Everybody hates static noise, especially if they are trying to watch a live stream but it is ruined by it. For the viewer, there is nothing to be done about static noise, 9 times out of 10 they will just go and watch someone else. You have probably lost countless viewers over time because they don’t like listening to static, so this guide will tell you how to prevent it, by setting up a noise gate. This can be used to prevent keyboard, controller or static noise.

What does a noise gate do?

A noise gate is software used to remove any sound below a given threshold. If the input sound is above a given threshold, the gate will “open” and allow sound to pass through. If the input sound goes back below the given threshold, the gate will “close” again, and no sound will pass through. This can be used to remove keyboard, mouse and controller noise, or to remove static noise. When the gate is “open” all noise, including the static, will pass through but it will be less noticeable while you’re talking. When the gate closes again, the noise will be gone. We will be using the ReaPlugs Microphone filters to set this up, in particular the “Reagate”.

How to install the ReaPlugs Microphone filters

  1. Firstly you download the ReaPlugs from here
  2. Reaper make many useful microphone filters for streamers like you and I, they will all boost the sound quality of your stream which could make a huge difference to your viewer count. We generally suggest using the Reaper filters rather than the built in ones as they are usually higher quality, and allow more precise customisations to different options, when compared to the built in ones.

  3. Then you open the file, give it permissions and agree to the License agreement
  4. Next, it gives you options of which filters to install. We recommend installing all of them, so that you can use others in the future, however we will only be using the ReaGate in this guide.
  5. Select where you want the files to be installed to, and press install. The ReaPlugs Filters are now installed. We recommend restarting your device.

How to setup a noise gate

We will be using Streamlabs OBS, but this will work in any recording/Streaming Software

  1. Once you are in your chosen software, add your “audio input capture.”
  2. Right click on the Input, and select “filters.”
  3. Filters in streamlabs obs
  4. Add a filter, and for the type select VST 2.X Plugin.
  5. Select the new filter, and on the drop down menu titled “{Please select a plug-in}” select Reagate-standalone.dll, then press “Open Plug-in Interface.”
  6. This interface will open up. It looks very complicated, but in reality it is fairly simple to use. We won’t be changing anything except the “-inf DB” on the left.

  7. With your microphone unmuted, there should be green lines going up on the left hand side. The position of the black bar will be where the gate opens Slide the black bar up, so that It is above the green lines. This will make it so that the static noise is ignored, but you will need to speak louder than the bar. This will change the “-inf” to a negative number

  9. Now, press the record button, try to talk and stop talking. Listen to the recording, and see if you can hear the keyboard, controller or static noise. If you can’t, can you hear your voice? If that’s the case then perfect, although you might need to change it a bit more to ensure that it is perfect. We reccomend playing a game while recording and talking as though you were live, then play it back to see if it sounds ok. If you can still hear the noise you don’t want, then you should move the black bar up, and repeat steps 5-6.
  10. Keep doing this until you reach the sound quality that you desire. If this doesn’t prevent the static noise, we suggest researching other microphone problems, or buying a new microphone.

And that is how you setup a noise gate to remove background sound, keyboard and controller clicks or even static noise from your stream!
