏感噪声问题。
