有关数据库，我认为数据库很重要，要认真学，我上传的是我们老师给我们的东西，你们看看对你们有用吗？(The database, I think the database is very important to carefully study, I uploaded is our teacher gave us something, you look to you useful?)

一个基于JMF框架的，多媒体播放器，可以支持mid,wav.mp3等文件(a framework based on JMF, multimedia players will be able to support mid, and other documents wav.mp3)

基于VC++实现的傅里叶变换源码，效果不错。(Fourier Transform source based on VC++ achieve good results.)

枚举系统的录音设备，录制并保存为MP3文件(Enumeration system, recording equipment, recording and save it as MP3 files)

Visual C++ 音频视频处理技术及工程实践，陆锦正 周冬梅编著随书光盘，包括以Visual c++ 2005为开发平台的多个工程实例及源码 (Visual C++ audio and video processing technology and engineering practice, LU Jin ZHOU Dong-mei is compiled CDs with books, including Visual c++ 2005 as a development platform for various projects in the examples and source code)

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.)

测试DirectDraw的裁剪器(Clippers）的例子。(Test the DirectDraw clipper (Clippers) example.)

通过麦克风能够实现对语音的录制和播放，很不错的代码(audio can be achieved through a microphone for voice recording )

音视频捕捉和回放类，并包含调节向导示例，示例中展示如何使用该类，开放人员完全可以将这些类放入自己的工程使用。代码使用direct sound技术封装，包含文件录音，多文件混音播放，本地录音回放，音量调节等多个功能示例。(video&audio wizard demo)

归一化混音源码,要求为pcm帧,采样精度16bit，内有测试音频(Normalized mixing source, the requirement for PCM frame and sampling precision of 16 bits, with audio testn)
