一款简单的VC++6.0编程MP3音乐播放器，附带源码已经工程文件。(A simple VC++6.0 programming an MP3 music player, already works with source files.)

Savitzky-Golay 滤波算法的资源汇总，原理阐述(Savitzky-Golay filtering algorithm resource summary, the principle expounded)

vc++平台下的jpeg解码程序，简单易懂。(decode jpeg on vc++ platform，easy to understand)

vc++写的网络录音机程序，录音是参照vckbase的录音api代码,结合了一小段socket(TCP)就可以用来单方说话录音了,程序分两部分一部分是(录音机+网络发送代码),一部分是(接收数据+播放波形音乐代码),由于程序只是为了自己用,很多地方没有注意错误的识别,结构也比较乱,本程序当初最头疼的就是控制损耗内存,结果用了双缓存来存储波形数据来交替的存储/清除.(vc++ program to write the network recorder, audio recording reference vckbase api code, combined with a short socket (TCP) can be Speak to unilateral recordings, and part of the program in two parts (recorder+ network to send the code), part (Receive Data+ play wave Music code form), because the program only for their own use, many places do not pay attention to the wrong identification, the structure is chaotic, the program had The most troublesome is the loss of memory control, the results with the double buffer to store the waveform data to alternate storage/removal.)

基于短时能量和短时过零率来实现语音端点检测。也称为双门限比较法，是一种传统的 语音端点检测方法。现在已经有研究人员提出若干其他更加高效和有效的检测方法，但 是这个方法不失为一种最简单的方法，可以通过程序来获得语音端点检测的感性认识和 体会。内的程序读取WAV文件，程序附有详细的使用说明和注释，以及若干测试用的语音文件。(Based on the short-term and short-term energy to achieve zero rate of voice activity detection. Also known as dual-threshold comparison method, is a traditional method of voice activity detection. Researchers now have made a number of other more efficient and effective detection methods, but this method may be one of the most simple way to get through the process of voice activity detection and the experience of perceptual knowledge. Procedures within the WAV file to read, procedures with detailed instructions and notes, as well as the voice of a number of test documents.)

深入浅出DirectShow Filter 学习资料，很实用。(Layman DirectShow Filter learning materials, it is practical.)

VC 编写的播放器，功能已经很完善。适合初学者参考(VC prepared player, features have been very perfect. Suitable reference for beginners)

本程序为多媒体通信的server端的源码（ VC++ 6.0 以上版本）(the procedures for multimedia communications server side of the source (VC version 6.0 and above))
