- Perfect reconstruction
- Oversampled by 2 (less reliant on aliasing cancellation)
- Poor channel isolation (
dB)
- Not very robust to filter-bank modifications, but better
Reducing the hop size to half the window length greatly reduces the
amount of aliasing in the filter-bank output signals (§8.3.1).
Recall that this happens because the folding frequency due to
downsampling (by the hop size) doubles to coincide with the first
zero-crossing of the window transform.
