Hi!
I believe you would a) Just record her twice and she'll never EXACTLY do the
same, so result achieved. You take some shoRT stereo-delay or you take one
recording, double it and nudge it, whatever that is. There a doubler in the
TAP plugin suite. And in ecasound you could use -etd (stereo delay). That's
all I know, which may work. Probably there's more and more sophisticated.
Hope that helps!
Kindest regards
Julien
