Abstract
In this paper, an audio watermarking algorithm is proposed which can resistant to A/D and D/A attacks. In the proposed algorithm, the randomized watermark image is coded based on OFDM. Then orthogonal transformation is used to reduce the PARR of the coded signal. The obtained watermark sequence is embedded into the audio based on the energy ratio of the wavelet coefficients in each audio period. The experiment result shows that the algorithm has good robustness and the watermark has better imperceptibility.
