Noise Gate vs. Noise Suppressor | 2024 Comparison🆚

Discover the key differences between Noise Gates and Noise Suppressors. Learn how these audio tools can enhance your audio quality by managing background noise and unwanted sounds effectively.

It's annoying when you are having fun playing with your guitar amp, and you are pestered continually by unwanted noises such as hum, hiss, or feedback. Extracting instrumentals from a song can be a cure sometimes.

But noise suppressors and noise gates are more common solutions to this problem. In many cases, a combination of both noise suppression and a noise gate may be necessary to achieve the desired results. Still, what are the differences between noise gates and noise suppressors?

What Is Noise Gate

A noise gate is a dynamic processor used to control the volume of audio signals. It works by allowing audio to pass through when it exceeds a certain volume threshold (above the "gate" level) and attenuating or muting the audio when it falls below the threshold.

This is particularly useful for reducing or eliminating low-level background noise or unwanted sounds during silent parts of an audio recording.

The best noise gate pedals for musicians and guitar players are game changers facing irksome noises. MXR Smart Gate, ISP Decimator II – G String, and Boss NS-2 noise gate pedals are the best ones available on the market. They usually feature a control knob to set the trigger level for the audio signal. They help mitigate hum or noise between notes greatly.

Most DAWs (digital audio workstations) often pack a built-in noise gate to control the volume of the audio source based on a set threshold. It involves audio editing software Audacity, FL Studio, Ableton, Logic Pro, Premiere Pro, and more. OBS noise gate is also a prime example, which resembles audio ducking OBS.

What Is Noise Suppressor

Noise suppression is an audio processing device or software filter designed to reduce or remove background noise from your audio.

It works by analyzing the incoming audio and identifying frequencies and patterns that match the noise, which could include sounds like hum, hiss, or consistent background noise.

The noise suppressor then applies processing techniques to reduce the volume of these noise elements while preserving the primary audio source, resulting in cleaner and more polished audio recordings or live audio.

Similar to Windows audio ducking, noise suppressors are commonly used in audio production, broadcasting, podcasting, and live sound reinforcement to enhance audio quality by minimizing distracting background noise.

Likewise, when it comes to noise suppression, Audacity, Adobe Audition, OBS, etc. are certainly contenders.

Noise Gate vs. Noise Reducer: Which Is Better

While noise gates and noise reducers go hand in hand, they have subtle differences. A noise gate silences sound that fall beneath a specific threshold, while a noise suppressor merely diminishes sounds below a particular level.

Noise gates are useful to get rid of inactive moments, keyboard clicks, or room noise in audio recordings or live performances. Noise suppression is effective for permanent noise from sound.

There is no preferential weighting of one or another of the battle between noise gate vs. nose compressor. The choice is really up to your specific audio needs.

If you have constant background noise throughout your audio and want to clean up audio continuously, a noise reducer is a better choice. If you need to manage intermittent or noisy sounds during quiet moments, a noise gate is more suitable.

On many occasions, they can be used together to achieve the best results. That's why many audio editors provide both tools.

Remove Unwanted Noise from Audio Online

Step 2. Click "Choose File" or drag and drop the file in the area and wait for the AI analysis.

Step 3. Download the final work with noise removed.

Wrapping up

In conclusion, the choice between a noise gate and a noise reducer depends on your specific audio needs. Noise gates are excellent for managing periodical or undesired sounds during quiet moments, while noise reducers are effective at continuously eliminating constant background noise, enhancing overall audio clarity.

For those looking to enhance their audio further, tools like EaseUS Online Vocal Remover can also be valuable in isolating vocals and removing unwanted elements from audio recordings.

Noise Gate vs. Noise Reduction FAQs

1. Should noise suppression or noise gate go first?

If you have consistent background noise throughout your audio and you are concerned with the clarity of a spoken voice, it's generally better to apply noise suppression first. But if you have occasional, transient noise or you have silence between notes or passages in musical recordings, placing the noise gate first can help mute these noises.

2. What is the difference between a noise suppressor and noise gate OBS?

In OBS, noise suppressors and noise gates are audio filters with distinct roles. Noise suppressors combat constant background noise, while noise gates mute audio during silence. Combining both improves audio quality for streaming or recording, with suppressors handling consistent noise and gates managing fitful sounds, enhancing your audio output in OBS.

3. Are noise gates worth it?

Noise gates can be highly valuable tools for improving audio quality in various contexts, especially when dealing with background noise during silent periods.
