FFT (or Fast Fourier Transform) is a tool used to represent graphically the spectral constituents of a sound. The sound is mathematically analysed and is reduced to its various overtone components in their dynamic evolution over time. The graphic representation of an FFT usually plots the amplitudes of the frequency bands over time, offering a highly readable and visual representation of the sound being examined.
