用于对信号的HHT分析，可得到IMF、功率谱、边际谱等图(HHT for signal analysis, obtained IMF, power spectrum, marginal spectrum, etc. Figure)

features to voice and un voice classification , pitch determination whith AMDF and other features like Spectral Centroid and Entropy of the energy

讲UPF的一个PPT,只对一篇经典文章的总结,我觉得很好,比看文章更能抓住重点.(UPF speaking of a PPT, is only a summary of the classic article, I feel good, better than to see the article focused.)

matlab工具箱，matlab的参考教程包括所有matlab函数总汇，(matlab toolbox, matlab reference tutorial matlab functions, including all the pool of)

K分布仿真的一部分，一部分是斑纹分量 还有是结构分量 两者点乘得到K分布序列 (K distribution part of the simulation, in part, there is a structural component markings component of both the dot distribution sequence obtained K)

实现物种功能的语音处理：倒谱、时域、频谱、语谱图以及功率谱，并加有详尽的注释。另外还可以保存图像，一倍后来研究！matlab ＧＵＩ编程(Voice processing functions to achieve species: cepstrum, time domain, frequency spectrum, spectrogram and power spectrum, and add detailed comments. It also can save the image, doubled and later research!)

spectrum_sub是谱减函数，使用谱减的方法达到降噪的目的，对于一般的平稳信号效果特别好。(Spectrum_sub is spectral subtraction function, using the spectral subtraction method to achieve the purpose of noise reduction, for general stationary signal effect is very good.)

极好的matlab入门教程， 自己用的时候感觉很好，推荐！(Excellent introductory tutorial matlab, I have used, recommended!)
