Voice Recording Tips: Microphone Selection and Technique
Voice recordings for podcasts, narration, and video rely on proper microphone selection, positioning, and room setup. Small adjustments in technique make a larger difference than expensive equipment upgrades.
Key Takeaways
- Robust, noise-rejecting, and forgiving of imperfect rooms.
- Distance:** 15-20 cm (6-8 inches) from the mouth
- Set the microphone gain (on the interface or USB mic) so normal speaking voice peaks at -12 to -6 dBFS on the meter.
- It is always better to record too quietly (fixable with post-production gain) than too loudly (clipping is permanent damage).
Microphone Types for Voice
Dynamic Microphones
Robust, noise-rejecting, and forgiving of imperfect rooms. Dynamic mics like the Shure SM7B and Electro-Voice RE20 are broadcast standards because they focus on the sound source directly in front while rejecting room reflections and background noise.
Best for: Untreated rooms, noisy environments, deep voices.
Condenser Microphones
More sensitive and detailed than dynamics. Large-diaphragm condensers (Audio-Technica AT2020, Rode NT1) capture subtle vocal nuances — breath, sibilance, room ambience. This sensitivity is a double-edged sword: they sound stunning in treated rooms and terrible in reflective rooms.
Best for: Treated rooms, singing, detailed narration.
USB Microphones
All-in-one mic + audio interface for simplicity. The Blue Yeti, Samson Q2U, and Rode NT-USB Mini produce excellent voice recordings. The trade-off is less flexibility — fixed preamp gain, no external processing chain.
Best for: Beginners, portable setups, video calls.
Positioning Fundamentals
- Distance: 15-20 cm (6-8 inches) from the mouth
- Angle: Slightly off-axis (15-30 degrees) to reduce plosives
- Height: Microphone capsule at mouth level or slightly above
- Pop filter: 5 cm from the microphone, between mic and mouth
Gain Staging
Set the microphone gain (on the interface or USB mic) so normal speaking voice peaks at -12 to -6 dBFS on the meter. This provides headroom for loud moments (laughter, emphasis) without clipping. It is always better to record too quietly (fixable with post-production gain) than too loudly (clipping is permanent damage).
Common Voice Recording Problems
| Problem | Cause | Fix |
|---|---|---|
| Plosive pops | Direct air blast on mic | Add pop filter, speak off-axis |
| Sibilance (harsh 's') | Proximity, bright mic | Move back 5 cm, angle more off-axis |
| Boomy bass | Proximity effect | Increase distance to 20-25 cm |
| Roomy echo | Hard reflective surfaces | Add acoustic treatment, closet trick |
| Background noise | Environment | Use dynamic mic, treat room, noise gate |
