Fast Fourier Transformation FFT - Basics - NTi Audio

    https://www.nti-audio.com/en/support/know-how/fast-fourier-transform-fft
    The "Fast Fourier Transform" (FFT) is an important measurement method in the science of audio and acoustics measurement. It converts a signal into individual spectral components and thereby provides frequency information about the signal. FFTs are used for fault analysis, quality control, and condition monitoring of machines or systems.
