matlab实现的阶次分析算法，用于变转速机械故障特征提取，可运行，包含寻找脉冲时刻，等角度时刻，数字跟踪滤波，样条差值等步骤(The order analysis algorithm realized by Matlab is used to extract the fault features of variable speed machinery. It can be operated, including the steps of finding impulse moment, equal angle moment, digital tracking filtering, spline difference and so on.)

这是G.723和G.729的音频编解码的源代码，当在网络带宽不够的时候可考虑采用该语音编码方式。(This is the G.723 and G.729 audio codec source code, When the network bandwidth may be insufficient time to consider the use of the voice coding.)

Voice decoder Standard interantional

MMSE语音降噪算法，使用维纳滤波器的方法，运算量适中，能实时处理(MMSE weiner noise reduction)

基于melp算法的语言编码传输，用于语言压缩传输(Speech coding transmission based on MELP algorithm)

A率13折线的编译码实现 1、了解PCM及13折线A率编码及译码的原理； 2、随机给出一个语音信号，并用A率13折线PCM对其编码； 3、将编码后的信号经过加性高斯白噪声信道，并在接收端对其进行译码； 4、分别画出原始语音信号、PCM编码信号以及译码后信号的波形。 (A rate of 13 polyline encoding and decoding implementation 1, to understand the principles of PCM and the broken line 13 A rate of encoding and decoding Two were given a voice signal, and PCM encode A rate of 13 polylines 3, the encoded signal through an additive white Gaussian noise channel, and the receiver decodes 4, respectively, to draw the waveform of the original speech signal, the PCM encoded signal and decoding signals.)

FS1016源代码，用MATLAB语言编写得，好东西啊(FS1016 source code, using MATLAB been prepared, good things ah)

g729编码解码器，挺好的用于学习音频编解码入门(g729 codec)

说明：  g729a 语音编码,再linux c 环境下实现,有非常的好的移植性,通话质量好(g729a voice coding, and c linux environment, and it is very good transplant, good call quality)

实现基于C语言的G.729A算法的编码程序，可调试成功，其中添加了部分对于程序的理解及注释，方便阅读(Achieve coding procedures G.729A algorithm C language can be successful commissioning, which adds some understanding for the program and notes for easy reading)
