Working in the domain of audio, we can sometimes get a lot of useless and unpleasing sounds such as hissing, humming, clicking, and general unwanted elements. Luckily you won’t be the first person experiencing this, with the help of a noise gate/expander we can eliminate a lot of these unwanted sounds through an easy process.
With a wide range of noise gate/expander plugins in the market, each possessing its own unique features, many people face a hard time in selecting the most suitable gate/expander for their particular needs.
So in this article, we will be reviewing 10 of the most efficient and popular plugins. In addition to that, we added a list of the top free noise gate plugins as a bonus down below!
What Does Noise Gate Do?
A noise gate is a type of effect you can add to your channel strip. The gate will affect the sound by completely eliminating the sound below or above a certain threshold, depends on your parameter settings.
Here are the main parameters you would use to effect the noise gate and operate it to your liking.
The Threshold is the control for which level the gate will affect your signal.
Attack, is the time taken for the gate to open.
The Release refers to how long the gate will take to fade out.
Hold is how long the gate will be open for and hold its state.
Range will set how much the signal is reduced when the gate is closed.
Difference Between A Gate And An Expander?
Gate & Expander are very similar but they have a subtle difference.
Gate – Cuts out unwanted signal completely
Expander – Compresses unwanted signal to make it less prominent
Noise gate short history:
1969 – Gating technique developed, and adopted by The Beatles.
1980 – Gating technique implemented in real-time electronics in a few audiophile, high fidelity record players.
1990 – Used vigorously in music production and sound engineering.
Where Do You Place A Noise Gate?
Well, typically the rule of thumb is you wouldn’t want to use a noise gate during recording as you won’t be able to obtain any of the audio data lost at later a date. So to avoid this we recommend applying this effect after you have recorded your audio.
It is also a good idea to have in mind what you want to affect with the gate. For example, you may have a drum break that has a really tight kick and snare but you’re not a fan of the hi-hats. Now you know what you want to achieve so you can tweak the gate to your desired needs.
There are many applications for a noise gate, some offering sidechain features, and others allowing you to invert the signal. This effect can be used in a million different ways.
Why Should I Use The Noise Gate/ Expander Plugin?
If you are involved in music production these tools can be your savior for precisely removing unwanted elements of the sounds. You may also find yourself using it in many creative ways, such as a sidechain trigger.

10 Best Noise Gate/Expander VST, AU, AAX Plugins 2021
10. Unfiltered Audio G8 Review
G8 Dynamic Gate is a multipurpose gate that all producers and audio engineers should adopt. ‘Cycle’ mode will allow you to use it as a stutter effect, AM/Granular effect, or a tremolo. Wet/Dry mix gives the user full control over the amount of the signal being output by Dynamic Gate. ‘One-shot’ mode allows users to have in-depth transient shaping which, can be used to shape the signal sound.
You can also combine it with a MIDI trigger or audio channel to trigger it with G8.
With the new edition of ‘dark’ skin for G8, it blends in perfectly with your DAW and offers enough options to keep your gating needs at bay.
- Cycle mode which keeps repeating the gate envelope endlessly as long as the gate is open. The speed of this repetition is determined by the envelope and the delay controls
- One-shot mode that triggers one full cycle of the envelope as soon as the incoming signal surpasses the threshold
- Reject Outputs feature is probably the best feature for this plugin. Instead of throwing rejected G8’s (or gated out), it sends the signal to an auxiliary output which in turns routes it to another channel in the DAW for the user to edit its panning, leveling and just process it differently which can be extremely useful as it prevents signal loss
- Flip button which can be used to swap gated and rejected signals
Unfiltered Audio G8 works on Windows 7 or higher for PC and OSX 10.9 or higher for Mac. It only supports 64 bits version and comes in VST/VST3/AU/AAX versions.
9. Sonalksis SV 719 Gate Review
Sonalksis SV 719 Gate isn’t so well known but it’s a powerful gate/expander plugin that definitely should be on this list.
There are three modes in this plugin, which are: ‘Duck’, ‘Gate’, and ‘Expand’ each offering a different algorithmic process. Additionally, the SV 719 includes a filter capable of low, mid, and high band filtering.
With a built-in output gain, the levels are easily movable. Moreover, the intuitive A/B switch will allow the user to quickly switch between gating/expanding or ducking ideas.
Giving this all in a compact and beautiful GUI Sonalksis has really created an all-rounded gate/expander plugin that makes a difference to your channels.
- Modeled after an actual analog processor which can make drums have that gated effect and many more
- Expansion mode allows the track to have noise reduction for difficult noise like background interferences and slight noises
- The ducking mode can reduce the impact of the effect in the presence of vocals or when the mix gets busy. This helps reduce cloudiness or muddiness that tends to happen a lot when using noise gates. This is done with the help of an external side-chain that the plugin is equipped with
This plugin requires Windows 7 or higher for PC and OSX 10.9 or higher for Mac. This plugin only comes in VST/AU versions which makes it not compatible with Pro Tools. It has support for both 32 and 64-bit devices.
8. kiloHearts Gate Review
kiloHearts Gate is a simple to use but extremely effective gate when used in practice.
This Gate offers a quick way to cut out a low hum or noise within the signal. Sidechain, look ahead, and the ever-helpful flip feature gives Kilohertz Gate effective simplicity.
Simple selection of controls such as an attack, hold, release, and threshold. But Kilohertz Gate doesn’t offer anything more than what it says on the tin, you can use it in series with the other kilohertz plugin collections but as a stand-alone gate, this is a top contender.
- Look ahead feature which has a 5ms headstart to the plugin, allowing it to anticipate transients and attack them accordingly
- A tolerance knob which is used to set a point where the gate will close if the signals drop below that
- Sidechain which allows the user to set a ducking effect which de-emphasizes the noise gate when the track gets busy to avoid muddiness and cloudiness of the mix
- kiloHearts Gate’s interface is a resizable one which makes it convenient to use with multiple DAWs and multiple screen sizes
kiloHearts Gate works on Windows 7 or higher for PC and OS X 10.6 or higher for Mac. It comes in VST/VST3/AU/AAX versions and supports both 32 and 64 bit systems.

Oxford Drum gate is one of the most highly advanced, intelligent, and innovative dynamic processors in the market, and that shows in its ability to distinguish and separate wanted and unwanted signals.
The plugin is made up of 3 tabs. Each tab consisting of options relating to a separate characteristic of drum processing.
The first tab is the main tab and is in charge of the “detection” part of the operation.
The second tab is the decay tab which gives the user ability to manipulate the signal more precisely.
The last tab allows the user to do the traditional input gating and dynamically control the remaining transients after fine-tuning the gate settings.
- Graphical display for the first tab and shows the transients of the input signal
- Oxford Drum gate allows the user to choose from three modes namely Kick, Snare, or Tom mic. This gives the plugin idea of what it’s going to be dealing with and process it accordingly as well as offer the user a starting point for easier and faster processing
