Which sound treatment tools does Gabrielle Nistico recommend for professional voiceover artists?

I focus less on specific brand-name gadgets and more on getting the room right first. For most voice actors, the core toolkit usually includes:

• Broadband absorption (panels or thick mineral wool/foam) at reflection points
• Bass trapping in corners if the room booms
• A reflection filter or portable booth if you cannot treat a room
• A proper floor solution (rug or carpeting) to cut reflections
• Pop filter and shock mount at the mic

If you tell me about your current recording space (size, walls, budget), I can narrow this down to concrete product types and setups for you.
