Recording Audio
Sound That Doesn't Ruin Your Video
Bad audio kills good video. Viewers tolerate poor visuals but abandon poor sound.
Why Audio Matters
First Impression
Bad audio signals amateur content immediately.
Comprehension
If they can't hear you clearly, your message is lost.
Retention
Good audio is comfortable. Bad audio is fatiguing.
Professionalism
Quality audio separates serious creators from hobbyists.
Microphone Options
Built-In (Phone/Laptop)
Last resort. Picks up everything, sounds distant.
When acceptable: Casual content, informal style
Lavalier (Lapel) Mic
Clips to clothing, close to mouth.
Pros: Consistent sound, hands-free, affordable Cons: Visible, can rustle against clothing Good options: Rode SmartLav+, Hollyland Lark
USB Microphone
Connects directly to computer.
Pros: Easy setup, good quality, affordable Cons: Tethered to computer Good options: Blue Yeti, Audio-Technica AT2020, Rode NT-USB
Shotgun Microphone
Directional, mounted on camera or boom.
Pros: Captures speaker, rejects surroundings Cons: Need to be pointed correctly Good options: Rode VideoMic, Deity V-Mic
XLR Microphone
Professional standard. Requires audio interface.
Pros: Best quality, most options Cons: More complex, more expensive
Recording Environment
Quiet Space
Turn off HVAC, fans, appliances. Close windows.
Room Treatment
Hard surfaces create echo. Soft surfaces absorb sound.
Quick fixes:
- Record in closet (clothes absorb sound)
- Hang blankets
- Use area rugs
- Avoid empty rooms
Background Noise
Listen before recording. You'll be surprised what you didn't notice.
Recording Technique
Microphone Placement
Closer = better (to a point). 6-12 inches for most mics.
Pop Filter
Blocks plosives (p, b sounds). Essential for close miking.
Levels
Not too quiet (adds noise when boosted). Not too loud (distortion). Aim for peaks around -12dB to -6dB.
Consistency
Keep position consistent throughout recording.
Room Tone
Record 30 seconds of silence in your space. Useful for editing.
Common Audio Problems
Echo/Reverb
Cause: Hard surfaces reflecting sound Fix: Add soft materials, get closer to mic
Background Noise
Cause: HVAC, traffic, appliances Fix: Eliminate sources, AI noise reduction
Plosives
Cause: Air from P and B sounds hitting mic Fix: Pop filter, angle mic slightly off-axis
Sibilance
Cause: Harsh S sounds Fix: Angle mic, de-esser in post
Inconsistent Volume
Cause: Moving distance from mic, varying energy Fix: Consistent positioning, compression in post
AI Audio Enhancement
Noise Removal
AI tools can remove background noise effectively.
Tools: Adobe Podcast, Descript, Krisp, Auphonic
Voice Enhancement
Clean up voice, remove echo, balance frequencies.
Audio Leveling
Automatic volume normalization.
AI Voices
Generate voiceovers with AI when recording isn't possible.
Tools: ElevenLabs, Murf, Descript Overdub
When to Use AI Fixes
AI audio enhancement is powerful but not magic.
Best approach: Record well, use AI to polish. Fallback: AI rescue for unavoidably bad recordings.
Voice Recording Tips
Hydration
Drink water. Dry mouth sounds bad.
Warm Up
Speak before recording to find your voice.
Read Ahead
Know what's coming so you can deliver naturally.
Energy
Bring enthusiasm. Monotone loses viewers.
Mistakes
Pause, then redo the line. Easier to edit clean takes.
