Hi All,
I've had a request from someone in our department
for suggestions for a pitch shifting algorithm that will be used to shift the
frequencies of phoneme pairs (e.g. ba-da) into the center range of rat hearing
(~8kHz) without affecting the temporal cues of the speech stimuli. I'm
unfamiliar with available software to do this (and pros and cons for specific
kinds). We do have some commercial software here such as Adobe Audition and
SoundForge that have pitch shifting algorithms as part of their software
package. We are hoping to limit artifact as much as possible. Would these be
appropriate algorithms to use? If not, why not and any suggestions as to which
software program would be more appropriate?
Thanks,
Ben Hornsby
