Abstract(in English) The clipping attack is a serious problem in audio watermarking. When the watermarked audio suffer a clipping attack, it destroy a synchronization between the encoder and decoder then it is difficult to recover the right watermark. In this paper, we analyze the influence of clipping attack on watermark with the purpose to obtain reliableinformation and guarantee a better watermark decoding. Using that information, we propose a fast algorithm with clipping tolerance using codes with cyclic characteristics.
