Abstract In this paper, a blind audio watermarking scheme based on spreadspectrum technology is proposed. The blind detection is implemented using linear prediction coding as a whitening procedure. By a series of techniques, including sophisticated subband selection and PN shaping, the robustness and the imperceptibility of proposed algorithm are comparable to those of the nonblind algorithms which are demonstrated in the experiments. Also, the watermark capacity of proposed algorithm is larger than that of other blind ones.
