A DCT Domain Audio Watermarking Algorithm Based on Human Auditory Masking Properties

WU Jun①,GU Ji-hua①,TAO Zhi①,ZHAO He-ming②,HUANG Chuan-xia①(①School of Phys.Sci.and Tech.,Suzhou Univ.,Suzhou Jiangsu 215006,China;②Dept.of Electron,School of Information,Suzhou Univ.,Suzhou Jiangsu 215006,China)  
This paper presents an audio watermarking algorithm in DCT domain based on human auditory masking properties.First the masking threshold of each frame of audio signal is calculated according to psychoacoustic model,and then the watermark signal is adaptively embedded in the DCT coefficients whose corresponding frequency components are under the masking thresholds by using the quantification method.Simulation results indicate that: as compared with the traditional DFT method,the algorithm has better transparency and robustness.
