COLA Examples
So far we've seen the following constant-overlap-add examples:
- Rectangular window at 0% overlap (hop size
= window size
)
- Bartlett window at 50% overlap (
) (Since normally
is odd, ``
'' means ``R=(M-1)/2,'' etc.)
- Hamming window at 50% overlap (
)
- Rectangular window at 50% overlap (
)
- Hamming window at 75% overlap (
% hop size)
- Any member of the Generalized Hamming family at 50% overlap
- Any member of the Blackman family at 2/3 overlap (1/3 hop size);
e.g., blackman(33,'periodic'),
- Any member of the
-term Blackman-Harris family with
.
- Any window with R=1 (``sliding FFT'')
