提出了一种实时音频水印方案。音频信号修改的强度受到产生与原始信号感知相等的输出信号的必要性的限制。该方案采用盲检测方法。为了嵌入水印，在调制复叠变换（MCLT）域采用扩频算法。在这里，水印是使用私钥生成的，并根据人类听觉系统进行建模。对几种美白方法在受体侧进行了比较。该水印对D/A转换、滤波、加噪和高质量MPEG音频编码等常见攻击具有较强的鲁棒性
A real-time audio watermarking scheme is presented. The strength of audio signal modifications is limited by the necessity to produce an output signal that is perceptually equal to the original signal. The proposed scheme uses a blind detection approach. To embed the watermark a spread spectrum algorithm is used in the modulated complex lapped transform (MCLT) domain. Here the watermark is generated using a private key and modeling according to the human auditory system. Comparison of several whitening methods in the receptor side is carried out. The embedded watermark is robust to common attacks such like, D/A A/D conversion, filtering, noise addition and high quality MPEG audio coding
