To answer my own post,
        I grabbed Sprenger's smsPitchScale.cp from http://www.dspdimension.com/
and wrapped a bit of support code around it.  This program will change the
pitch of an audio file - this means you can play it back so that talking is
twice as fast but *at the same pitch*  i.e. the talkers don't end up like
chipmunks, they just sound like they're rushing.  (I also found it can be used
to convincingly change a speaker's gender).
        grab it at http://www.cryogen.com/mikecheng 

later
