Two methods are provided for hassle-free Short-Time Fourier Transform (STFT) computation.

In Method I, the DFT of all signal frames is computed via a single matrix product and serves those who want to gain more insight on the DFT computation mechanism by vectorizing the frame transformation process.

In Method II, the DFT of each signal frame is computed via a frame-by-frame FFT by use of the matlab's buit-in function fft.m.

I also provide 2 demos, one for each method, illustrating their practical use.
Also, some audio files are included for sake of experimentation.
