一种基于DCT变换的音频数字水印，将MP3音乐声音文件转化为WAV声音文件，将水印信息嵌入到WAV声音文件，再将WAV声音文件转化为MP3音乐声音文件。 -DCT-based audio digital watermark, the MP3 music sound files into WAV sound files, the watermark information embedded into the WAV sound files, and then WAV sound files int

编程获取wave的文件头信息并通过界面显示出来-Programming for wave file header information is displayed through the interface

基于wav文件的LSB位信息隐藏算法，在听觉上区分，两者靠人耳听不出任何差别-Based on LSB wav files a hiding information algorithm, in hearing distinguish, both by the human ear to listen to any difference

WAV音频的LSB信息隐藏，隐藏文件为二值图像，Matlab编程-WAV audio LSB information hiding, hidden files as binary image, Matlab programming
