If you only buy one thing
Fix your room first, then get a RØDE NT1 Signature.
The room matters more than anything you buy. Record in a closet full of clothes, or hang moving blankets around you. Then get a condenser like the RØDE NT1 Signature and plug it into a small interface. It's extremely quiet, the shock mount and pop filter come in the box, and a lot of voice actors never replace it.
If the mic shows up echo, the fix is the room, not a dynamic mic. Record in Audacity for free to start. And if you have no interface and want the simplest possible start, a USB mic like the ATR2100x-USB plugs straight into your computer. It's a fine first step, just not our pick.
- Your space. A closet full of clothes, or blankets around you. The room matters more than the mic.
- A condenser mic and an interface. The NT1 Signature and an SSL 1 are the pair we'd start with.
- Closed-back headphones, so you hear what you really sound like.
- A stand and a pop filter, so the mic stays put and your P's stay soft.
- Editing tools, once you're sending auditions every week.
