iZotope documents Dialogue Isolate as an ML separator with three gain controls, a Sensitivity control that it says trades noise removal against artifacts and dialogue clarity, a Good/Real-time vs Best/Offline mode (Advanced), and four-band scaling. Scene Rebalance adds a Voice/Music/Effects split whose voice Sensitivity keeps more breaths but can leak other elements. Release notes record an offline-mode defect (muffled end of selection) fixed in 11.2.0. The one first-person review read reports artifacts when the noise control is pushed and a disappointing Repair Assistant result. No source here measures quality.
