These have caught my interest so far:
Reapers Reapitch: Can use Elastique2, Elastique 1, Dirac and Soundtouch algorithms <-Cheap alternative
Cubase Studio 4: Mpex3 algorithm <-Cheap update from my SL3
RBC Voice Tweaker 4.2: Last time I heard the voice tweaker it sounded crap, but things might have changed with newer versions
Soundforge 9: Dirac algorithm <-more expensive, but maybe a good investment since I dont have a payware audio editor
Maybe there are some alternatives I´ve missed? Melodyne isnt what I`m after, seems that is more a pitch correction tool for vocals not dialog/sfx.
Formant adjusting is important.
Any tips are welcome!
Edit: too bad Soundhack is Mac only. It´s freeware and I read some cool things about it. http://www.soundhack.com/freeware.php
