采用MATLAB编写fft算法，读取wav文件，显示语音信号波形频谱，并且与matlab自带的FFT算法比较，波形相同证明编写的算法正确。包括GUI设计的人机交互界面-FFT algorithm using MATLAB to read wav file, display the waveform of the speech signal spectrum, and the matlab algorithm with the FFT comparison, the same waveform t

对一个WAV格式的声音的音频进行分段的读取从而便于对大格式的音频分析。-The audio of a WAV format sound is segmented to facilitate the analysis of large format audio.
