Short-Time Fourier Transform is an analysis tool that repeatedly applies the Discrete Fourier Transform (DFT or FFT) to short segments of a longer signal, while sliding the window that selects the segment of the longer signal that the STFT operates on. The STFT is a function of two independent variables, frequency in the DFT and the time of the center of the sliding window.

output shape of STFT
this is the exact word of this paper wich applied STFT on 3 channel of eeg signal :
Short time Fourier transform (STFT) was applied on the
time series for each 2 s long trial. … STFT was performed with
window size equal to 64 and time lapses equal to 14. …
