  "field": "Oil and gas",
  "definition": "An abbreviation for fast Fourier transform, an efficient algorithm for computing the discrete Fourier transform (DFT) and its inverse, which converts a sequence of data from the time or spatial domain to the frequency or wavenumber domain. This algorithm significantly reduces the computational time compared to a direct DFT calculation. It is widely used in seismic data processing for spectral analysis, filtering, and migration.",
