How to Remove Background Noise from Video Free

Step-by-step guide to removing background noise from video files online. Clean wind noise, hum, and ambient sounds from MP4, MOV, and WebM videos.

The Problem with Noisy Video Audio

You shot a great video, but the audio is ruined by wind noise, traffic, or the hum of an air conditioner. Re-shooting isn't an option. Professional video editing software can help, but the noise reduction tools in Premiere Pro or DaVinci Resolve have a steep learning curve.

The good news: you can now remove background noise from video audio online, for free, using AI — no software installation required.

How to Remove Noise from Video Online

Step 1: Upload Your Video

Go to AudioClean and upload your video file. Supported formats include MP4, MOV, WebM, MKV, AVI, MPEG, 3GP, FLV, TS, WMV, and M4V.

Step 2: AI Cleans the Audio Track

AudioClean automatically extracts the audio track from your video, runs it through the DeepFilterNet3 AI noise removal engine, and prepares the cleaned audio. The video stream is left completely untouched — no re-encoding, no quality loss.

Step 3: Preview and Download

Listen to the before/after comparison using the A/B toggle. When you're happy with the result, download your video with the cleaned audio track.

Types of Video Noise AudioClean Handles

Wind Noise

Common in outdoor recordings, vlogs, and travel videos. The AI effectively removes wind noise while preserving speech.

Background Traffic

Street noise, car horns, and ambient city sounds. Use Medium or Aggressive level for best results.

Room Noise

AC hum, computer fan noise, and refrigerator sounds that get picked up by your microphone during indoor recording.

Crowd and Ambient Noise

Background chatter in public spaces. The AI isolates the primary speaker and reduces ambient voices.

Comparison with Video Editing Software

|---------|-----------|-------------|--------|

| Install Required | No | Yes (8GB+) | Yes |

| Video Re-encoding | No | Yes | Yes |

The key advantage of AudioClean: your video is never re-encoded. The video stream is copied bit-for-bit, and only the audio track is replaced. This means zero quality loss for your video.

Tips for Best Results

**Choose the right level:** Start with Medium. If the video was recorded outdoors with wind, try Aggressive.

**Check the preview:** Always use the A/B comparison to make sure the AI didn't remove any important audio.

**Export format:** The output maintains your original video format (MP4 stays MP4, MOV stays MOV).

**File size:** Free tier supports videos up to 300MB (about 2-3 minutes of 1080p). Upgrade for larger files.

FAQ
