# Faced with a noisy production-dialogue clip, what do the common AI "enhance" and "isolate" tools (iZotope RX, Premiere Enhance Speech, Adobe Podcast, Descript Studio Sound, DaVinci Resolve Voice Isolation) take in, give back and let me control, per their own documentation?

Vendor documentation describes two families. One-control tools return a single processed dialogue track with one blend or intensity control (Premiere Enhance Speech Mix Amount, Descript Studio Sound Intensity; the Adobe Podcast pages read describe no strength control). Component tools split the input and expose per-component gain (iZotope Dialogue Isolate: voice, reverb, noise; RX 12 Scene Rebalance: voice, music, effects). The Resolve 20 guide read shows Voice Isolation as a toggle (Voiceover tool, AI Audio Assistant) but not its parameters; the 209 MB reference manual was not fetched. All statements below are vendor statements, not tests.
