This video covers the benefits of Time-Frequency domain representation, the fundamentals of the Short-Time Fourier Transform (STFT) and the influence of the window function on the spectrogram. The explanation part on the FFT uses a modified version of 3Blue1Brown's video on "But what is the Fourier Transform? A visual introduction." [3] Sound by SoundsExciting [4].
