Introduction

“Why does my screen recording sound like a helicopter is landing in the background?”
Whether you’re presenting on Zoom, creating a Loom tutorial, or streaming on OBS, background noise can sabotage your professionalism. But you don’t need a studio mic or expensive software to fix it.

In this 2024 guide, you’ll learn how to remove noise from screen recordings using free tools, native settings, and AI magic. We’ll cover Zoom, Loom, and OBS—with step-by-step fixes for both real-time cleanup and post-editing. Let’s silence the chaos!7

Why Screen Recordings Pick Up So Much Noise

  • Laptop Fans: Overheating CPUs during long recordings.

  • Keyboard Clicks: Mechanical keyboards or noisy typing.

  • Ambient Noise: AC units, pets, or street traffic.

  • Mic Quality: Built-in mics often lack noise suppression.


Method 1: Remove Noise from Zoom Recordings

Step 1: Enable Zoom’s Native Noise Suppression

  1. Open Zoom > Settings > Audio.

  2. Under Suppress Background Noise, select “High”.

  3. Check “Echo Cancellation” to reduce room reverb.

Step 2: Use AI Tools for Post-Recording Cleanup

  • Krisp.ai (Free Tier):

    1. Upload your Zoom recording to Krisp.ai.

    2. Toggle “Noise Cancellation” and “Echo Removal”.

    3. Download the cleaned MP4 or MP3.

  • Audacity (Advanced Control):

    1. Import your Zoom recording.

    2. Use Noise Reduction (Effects > Noise Reduction > Get Noise Profile).

    3. Export and re-sync with video via DaVinci Resolve (free).

Pro Tip: Wear headphones to prevent mic feedback!


Method 2: Clean Audio in Loom Recordings

Step 1: Adjust Loom’s Built-In Settings

  1. Open Loom > Settings > Microphone.

  2. Enable “Noise Suppression” (beta feature as of 2024).

Step 2: Post-Process with Free AI Tools

  • Adobe Podcast Enhance (Free Beta):

    1. Upload your Loom video to Adobe Podcast Enhance.

    2. Download the AI-enhanced file (voices cleaned, noise removed).

  • Descript:

    1. Import your Loom recording.

    2. Click “Studio Sound” for one-click noise removal.

Pro Tip: Record in a carpeted room to reduce echo.


Method 3: Remove Noise from OBS Recordings

Step 1: Set Up Real-Time Noise Suppression

  1. In OBS, right-click your mic source > Filters.

  2. Add “Noise Suppression” and “Noise Gate”.

  3. Adjust settings:

    • Noise Suppression: -30 dB.

    • Noise Gate: Close at -50 dB, Open at -30 dB.

Step 2: Use NVIDIA RTX Voice (For GPU Users)

  1. Download NVIDIA RTX Voice.

  2. Select your mic in OBS and enable RTX Voice as a filter.

  3. Result: Keyboard clicks, fan noise, and background chatter vanish.

Pro Tip: Pair with a dynamic mic like Samson Q2U for crisp vocals.


Method 4: Fix Existing Recordings (Free Editors)

Tool 1: Audacity

  1. Noise Profile: Select a silent section > Effects > Noise Reduction > Get Profile.

  2. Apply to entire track (12 dB reduction max).

  3. Equalize: Boost 1-4 kHz for vocal clarity.

Tool 2: Kapwing

  3. Export without watermarks.

Tool 3: Krisp.ai

  • Works on pre-recorded files (free plan: 60 mins/week).


5 Mistakes to Avoid

  1. Overusing Noise Gates: Can cut off speech beginnings.

  2. Ignoring Mic Placement: Keep mics 6-12 inches from your mouth.

  3. Skipping Headphones: Prevents echo from speakers.

  4. Maxing Suppression: Causes robotic artifacts.

  5. Forgetting Room Treatment: Use blankets/foam for cheap soundproofing.


FAQs

1. Can I remove noise from a recording after saving it?

Yes! Use Audacity or Adobe Podcast Enhance to clean pre-recorded files.


2. Why does OBS still pick up noise with filters?

Your mic may be too sensitive. Lower gain and add a physical pop filter.


3. Best free tool for Zoom noise removal?

Krisp.ai (real-time) or Audacity (post-processing).


4. How to remove keyboard noise without a noise gate?

Wrap your keyboard in a towel or use a dampening O-ring.


Free Checklist for Noise-Free Recordings

✅ Test mic settings before recording.
✅ Use Krisp.ai or RTX Voice for real-time cleanup.
✅ Export cleaned audio separately (never overwrite originals).
✅ Invest in a $20 foam panel for wall reflection.
