STFT, Kaiser Window, Beta=10, 90% Overlap

Because the Kaiser window transform does not have harmonic nulls that can be tuned to harmonics of the frame rate (§8.3.1), we obtain only approximate perfect reconstruction. However, the reconstruction error is entirely under our control through the choice of the Kaiser-window $ \beta $ parameter (determining its time-bandwidth product). This filter bank does not rely on aliasing cancellation (when side-lobes are negligible), so it is very robust to spectral modifications.
