### 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'')

*squared*, it functions as a Hann window for overlap-add purposes (a member of the Generalized Hamming family). As such, it can be used with 50% overlap. More generally,

*any positive COLA window can be split into an analysis and synthesis window pair by taking its square root.*
