How to Remove Background Noise from Video

Have you ever played a video and couldn’t hear clearly? 

Background noise can take many forms—dogs barking at the mail carrier, lawnmowers outside your office, or even sounds from your computer fan and mouse. 

Why background noise removal is important

Clean and crisp audio in your videos is essential to maximize engagement and knowledge transfer. Unwanted noises distract the viewer and divert their attention from your voice and the content you share. 

In a TechSmith study, 35% of viewers reported that high-quality audio narration keeps them engaged. Audio quality is the most critical quality of a video. 

Best practices for high-quality audio

You create videos to convey a message, aiming for viewers to focus on your content without distractions. While you can’t control their viewing environment, you can ensure high video quality by following these best practices and leveraging noise reduction technology. 

• Use the best quality microphone you can afford.
• Locate a quiet space where there are minimal distractions.
• Always run a quick test to ensure audio is being recorded.
• Record your audio or video with a tool that offers noise suppression during recording, like Camtasia.
• Use audio effects, such as noise removal, to enhance or correct audio.
• Add audio filters or sound effects, which can further polish the audio 

Steps to use to remove background noise from audio and video files

Step 1: Upload your video

Pick a video editor that supports multi-track editing. This makes it easy to edit video and audio tracks separately. The market-leading choice is Camtasia.

Then 

1. Start a “New Project”
2. Upload your video file

Step 2: Isolate the audio track

The next step is to extract the audio from the video.

1. Select the video track
2. Right-click and select ‘Separate Audio from Video.’

Alternatively, begin by uploading your audio file or making a new video recording.

Step 3: Use noise reduction features

In Camtasia, click and drag the Noise Removal effect onto the audio track. You can also automatically reduce noise before recording.

In Audiate, 

1. Click the Properties button
2. Click the + icon to view Effects
3. Click to apply the Remove Noise effect

Step 4: Fine-tune the sound quality

Camtasia and Audiate both provide easy-to-use sliders to adjust sound quality.

• Sensitivity: Adjust how frequently the noise removal effect will be applied. When the sensitivity is high, the noise removal will apply even if the noise is soft.
  • Tip: If the audio becomes distorted, lower the sensitivity.
• Amount: Adjust the amount of noise reduction applied. The higher the amount, the more dramatic the noise removal.
  • Tip: If the audio becomes distorted, lower the amount.
