g729编码解码器，挺好的用于学习音频编解码入门(g729 codec)

说明：  用matlab实现压缩感知，基追踪（BP）算法，将最小L0问题转化为最小L1问题。(Use matlab to implement compressed sensing, base tracking (BP) algorithm, convert the minimum L0 problem into the minimum L1 problem.)

很经典的MELP的MATLAB算法仿真。从一个外国网站上下载，很棒(MELP is the classic algorithm of the MATLAB simulation. From a foreign website, great)

说明：  光谱预处理auto 光谱预处理center(Spectral pretreatment)

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)

说明：  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.)

说明：  MeLPe Codec 1200 bps

g729a音频编码库,编码pcm为g729a,可压缩16倍(G729a library audio coding, coding PCM for g729a, compressible 16 times)

说明：  MT4编程参考，详细介绍MQ4语言的语法和使用方法，非常实用，在网上很难找到。(MT4 programming reference, detailing MQ4 language syntax and use, very practical, it is difficult to find online.)
