Chapter 10 discusses various practical STFT applications such as fundamental frequency measurement, cross-synthesis, spectral envelope extraction, sinusoidal modeling, time-scale modification (frequency scaling), and audio FFT filter banks. It is a good idea to scan Chapter 10 now to get a feel for practical techniques in common use.
