"WebAs we have observed in this lecture, the STFT enables us to trade-o↵time and frequency resolution as a way to analyze our signals. This trade-o↵is controlled by the choice of STFT window (eg: broad vs narrow), and limited by the uncertainty principle (Eq. 16.2). The main limitation of the STFT is that it has a ﬁxed temporal resolution ... " - Stft allocate
