Wouldn't it be possible to rid yourself of the "glitch" problem by crossfading
the section you are working with?  They do this to get "clickless" loops in
samplers, and it seems the technique might work here.  Just make a copy of the
section, reverse it, ramp the volume up like this:  "/"

Then, ramp the volume down of the original section like this: "\"

And mix the two together.  Then beat until smooth (just kidding).  Then
do your fft on that modified section.
