说明：  这个程序生成正交频分复用信号和它的频谱,很经典，尤其对于初学者很有帮助(This procedure generated orthogonal frequency division multiplexing signal and its spectrum, it is classic, especially useful for beginners)

C#写的屏幕实时监控软件的完整源代码，屏幕图像实时采集调用dfmirage。可到http://www.pudn.com/downloads611/sourcecode/multimedia/vfw/detail2489590.html中下载(Screen real-time monitoring software written in C# complete source code, the screen image real-time collection called dfmirage. To the http://www.pudn.com/downloads611/sourcecode/multimedia/vfw/detail2489590.html Download)

演示采样定理，时域采样，频谱周期延拓同时演示采样频率小于2*fc时，产生的混叠效应。可作函数应用(Demonstration sampling theorem, time-domain sampling, the spectrum at the same time cycle extension demonstration sampling frequency is less than 2* fc, the resulting aliasing effect. Function can be used for applications)

基于DirectSound的声音播放器。本实例将介绍使用DirecSound技术编写的声音播放器，DirecSound编程技术在多媒体编程中需要经常用到。(DirectSound-based audio player. This example describes the preparation technique using DirecSound sound player, DirecSound programming technique often used in multimedia programming needs.)

有四套录音的demo，都实现了录音功能，播放录音的功能，还是很不错的(There are four sets of recording demo, realize the recording function, play the recording function, or very good)

一个基于ffmpeg的视频播放器示例，支持各种视频格式和编解码器(ffmpeg player)

说明：  newmark法计算响应的收敛问题 程序是王勖成书中的程序 质量、刚度矩阵的存储形式已经由原来的半带宽存储改为全矩阵存储的形式，特殊需要 质量、刚度矩阵应该没有问题，因为计算出来的固有频率是正确的(Newmark method in response to the question of the convergence process is Wang Xu procedures into the quality of the book, stiffness matrix from the original storage format has been changed to the semi-bandwidth storage full matrix storage form of the special needs of quality, stiffness matrix should not be a problem, as calculated natural frequency is correct)

能实现视频帧格式的选择，前一帧的播放，整个视频的文件播放(Can realize the video frame format of choice, before playing a frame, the video file playback )

web完美内嵌vlc播放器源代码！不需修改任何东东，个个按钮均采用js制作！你可以直接把文件名换成html格式，直接运行即可！(perfect web embedded player vlc source code! Do not modify any Dongdong, each button are produced js! You can directly to the file name into html format, can be directly run!)

简单的视频播放器,对视频开发不是很明白的人很有帮助(simple videoplayer，very helpful for those who are learning video developing)
