In this paper, a watermarking scheme for both monophonic and stereophonic audio files is presented. The suggested method uses MPEG 1 Layer 3 compression to determine where and how the embedded mark must be introduced, combined with an error correcting code and a majority voting scheme. The scheme is shown to achieve high robustness against malicious attacks while maintaining a reasonable imperceptibility. The mark is embedded by modifying the magnitude of the spectrum at certain frequencies which have been chosen according to their relevance. The results show that the suggested watermarking scheme is robust against the attacks of the audio StirMark benchmark and compression attacks using the Sound Quality Assessment Material as the experimental corpus set.
