Clear audio is one of the most important parts of any video. You could have stunning visuals, smooth video speed, and eye-catching video filters, but if the audio is filled with unwanted noise, viewers will get frustrated. That’s where noise reduction and noise suppression come into play.

Many people think they are the same, but they actually work in different ways. Knowing when to use each one can make a huge difference in the final quality of your video. Whether you’re working with a video production company in Dallas or editing on your own, understanding these tools will help you produce professional-quality content.

 

Noise Reduction vs. Noise Suppression: What’s the Difference?

Both noise reduction and noise suppression help to remove background noise, but they don’t work the same way.

• Noise Reduction: This method removes unwanted noise without affecting the main audio too much. It works best when the noise is steady, like a fan, air conditioner, or hum from an electrical device.
• Noise Suppression: This technique lowers unwanted sounds in real time. It’s great for live recordings, but it can sometimes affect the clarity of voices and other important sounds.

The key difference is that noise reduction works best for consistent background noise, while noise suppression is better for unpredictable noises like people talking in the background or sudden loud sounds.

 

When to Use Noise Reduction

If you’re editing pre-recorded audio, noise reduction is usually the best option. It allows you to remove background noise without affecting the quality of voices or music too much. Most editing software has built-in tools to handle noise reduction.

Here are some common scenarios where noise reduction works well:

• Interviews recorded in a room with a humming air conditioner.
• Voiceovers that pick up computer fan noise.
• Outdoor recordings with mild wind noise.

 

When to Use Noise Suppression

Noise suppression is useful for live recordings or videos where you don’t have time to edit the sound afterward. It reduces noise while the audio is being recorded, making it ideal for:

• Live streamingBroadcasting live video to an audience over the internet, which can be viewed as it is being recorde... where you can’t edit the sound later.
• Video calls or online meetings.
• Recording in noisy environments like cafes or crowded streets.

However, noise suppression can sometimes cause a “robotic” effect on voices because it aggressively filters out background noise.

 

How to Use Noise Reduction in Video Editing

Most video production companies in Dallas professionals use noise reduction software to clean up audio. You can do it too with the right tools.

• Step 1: Choose the Right Software – Some of the best video editing software includes noise reduction tools, like Adobe AuditionA trial performance where actors read specific parts from the script or perform a scene, allowing th..., Audacity, and Final CutThe last version of the film after all editing decisions have been made, ready for rendering and fin... Pro.
• Step 2: Identify the Noise – Select a short section of your audio that only contains the background noise.
• Step 3: Apply the Noise Reduction Effect – The software will analyze the noise and remove it throughout the recording.
• Step 4: Adjust the Settings – Play around with the strength of the noise reduction to find the perfect balance.

Overusing noise reduction can sometimes make voices sound unnatural, so don’t go overboard!

• Test your noise suppression settings before you start recording.

 

Other Editing Tricks for Better Sound

Besides noise reduction and suppression, there are other ways to improve your audio quality.
