说明：  该程序主要也是针对滤波器设计的，实现了对一个语音信号的滤波处理(The program is largely designed for the filter, the realization of a voice signal filtering)

这是本人原创的数学建模论文，希望对参加数学建模建模的同学有帮助(This is the mathematical modeling of my original thesis, I hope to help students to participate in the mathematical modeling modeling)

此文件实现了让语音信号通过低通，高通，带通滤波器使其变声，并且在GUI界面上绘出了个滤波器的频率响应和语音信号的频谱。(This file allows to achieve a voice signal through a low pass, high pass, band pass filter to make it change the sound, and plotted on a GUI interface and voice signal spectrum frequency response of a filter.)
