How do i make a Dark and Evil vocie

[Xanthos]

(For Sony Vegas) First, record what you want to say and then put it in the editor. Then, right click the track and click "Apply Non-Real-Time Event FX" and it will give you a list of effects. If you want a very low pitched voice, find and double click "Pitch Shift" and then press OK. Check "Preserve duration" and lower the Semitones slide to somewhere around -4 and press OK again. If you are still confused then just look up a tutorial on Youtube.

+1 rep for that!
I couldn't find out how to do that.
