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 mike -- MP3 ENCODER mailing list ( http://geek.rcc.se/mp3encoder/ )
