利用AD0809将音频信号数字化,存入RAM-AD0809 will use the digital audio signal into the RAM

又一个DirectSound实现混音的例子- A DirectSound realization mixes the sound the example

语音信号利用LBG训练方法，实现在特征AR域的聚类，制作码书。码书大小，维数，失真限可调。可以用较小的误差重建原始信号。

LPC 线性预测编码 语音经典的编码方式，能够预测激励信号，同时去除语音之间的相关性，进行编码，达到最小的信息量

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!

linux下的简单音频播放软件，支持wav等基本格式，代码很小，适合移植到嵌入式设备使用-linux under the simple audio player software, and other basic support wav format, the code is very small, suitable for transplant to the use of embedded devices

音频采集进行波谱分析并输出的小程序，比较简单，功能作为试验用-Collected for analysis of the audio spectrum and the output of small procedures, relatively simple, function as a pilot with

对AAC的音频文件进行分析并输出各种音频格式的源代码，十分难得！-Of AAC audio files to analyze and export a variety of audio formats, source code, is very rare!
