Is there a common name for this window function?
I made it to replace a Hann window used in loading an FFT.
It is basically a wide lobe cosine tapered window, or negative Blackman window. Is there a better more common name?
$y = 0.5 * (1.25 - \cos(\pi * 2 * {x \over N}) - (0.25 * \cos(\pi * 4 * {x \over N})))$
$N$ is the total number of samples.
