Description: Basically, this article describes one way to implement the 1D version of the FFT algorithm for an array of complex samples. The intention of this article is to show an efficient and fast FFT algorithm that can easily be modified according to the needs of the user. I ve studied the FFT algorithm when I was developing a software to make frequency analysis on a sample of captured sound.-Basically, this article describes one way to implement the 1D version of the FFT algorithm for an array of co mplex samples. The intention of this article is to show an efficient and fast FFT algorithm that can easily be modified according to the needs of the user. I ve studied the FFT algorithm when I wa s developing a software to make frequency Analytics sis on a sample of captured sound.
