In the overlap-add formulation of Chapter 8, we used a
hopping window to extract time-limited signals to which we
applied the DFT. Assuming for the moment that the hop size
(the ``sliding DFT''), we have

This is the usual definition of the Short-Time Fourier Transform
(STFT) (§7.1). In this chapter, we will look at the STFT from
two different points of view: the OverLap-Add (OLA) and
Filter-Bank Summation (FBS) points of view. We will show that
one is the Fourier dual of the other [9]. Next
we will explore some implications of the filter-bank point of view and
obtain some useful insights. Finally, some applications are
considered.
