I run Audacity on Mac OS X 10.5.
Scramby's VST effects come from the field of professional studio musicians. Scramby comes with a comprehensive collection of almost 40 ready-to-use voice effects and numerous background noises that can be supplemented with an unlimited number of sounds you import or create yourself. I wasnt trying to undermine that. Thanks for the input. It's just that i need a way to get close to the vader voice. I read it can be done with a vocoder, but I dont know where to get a free RTAS or VST vocoder for OSX, nor would I know how to use it very well, since i've never experimented with a vocoder.
I am looking for a way to take a voice recording as input, apply some distortion filter and save the result as MP3.Things I would like to achieve in examples:
- Cortana's voice over in the Halo 3 revelation trailer
- Soldier's voice via a WWII radio transmitter (with all the crackles and drop-outs)
Star Wars Characters Darth Vader
- Darth Vader's voice
- Sci-Fi sounding voice effects (The Borg, etc.)
There are many Windows apps to do this, but few Mac apps.
Although, I found Audio Hijack Pro, which I have not tested yet.

On Windows, there is:
MorphVOX
AV Voice Changer
Darth Vader Powers
Could I use Audacity to do this? Is it too low lever for this very narrow type of project?
