fftin~ sinus window

Hello !

Is there the possibility to have a sinusoid window with fftin~ ? I
only see square, triangle, hanning, hamming and blackman. Sinus is
widely used.

A good thing with fftin~ would be the possibility to set a window
buffer~ name as argument too…

Actually this is already possible. Just set the name of a buffer~
instead of the predefined windows type.

Yes, indeed. Thank you.
I remember it now you remind me. ;) You can change the help patch.

See you at Selecta machine !

The widely used sinus is called hanning window, sometimes called raised
cosine…

I don’t know of other widely used sinusoid windows in fft…

hello Stephan ! :)

< yes, indeed, you are totally right. But I my special case, I wanna
a half sine wave window, easier for me with energy calculations; this
is what I fast called sinus. Window choice is like red wine.

But a sine window is like a Beaujolais nouveau… ;-)
