人耳听觉特性的描述，作音频开发的工程师一定要看一看。

做音视频产品的同志肯定碰到我一样的问题，HD Audio的MicroPhone声音大小调节棒变灰不可调节，我这个程序就是利用Mixer 来辨别是哪种Audio，并Enable它。-Audio and video products that make sure the comrades encountered the same problem I, HD Audio Microphone voice the size of the adjustment rod adjustment is not grayed out, I make use of this procedure is the Mixer to identify which type of Audio, and Enable it.

Produce and play a sound signal of 6 seconds f(t)=exp(t-6)sin(2π*Ft) with a sampling rate of 8000dots/s by using MATLAB, with the frequency F being 494, 440, 392, 440, 494 and 494 Hz in order. Each frequency should last for 1 second.

aac+的解码器，可以在windows下运行，用vc6直接编译。可以解码row,ADIF,ADTS的aac文件-aac decoder can operate in the windows with vc6 directly translated. It can decode row, ADIF, the ADTS aac documents

适合学习mci的初学者，可以播放wav和avi，界面为mfc,推荐-adapt to the new learner of mci , and it can play WAV and AVI format file , interface is MFC. it is commended!

PortAudio是一个跨平台的音频库，可以用来开发音频信号分析软件，压缩包里是我做的DELPHI下使用PortAudio动态库的实例。-PortAudio is a cross-platform audio library that can be used to develop the audio signal analysis software, compression bag that I do use PortAudio dynamic libraries DELPHI examples.

一个视频的纹理，可以学习相关的编程知识，最好有一些 DIRECTSHOW的基础-A video texture, can learn the relevant programming knowledge, the best basis for a number of DIRECTSHOW

调整音频采样率,一般可以将wav格式的各种采样率音频转换成8k采样的^_^-audio sampling rate adjustment, the general can be wav format of audio sampling rate conversion 8k sampling ^ _ ^
