深刻理解DFT和基2-FFT的算法原理、编程思想，掌握C程序设计的基本技术。-A deep understanding of DFT and the 2-FFT-based algorithm, programming ideas, grasp the basic C programming techniques.

在C++环境下的离散傅里叶变化，我自己运行过的，是可以运行的-In C++, the discrete Fourier changes, I have been running to be able to run

Goertzel DFT implementation in C#. This is Goertzel s style of calculating Discrete Fourier Transform, is a windowed transform similar to STFT. This implementation will need some small modification for your use, but I post because it is rare in

该段代码是基于C语言的实现FFT算法的一个程序，这个程序能够实现由DFT向FFT改进后实现了加速的功能！-this code is the design of fft base on the C language
