读取wav文件 画图显示波形，低层打开wav读取数据，然后绘制波形图。-Wav file to read drawing waveform, the lower open wav read the data, and then draw the waveform.

将读取WAVE波形，读取wav文件格式 c++ wav文件头-Read WAVE waveform, read wav file format c++ wav file header

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
