遗传算法（Genetic Algorithm）是模拟达尔文生物进化论的自然选择和遗传学机理的生物进化过程的计算模型，是一种通过模拟自然进化过程搜索最优解的方法。(Genetic Algorithm (Genetic Algorithm) is a simulation of natural selection and genetics of Darwinian biological evolution computational models of biological evolution, the process is a way to search the optimal solution by simulating the natural evolution.)

对原始语音进行上采样和下采样，分析对比他们的时域图和频谱图。最后对比原始语音、75HZ激励、150HZ激励以及噪声激励下的效果(SOME SIMPLE MANIPULATIONS OF SOUND USING DIGITAL SIGNAL PROCESSING The original sound and its spectrogram Downsampling the waveform downsampling Upsampling the waveform Linear filtering the waveform Original speech The source-filter model of speech Speech with 75-Hz excitation Speech with 150-Hz excitation Speech with noise excitation)

主成分分析法源码，可用于提取主成分，识别率百分之九十(the PCA code)

这是一个很基本的pso算法的matlab的源码。比较的简单，但是可以再这个基础上修改的(This is a very basic PSO algorithm matlab source code. Comparison of the simple, but can be modified based on this)

该程序是方向滤波器工具包，其中有很多现成的滤波器，及上下采样程序。可直接调用。(The program is the direction filter kit, there are many ready-made filter, and down sampling procedure. Can be called directly.)
