Do I need acoustic treatment for voiceover?

Yes, acoustic treatment makes a bigger difference than microphone choice. An untreated room adds reflections, flutter echo, and room tone that mark recordings as amateur. At minimum, hang moving blankets or acoustic panels behind and to the sides of your recording position. A dedicated vocal booth or reflection filter helps significantly. A $100 microphone in a treated space sounds better than a $500 microphone in an untreated room.

What audio interface do I need for voiceover?

A single-channel interface with a clean preamp is sufficient. The Focusrite Scarlett Solo ($100) and Audient iD4 ($200) are industry favorites for solo voiceover. Key specs to check: preamp gain (60+ dB for dynamic mics), low self-noise, and reliable drivers. If using a high-output condenser like the AT2020, almost any modern interface provides sufficient gain. If using a low-output dynamic like the SM7B, choose an interface with 60+ dB gain or add a cloudlifter.
