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.

Advantage of STFT over wavelet transform
You might need something like an STFT stage, with really large step sizes (e.g. 1 second), and then run the transform on each (1-second) window. … This might be a related reference in that vein
