用matlab实现音频处理功能，两个音频文件模和相位互换，比较互换之后的音频文件的效果-using Matlab achieve audio processing functions, two audio files modulus and phase swap Comparing the exchange of audio files after the results

一个音频水印嵌入演示界面，嵌入容量较大。可供参考-An audio watermark embedding demo interface, embedded in a larger capacity. Reference

利用matlab自带的小波函数对音频进行分解然后嵌入经降维之后的图像水印并提取-Matlab comes with wavelet function to decompose the audio and image watermark embedded by the dimensionality reduction and extract
