Shannon) Distribution: na Organization: Academic Computing Center, University of Va. Lines: 13 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? - Paul Shannon - pts@virginia.edu
