G711A/U的编解码，测试可用，不过噪声比较大

一个cd播放程序，用vb编成,支持多光驱。能自动搜索，自动播放。-a cd player with vb makeup and support the drive. Can automatically search, automatic broadcast.

由VC实现的一个简易的CD机，很简单，是VC初学者练习的好实例！-Simply CD Player Written by VC++.It is a very good example for beginner!

sndpeek is just what it sounds (and looks) like: real-time 3D animated display/playback can use mic-input or wav/aiff/snd/raw/mat file (with playback) time-domain waveform FFT magnitude spectrum 3D waterfall plot lissajous! (interchannel correlation) rotatable and scalable display freeze frame! (for didactic purposes) real-time spectral feature extraction (centroid, rms, flux, rolloff) available on MacOS X, Linux, and Windows under GPL part of the sndtools distribution. -sndpeek is just what it sounds (and looks) like: real-time 3D animated display/playback can use mic-input or wav/aiff/snd/raw/mat file (with playback) time-domain waveform FFT magnitude spectrum 3D waterfall plot lissajous!

一个比较小巧的媒体播放器，自己可以在此基础上添加需要的功能-a more compact media player, and they would like to add on the basis of the functional needs

在信号处理中，通常需要把采集信号的实时波形显示出来。 如果直接在屏幕上动态绘图的话，会出现闪烁现象，为了克服这个问题，本文采用的就是先在内存绘图，然后再拷贝到屏幕，从而实现动态绘图而不闪烁。-In signal processing, usually need to collect real-time waveform signal is displayed. If the direct dynamic graphics on the screen, then there will be blinking phenomenon, in order to overcome this problem, this paper is the first graphics memory, and then copied to the screen in order to achieve dynamic graphics without blinking.

制作能播放MIDI，WAV和AVI文件的播放器-can produce broadcast MIDI, WAV, and AVI file player

DirectShow音频采集：采用DirectShow库进行音频采集/录制，很好的代码，可以很方便的当成一个单独模块移植 到其他项目中，拿出来与大家分享。

这是一个简单的代码，用于接收来自麦克风的输入，并将输出输出到扬声器上。
