A number of people pitch in here and there.\n\nThanks -- actually we don't need to anymore as it turns out its behavior is\nas described (fft computation on real input uses conjugate symmetry for\nspeed already). The gains seen here come from a reduced number of\nmultiplies with the window function because rfft only returns positive\nfrequencies. The PR title should probably be updated to reflect that, as\nright now people could reasonably assume rfft makes gains over fft for\nincorrect reasons, as most (all?) of us initially did.\n"}}
