Hi John, This is an audio editor, where Sound Studio records audio.This program allows you to edit audio files and Sound studio makes audio files.
Editing audio files in sound studio is a pain with Voiceover, however it records very nicely. I have not tried this program for editing.
I am sending along this link which tells about the features of this software. They say that it works quite nicely with, Audio-hijack-pro, however, I don't know what this means for Voiceover users.
Once again, I don't think you can record with this program, however, let me know if I am in correct.
