Microphone choice is extremely important. $50 USP mic will not sound like a Sennheiser 416 or Neumann U87.
Regardless of mic, placement is extremely important.
1. Around 5 inches from most studio mics.
2. No farther than 12 inches or you'll begin to get "room noise." Too far off axis and the audio will be unusable.
3. Getting closer than 5 inches can create "proximity warmth," a very intimate and warm sound. Can come in handy for emotional color.
4. If audio is distorted the audio is ruined. Better to have low audio that no audio.
5. With proper mic placement, you won't have a problem.
Vocal EQ can make the audio sound crisp and stand out. But, bad EQ, such as too much bass or too much high end (4k-12K) can make the voice "too bright." We will demonstrate. More great pointers from Larry Jordan's article.
