FFT (Fast Fourier Transform) – Definition & Detailed Explanation – Sound Engineering Glossary
What is FFT (Fast Fourier Transform)? FFT, or Fast Fourier Transform, is an algorithm used to compute the Discrete Fourier Transform (DFT) of a sequence, which is a mathematical technique that transforms a signal from its original domain (usually time or space) to a representation in the frequency domain. The FFT algorithm efficiently computes the … Read more
