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~
Do any of you feel capable to perform this ver nerdy taks? 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: - blackman~ instead of 0.8 it should be 0.08 - welch formula: 1-abs(x) - not sure, but doesn't seem to be right or clear. I used this one: http://paulbourke.net/miscellaneous/windows/ - barlett~: 1-x^2 doesn't seem to be right or clear either, I used this one: http://mathworld.wolfram.com/ApodizationFunction.html - connes~: cos(pi*x/2) - it's the same as cosine~ so it can't be right, I used the above link again. Cheers Alex
