Spectrograms can be used as a way of visualizing the change of a nonstationary signal’s frequency content over time. … WebAug 5, 2015 · For a proper choice of the analysis window, a short-time Fourier transform is known to be completely characterized by its zeros, which coincide with those of the associated spectrogram. A simplified representation of the time-frequency structure of a signal can therefore be given by the Delaunay triangulation attached to spectrogram zeros.

WebDec 21, 2024 · The help for spectrogram, for the "f" option, says "Cyclical frequencies, specified as a vector. f must have at least two elements, because otherwise the function interprets it as nfft. The units of f are specified by the sample rate, fs." I think this means f should be specified as frequencies normalized by fs. WebA spectrogram is a two-dimensional representation of the square of the STFT X(m,k) X ( m, k), and can give us important visual insight into which parts of a piece of audio sound like a buzz, a hum, a hiss, a click, or a pop, or if there are any gaps.
