OK…
But most people here making audiobooks are not audio engineers and 32-effects are out of the question!
The hard part is setting-up a “soundproof” studio and getting a good recording. Then they can run the Audiobook mastering macro, confirm with ACX check, perhaps apply some noise reduction, and they are done!
…It’s usually impossible to meet the ACX standards without limiting so I’m not sure what you’re saying about that. (The peaks & RMS levels have to be set independently and limiting makes that possible.)
