V8; pitch shift quality on a vocal is quite poor

Ok all. A quick example. Dry vocal. Original provided. Then a 2 semitone upwards pitch shift with formants preserved. I used Melodyne Studio, Soundforge Pro Elastique, Spectralayers 7 and 8 pro. As I keep saying, I don’t use Spectralayers for pitch shifting of vocals, but it would be nice to see higher quality if I ever needed to. Eddie
