说明：  用MATLAB语言编写的基2 DIT FFT子程序& 用简单的速度很低的方法计算DFT(using MATLAB prepared by the two-DIT FFT routines)

这是薛定宇的经典书籍：高等数学问题的MATLAB求解~非常有用，非常详细，欢迎大家下载~(This is of Xue Dingyu the classic books: MATLAB higher mathematics problem solving to be very useful, very detailed, welcome to download to)

耳蜗实质上相当于一个滤波器组，耳蜗的滤波作用是在对数频率尺度上进行的，在1000HZ下，人耳的感知能力与频率成线性关系；而在1000HZ以上，人耳的感知能力与频率不构成线性关系，而更偏向于对数关系，这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(Cochlear substantially equivalent to a filter set, cochlear filter is used on logarithm frequency scale, under the 1000 hz, the perception of the human ear and a linear relationship with frequency In more than 1000 hz, the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula )
