语音参数提取：短时过零率、短时能量、短时平均幅度、自相关序列、傅里叶分析-Speech parameters extraction: short-time zero-crossing rate, short-time energy, short-term average autocorrelation sequence, Fourier analysis

短时分数阶傅里叶变换,用于多分量线性调频信号的识别过程(Short Time Fractional Fourier Transform)

matlab实现短时傅里叶变换的程序源码，自带例子，十分简单易懂，可以做时频谱分析。(Matlab short-time Fourier transform program source code, with examples, very simple to understand, can do time-frequency spectrum analysis.)
