另一个不错的频谱分析程序源码，虽然没有第一个程序感觉好，但是简单明了，容易理解

程序运行就打开录音设备，同时输出其波形和经过FFT变化后的波形。-Program runs on the open recording equipment, while the output of its waveform and after changes in the waveform after FFT.

别人写的用于windows下语音采集的代码，并对语音数据进行傅里叶变换和波形显示，很有参考的价值，与大家分享了-For windows under voice acquisition code written by someone else, and voice data to the Fourier transform and waveform display of great reference value, and to share with you a
