提出了一种在音频信号中嵌入二值标识的盲数字音频水印方法。该方法使用二维二进小波变换（DYWT）。为了应用二维DYWT，我们通过将原始音频信号分成几个部分并将这些部分按行排列来从音频信号构建图像。由于DYWT具有冗余表示，水印必须携带的信息量高于基于离散小波变换（DWT）的方法，这是非常流行的。我们详细描述了我们的嵌入和提取过程，并显示实验结果表明，我们的方法提供了水印信号，具有更好的质量和鲁棒性的攻击，如剪切和一些音频压缩。
We propose a blind digital audio watermarking method for embedding a binary logo in an audio signal. This method uses the two-dimensional Dyadic Wavelet Transform (DYWT). To apply the two-dimensional DYWT, we construct an image from an audio signal by dividing the original audio signal into several parts and arranging these parts in rows. Since the DYWT has a redundant representation, the amount of information that the watermark must carry is higher than in discrete-wavelet-transform -- based (DWT-based) methods, which are very popular. We describe our embedding and extracting procedures in detail and show experimental results demonstrating that our method gives watermarked signals that have better quality and that are robust against attacks such as clipping and some audio compressions.
