An audio watermarking algorithm with self-synchronization based on complex cepstrum transform is proposed, which divides the original audio signal into several segments. Synchronization code is embedded into audio with the watermarks. The watermarks can be extracted without the original digital audio signal. The embedded watermarks are imperceptible and robust to many common attacks, such as noise adding, re-sampling, low pass filtering, re-quantization,cropping and so on.%本文提出了一种基于倒谱变换的自同步数字音频水印算法.算法对音频载体分段后,将同步码嵌入到时域上,将水印信息嵌入到变换域上.水印的提取不需要原始音频信号,是一种盲水印算法.实验结果表明,嵌入后的水印不仅具有很好的不可感知性,而且对添加噪声、重新采样、低通滤波、重新量化和剪切攻击也具有很好的稳健性.
