<div>Hi there, I was studying the window functions for FFT, so I was trying to build into vanilla pacthes the window functions that come on Pd-Extended [windowing] package. I got to do them all, but kaiser~ and gaussian~</div>
<div><br></div><div>Do any of you feel capable to perform this ver nerdy taks?</div><div><br></div><div>Well, anyway, here are some inconsistencies/mistakes I found ont the description of the formulas that are present in the help of those external objetcts:</div>
<div><br></div><div>- blackman~ instead of 0.8 it should be 0.08</div><div><br></div><div>- welch formula: 1-abs(x) - not sure, but doesn't seem to be right or clear. I used this one: <a href="http://paulbourke.net/miscellaneous/windows/">http://paulbourke.net/miscellaneous/windows/</a></div>
<div><br></div><div>- barlett~: 1-x^2 doesn't seem to be right or clear either, I used this one: <a href="http://mathworld.wolfram.com/ApodizationFunction.html">http://mathworld.wolfram.com/ApodizationFunction.html</a></div>
<div><br></div><div>- connes~: cos(pi*x/2) - it's the same as cosine~ so it can't be right, I used the above link again.</div><div><br></div><div>Cheers</div><div>Alex</div><div><br></div><div><br></div><div><br></div>
