摘　　要： 利用音频信号中相邻音频帧之间的高相关性,提出了一种基于相邻两音频帧在小波域的能量大小关系嵌入水印的新算法。结合每两帧之间的能量均值与能量差值特征,以确定用于嵌入水印的音频帧。实验结果表明该方法有较好的鲁棒性和不可感知性,能抵抗常见的信号处理攻击。 Due to the high relevance between adjacent audio frames, a novel audio watermarking scheme based on energy relation of two consecutive frames in wavelet domain is proposed in this paper. To enhance the robustness and auditory quality, the energy mean and the energy difference in every two consecutive frames are analyzed, and the frames of the embedded watermark are chosen. The experimental results show that the proposed algorithm will improve the robustness of watermark without losing auditory quality, and is robust for common audio data manipulation.
