[Special Effects] FFT DL : 0: 1. 运行myfft.exe 把音频数据经过fft后存放在data.txt文件中 2. 再运行HUITU.exe把data.txt中的数据一帧一帧的画到屏幕上，形成动态效果 3. 运行soundee.exe 是还原声音注:其中myfft.c是fft的C语言代码，用VC实现的；HUITU.C是绘图代码，用TC实现的；soundee.c是还原声音代码，用VC实现的。 -1. Myfft.exe run the audio data stored in the post-fft file data.txt 2. HUITU.exe to re-run the data in the data.txt a picture to a screen to form a dynamic effect 3. Soundee.exe is running to restore the sound Note: myfft.c which is the fft of the C language code, using VC achieved HUITU.C is drawing code, using TC achieved soundee.c code to restore the sound, achieved using VC.
