对音频信号进行几种滤波，有汉明窗，切比雪夫，巴特沃斯等。可以输出时域和频域的对比图。-Several of the audio signal filtering, there is Hamming window, Chebyshev, Butterworth and so on. Can output time domain and frequency domain comparison of Fig.

this program deals with simple speech processing like fft, use of hamming window, my durbin algorithm and likes. this program has gui too.

以MATLAB软件为工具，在GUI图形用户界面下针对不同特点的语音信号进行八种不同模式的滤波处理的语音信号处理系统，涉及基于巴特沃思滤波器的IIR滤波器和汉明窗设计的FIR滤波器，能够实现语音文件的打开及自定义路径的存储功能，同时可以实现语音信号加噪和音频倒放功能。-The source code, by means of MATLAB, under the Graphical User Interface, achieves a kind of speech signal processing
