WebZero padding allows one to use a longer FFT, which will produce a longer FFT result vector. A longer FFT result has more frequency bins that are more closely spaced in frequency. But they will be essentially providing the same result as a high quality Sinc interpolation of a shorter non-zero-padded FFT of the original data. The FFT is used in digital recording, sampling, additive synthesis and pitch correction software. The FFT's importance derives from the fact that it has made working in the frequency domain equally computationally feasible as working in the temporal or spatial domain. Some of the important applications of the FFT … See more A fast Fourier transform (FFT) is an algorithm that computes the discrete Fourier transform (DFT) of a sequence, or its inverse (IDFT). Fourier analysis converts a signal from its original domain (often time or space) to a … See more Cooley–Tukey algorithm By far the most commonly used FFT is the Cooley–Tukey algorithm. This is a divide-and-conquer algorithm that recursively breaks down a DFT of any composite size $${\textstyle N=N_{1}N_{2}}$$ into many smaller DFTs of sizes See more Bounds on complexity and operation counts A fundamental question of longstanding theoretical interest … See more The development of fast algorithms for DFT can be traced to Carl Friedrich Gauss's unpublished work in 1805 when he needed it to interpolate the orbit of asteroids See more Let $${\displaystyle x_{0}}$$, …, $${\displaystyle x_{N-1}}$$ be complex numbers.
