We have a psychoacoustic experiment in which we wish to play short segments of 
recorded speech, at varying pitches.  For instance, we record a deep male voice
saying a word, and we want to be able to play that word back at a high pitch.

The pitch-changing tool in MacRecorder (from Farrallon Computing)  is unable
to preserve the tempo of the original sound: shifting pitch upwards always 
shortens the duration of the sound, and increases the tempo.

Does anyone know of Mac software that allows us to change pitch *without* 
changing tempo and duration?
