Pitch Shifting

Reviews Home : Listen & Compare : Pitch Shifting

For this comparison we have taken an acapella and shifted it down by a Major 3rd and then up by a Major 3rd (-/+ 4 semitones). Vocals are notoriously difficult to pitch shift without radically changing the character of the voice (the "chipmunk effect"). To see the larger view of each plug-in, click on the thumbnail.
   
Audition Pitch Shifting
Audition provides both real-time and batch pitch shifting. This example was created using the batch function in Audtion 2.

 
GarageBand Pitch Shifting
GarageBand provides real-time pitch shifting. It also includes a Vocal Transformer plug-in which is used for this example.
   
 
Sonar Pitch Shifting
Sonar's Loop Construction view as used to create a clip for real-time pitch shifting for this example. We found it necessary to add several slicing markers to prevent echo on the upshift.
 
Melodyne Pitch Shifting
Melodyne is noted for vocal processing. For pitch shifting it attempts to maintain the original character of the voice by separating the formants prior to shifting.
   
 
Pro Tools Pitch Shifting
Pro Tools LE provides a batch pitch shifting algorithm which was used for this example.
 
FL Studio Pitch Shifting
FL Studio provides batch pitch shifting. This example was created using FL Studio 6.

   
 
Acid Pitch Shifting
Timestretching for this example is accomplished in real time using Acid Pro from a beatmapped file created from the original vocals.
