Computation of the time-frequency response over a short window of data and displaying the spectra as frequency 'slices'. Commonly applied in seismic interpretation, seismic geomorphology and quantitative seismic interpretation.

A variety of time-frequency decomposition methods can be used for the computation, for example:
