Audio Watermarking Approach Based on Energy Relation in Wavelet Domain

WANG Xun,PENG Hong(School of Mathematics & Computer Engineering,Xihua University,Chengdu 610039 China)  
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.
