This character is a smaller role. She pops up once assisting dangerous associate of hers in observing some phenomena. This character voice is expected to on the lower end. Alto to low-mezzo soprano, in music terms. The character is always a little on edge, a little concerned about the space around her. As much as she would want to help in any scenario, she's in a position where she can't act on her moral compass. Software wise, use whatever will get you a good clean cut of the line. As long as it can make Wavs and mp4, I'm all for it.
