While creating audio or video content, audio quality plays a significant role in making content engaging. Noise gates and noise reduction tools can enhance audio quality and manage unwanted noise. Both noise gates and noise reduction technologies have their unique strengths and use cases. Understanding the differences and applications of these two techniques is essential to use them effectively.
This article helps you with choosing the right method for your needs. Comparing noise gate vs. noise reduction characteristics, functionalities, and practical applications, you can do effective audio processing.
What Is Noise Gate?
A noise gate is a dynamic audio processing tool to manage and control unwanted sounds or noise in audio recordings. It can reduce or mute audio signals below a certain preset volume threshold. Noise gates help eliminate background noise and enhance the overall audio quality by allowing only the desired sounds to pass through.
How does a noise gate work?
It works like a physical gate or door. When an audio signal surpasses the defined volume threshold, the gate "opens," permitting the audio to flow. Conversely, when the signal drops below the threshold, the gate "closes," effectively silencing or reducing the signal volume. Noise gates allow users to remove breathing from the audio in Garageband.
The primary parameters of the noise gate are:
- Threshold: The level at which the gate opens and closes.
- Ratio: The degree of volume reduction if audio falls below the threshold.
- Attack: How long the gate opens after the signal crosses the threshold.
- Release: How swiftly the gate closes after the signal drops below the threshold.
- Hold: Specify the time to close the gate after the signal dips below the threshold.
Use Cases for a Noise Gate
Noise gates allow users to remove background noise in DaVinci Resolve. Noise gates find application in various audio scenarios, including:
- Live Sound: In live sound, noise gates are used to eliminate feedback, reduce noise, and enhance the clarity of live performances.
- Podcasts: Podcasters use noise gates to reduce ambient noise, such as computer fan sounds or air conditioners.
- Drums: Noise gates can isolate individual drum microphones, preventing bleeding from nearby drums and cymbals.
- Speech Enhancement: It helps reduce background noise, making speech and voice recordings more intelligible.
- Guitar Effects: Noise gates are used in guitar rigs to eliminate unwanted noise generated by high-gain amplifiers and effects pedals.
What Is Noise Reduction?
Noise reduction is a crucial audio processing technology to improve the audio quality by eliminating unwanted background noise. It has the ability to distinguish between the main audio source and background noise. It allows users to manage and manipulate the levels of both components.

How Does Noise Reduction Work?
Noise reduction analyses the audio signal and isolates the background noise from the desired source sound. It uses complex algorithms to differentiate between the two components. Once separated, the user can control and process each component independently. Noise reduction is a powerful tool to improve audio quality when background noise is louder than the desired audio source.
Use Cases for Noise Reduction
Noise reduction helps you with how to remove background noise in Adobe Audition. You can use noise reduction in the following scenarios:
- Audio Post-Production: In film and video post-production, it can remove unwanted noise and hiss.
- Music Production: Musicians and producers use noise reduction to separate background noise from vocal tracks or instruments.
- Podcasting: Podcasters use noise reduction to create professional-sounding podcasts.
- Audio Restoration: When restoring older recordings, noise reduction can remove hiss, crackles, and background noise.
- Voiceover Recording: Voiceover artists use noise reduction to ensure clear and noise-free vocal recordings.
- Field Recording: Field recording professionals can improve audio recorded in noisy or outdoor environments.
Noise Gate vs Noise Reduction
In audio processing, noise gates and noise reduction are two critical components. Both serve distinct purposes in managing and improving audio quality. Here are the key differences between these two technologies.
|Feature||Noise Gate||Noise Reduction|
|Purpose||Reduces or mutes audio below a specified threshold, making it ideal for eliminating background noise.||Targets unwanted noise by distinguishing it from the main audio source, preserving the primary signal's integrity.|
|Functionality||Opens and closes like a gate, muting sounds below the threshold.||Separates background noise from the primary audio and allows independent management.|
|Threshold Control||Sets a specific volume level for gating.||Focuses on the volume of background noise relative to the main audio source.|
|Ratio Control||Adjusts the degree of volume reduction for signals below the threshold.||N/A|
|Attack and Release Time||Determines the speed of opening and closing the gate.||N/A|
|Advanced Processing||Simplifies audio by muting or reducing low-level sounds.||Requires complex algorithms to separate noise and source audio.|
|Use Cases||Ideal for live sound to control feedback and where background noise is significantly lower than the primary source.||Suitable for audio post-production, music production, podcasts, and scenarios with noticeable background noise.|
|Flexibility||Limited in handling complex noise scenarios.||Offers more control for intricate audio cleanup.|

FAQs on Noise Gate vs Noise Reduction
When it comes to managing audio noise, understanding the distinctions between noise gates and noise reduction is necessary. Below are the FAQs to help you enhance your audio
1. What is the difference between a noise suppressor and noise gate OBS?
A noise suppressor and a noise gate Open Broadcaster Software serve similar purposes. However, the key difference is in their operation. A noise gate is an audio tool that mutes or reduces audio signals that fall below a specific threshold. On the other hand, a noise suppressor uses advanced algorithms to identify and reduce or eliminate unwanted noise.
2. Should I use a noise gate?
Noise gates can control and reduce background noise during silence or low-level audio. They are commonly used in live sound for managing feedback and on musical instruments. However, they may not be the best choice when dealing with more complex noise issues. If you want to preserve the original sound quality, choose the noise reduction tool.
3. Does the noise gate reduce background noise?
A noise gate can reduce or mute background noise when it falls below a specified threshold. It is effective in managing background noise during silent or low-volume sections of audio. However, it does not actively reduce background noise; it simply controls when the noise is audible and when not.
4. What is a noise gate good for?
A noise gate is particularly useful for scenarios where there is a consistent background noise or interference that you want to control. It is commonly employed in live sound reinforcement to manage feedback and in music production to mute instrument tracks during pauses.
