Abstract: This paper introduces a new technique of audio watermarking based on the property of the human auditory system(HAS) and MP3 coding, in which magnitudes of the frequency components below hearing thresholds are modified for watermark embedding. Neither the host signal nor any synchronization information is needed on the extraction side. Experimental results show that the proposed scheme can achieve high imperceptibility and satisfactory robustness against various common attacks.

Key words: audio watermarking, hearing threshold, psychoacoustics auditory model
