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.)

MIDI转换软件 用于MP3产生midi(MIDI to MP3 conversion software generate midi)

Visual C++音频视频处理技术及工程实践书的原代码，非常好呀(Visual C++ audio and video processing technology and engineering practice of the book source code, excellent)

多媒体播放程序，可以播放图片，影片，网页。(Multimedia player, you can play pictures, videos, web pages.)

DirectSound加VC6.0实现播放Wav文件时添加各种音响效果(DirectSound plus VC6.0 for playing Wav file to add various sound effects)

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.)

说明：  本源程序代码示例了图像的变化,可以让读者对图像的编程有所了解!(The source code examples of the image changes, allowing readers to understand the programming image!)

做一频谱分析处理，为滤波提供频率(Spectrum analyzer to do one deal, in order to provide frequency filtering)
