OBS comes bundled with an expander by default, and for nearly of y'all, it will be more than sufficient for doing the job. However, the MCompressor VST plugin that comes arranged with the MFreeFX bundle easily outperforms the simple expander when running the "Expander preset". In fact, it does this then well that in sure cases, information technology will become rid of background racket in OBS completely, without affecting the tone of your audio in any way. Advertisements

I love VST filters!

I'm not even overstating its capability here; I accept virtually eliminated background noise in its entirety with a few simple tweaks – and a relatively quiet surround, of course. See, over a sure loudness of background noise, the Expander filter will actually eliminate your own voice. The tool is non magic and volition be unable to piece of work beyond a certain volume threshold.

For example, you're one of those individuals unlucky enough to live past a set up of railroad train tracks, or take a construction site nearby, well… sadly, there is only and so much that sound isolation, handling, and filters can do. A railroad train or a construction project is simply likewise much noise to counter. As for some lesser sources of dissonance, such equally noisy family members, etc. then you can look into some room acoustics treatment options that might make it a bit more than manageable. Don't worry, at that place are free options listed in there if you are on a tight upkeep.

If you are able to tame the background racket to a more manageable level; say, around -55dB or less, so this is where the Expander comes into play.

Why the Expander will become rid of groundwork racket in OBS

Then you sympathize, I'k not exactly using the expander as it is intended to be used. Notwithstanding, I doubt that I am the first person to utilize information technology in this style considering I have not been doing this nearly as long as some audio professionals out there. Call it a happy trivial accident, I suppose.

What I did was, In my load order for VST Plugins, I have placed the MCompressor showtime in the list and ready information technology to the Expander preset. From in that location, I tweaked the curve a bit until I ended up with this. Annotation, that very get-go scrap of the graph? That is the key to this whole thing. If y'all elevate that first black Tie-fighter looking icon down, and towards that dot, then it will engage the filter at all times.

The Key to get rid of background noise in OBS is that little dot at the low end.

The Result? See that "Out channel"? There is nothing detected, even though the "In channel" shows an input of -45dB. The groundwork racket was completely eliminated!

Sweet, sweet Silence. The Expander filter was able to get rid of background noise in OBS entirely!

Why does this work so well? There has to be a catch? Correct?

Well, yes, there is of course a take hold of to this little trick, equally I stated at the beginning. Though with an fairly placidity environment, this can be easily overcome with proper microphone speaking techniques.

Here is a Quick table of the Drawbacks for your convienence

Drawbacks	Severity
Will eliminate your own voice in loud settings	Major
Increased CPU Usage while the filter is active	Minor

The sting in the tail is that it will potentially eliminate your own voice if y'all speak likewise softly. This is why I mentioned that it won't work beyond a certain indicate. If your groundwork racket is besides loud, and you gear up the tool to eliminate it with an aggressive setting, information technology will as well work to eliminate your own voice, doing its job. This can lead to choppy audio, where bits and pieces of higher-intensity sounds come through, simply softer sounds are lost to the filter. Yous would practically have to have a screaming lucifer with Goku when he is powering up to Super Saiyan to overcome an over-aggressive filter setting like this.

There is also the Noise suppressor, which will help fight background noise, at the price of sound quality. Every filter has its benefits, and drawbacks.

One terminal, less apparent drawback is the increased CPU usage – about 0.4% or so on an I7 6700k. This isn't much, but every little scrap adds up, and you merely have so much CPU power available. If you are alive streaming a particularly CPU-intensive subject field, this may be plenty to tip the balance of what is acceptable, and what pushes your CPU over the edge.

The best solution – Eliminate the source

Advertisements This filter isn't designed to be your main line of defense. That honour lies with eliminating the source of the groundwork noise – where possible. For instance, in one of the videos over on the Streamer's haven YouTube channel, I forgot to turn off the air purifier during recording. You tin can conspicuously hear the purifier through the phone's microphone. This is a perfect example of an audio source that you accept the ability to eliminate during recordings or alive streaming situations. I left that video up to serve as an excellent example of what-non-to-exercise.

The expander filter is used after everything that tin be eliminated, is eliminated. Then, yous are usually given plenty headroom to set the filter's curve to something manageable, and eliminate room noise without impeding your ability to speak.
