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.

The reason why small FFT produces more heat, is because the cache is being used a lot more, not because the workload is more. Do not rely on small FFT for stability. Small FFT is a way to check your CPU's maximum heat output, and basically … WebbThe fast Fourier transform (FFT) is a discrete Fourier transform algorithm which reduces the number of computations needed for N points from 2N^2 to 2NlgN, where lg is the base-2 logarithm. FFTs were first discussed by Cooley and Tukey (1965), although Gauss had actually described the critical factorization step as early as 1805 (Bergland 1969, Strang … crucial system advisor tool
