因子分析。该程序已经调试好了 直接可以使用(Factor analysis. The program has a good debugging can be used directly)

This program apply downsampling on a speech file.

SVD滤波方法，主要是通过对信号进行奇异值分解，将噪声部分的值归零，再进行信号的重构，顺利地进行滤波。(SVD filtering method, mainly through singular value decomposition of the signal, the noise part of the value of zero, and then signal reconstruction, smoothly filtering.)

It randomizes the order of vectors within the matrices

1. 对给定语料估计其基音周期。 要求用MATLAB语言实现有关基音检测算法，并给出检测结果。2. 实验语料：aoYiSheng.raw 发音：“茅以升”；时长0.9s；采样率：8kHz；量化精度为16bits/sample；数据格式 LSB,MSB分析帧长:20ms(160样点)总帧数：45(1. Corpus right to set its estimated Pitch. Asked to use MATLAB the pitch detection algorithm, and gives results. 2. Experimental corpus : aoYiSheng.raw pronunciation : "Mao Yisheng"; Time-0.9s; Sampling rate : gunfire; 16bits/sample accuracy of quantification; LSB data format, MSB analysis frame size : 20ms (160 samples) total frame count : 45)

同一信号乘以不同增益后的最佳基系数的能量累积曲线(After the same signal is multiplied by the different gain the best coefficient of energy accumulation curve)

盲源分离；求峭度；可以把混合信号分离出来，并且可以比较前后分离信号的峭度(Blind source separation seek kurtosis can separate the mixed signal, and the signal can be compared before and after the separation of kurtosis)

说明：  能够对于奇异值的计算matlab代码，它可以加强攻击性的抵抗能力。(Singular value can be calculated for the matlab code, which can enhance resistance to attack.)
