What is practical use of FFT, any examples?

Here you find more about it.

What it 'sees' is interpreted as a sum of frequencies and with the fft you can get the single frequencies..

  • en.wikipedia.org
A fast Fourier transform (FFT) algorithm computes the discrete Fourier transform (DFT) of a sequence, or its inverse. Fourier analysis converts a signal from its original domain (often time or space) to a representation in the frequency domain and vice versa. An FFT rapidly computes such transformations by factorizing the DFT matrix into a...
