代码说明：

对非平稳信号进行分段、截取，再对处理过后的短时信号做短时傅里叶变换，分析其频谱特性，并找到各个时间节点的频率特性，以便分析不同事件段内的声音特征。(The nonstationary signals are segmented, and then the interception, the short-time signal after processing the short-time Fourier transform, the analysis of the spectrum characteristics and frequency characteristics and find the different time node, in order to analyze the acoustic characteristics of different event period.)

DFT
信号与系统试验报告离散傅立叶变换（DFT）和频谱分析一、实验内容 1、实验题目（1）编写DFT、IDFT程序，并验证其正确性（提示：可利用冲激函数进行验证）。（2）计算信号f(t)=e-at2sin(2∏ft)的离散傅立叶变换（DFT），求其振幅谱，相位谱、振幅最大值对应的频谱（检测主频）以及对发f(t)进行DFT变换的结果实现IDFT变换，并画出图形。参数选择如下：频率f =30HZ，a=f 2㏑(M),M=2.5 2、通过实验理解信号振幅谱、相位谱的物理意义，掌握DFT、IDFT算法的实现方法。()
