After a bit more testing and direct comparison between similar plug-ins, I would say that you definitely get good real-time results with the Accusonus plug-ins. However, they are best when you stick close to their defaults.
I do feel like I get better acoustic results with the iZotope RX plug-ins, especially with real troubled audio, like heavily clipped VO recordings. However, you do have to *apply* the RX effect (at least in Audition) before you will hear clean results. For example, with the Declip example, I can play the Accusonus, push it, and hear clean results. With iZotope, I get crackle in real-time when I push it. But after applying each effect, the iZotope sounded somewhat better to my ears and seemed to do a smoother job of rounding the clips.
For controlling vocal levels, my favorite still remains Waves Vocal Rider. I like the Accusonus Voice Leveler, but it’s basically an intelligent compressor. Vocal Rider actually “rides” its built-in faders, as the name implies. So low and high volume levels are dynamically adjusted, not compressed, thus leaving you with a more open sound.
All things being equal Waves tends to be the first place I look for audio plug-ins. However, you do have to look for their special deals to get good pricing. And you have to handle license activations if you are dealing with multiple machines.
