When it comes to recording audio in OBS (Open Broadcasting Software), one of the most frustrating issues that can arise is background noise. Whether you’re streaming gameplay, podcasting, or conducting online meetings, unwanted sounds can quickly ruin an otherwise high-quality audio experience. Fortunately, OBS provides a range of tools and settings to help you combat noise and ensure your audio is crisp and clear. In this article, we’ll delve into the world of noise suppression in OBS, exploring the different methods and techniques you can use to add noise suppression to your mic.
Understanding Noise Suppression in OBS
Before we dive into the how-to, it’s essential to understand the basics of noise suppression in OBS. Noise suppression, also known as noise reduction or noise cancellation, is a process that eliminates or reduces unwanted background sounds from your audio signal. This can include hums, hisses, fans, keyboard typing, and other distracting noises that can detract from the overall listening experience.
In OBS, noise suppression is achieved through a combination of settings and filters that work together to identify and remove unwanted sounds. The software uses advanced algorithms to analyze your audio signal and distinguish between desired audio (your voice, music, or other intended sounds) and unwanted noise.
OBS offers several noise suppression filters that can be applied to your audio signal. These filters work in different ways to target specific types of noise:
1. Noise Reduction Filter
The Noise Reduction Filter is a built-in filter in OBS that uses a proprietary algorithm to reduce background noise. This filter is designed to target constant, low-level noise such as fan hums, air conditioning, or background chatter.
2. Noise Gate Filter
The Noise Gate Filter is another built-in filter in OBS that’s designed to eliminate sudden, loud noises such as bumps, thumps, or door slams. This filter works by setting a threshold level for your audio signal, and any sounds below that level are muted or reduced.
3. Expander Filter
The Expander Filter is a more advanced filter that’s designed to target dynamic noise such as keyboard typing, mouth noises, or other sudden sounds. This filter works by amplifying or reducing your audio signal based on the input level.
Adding Noise Suppression to Your Mic in OBS

Step 5: Add Additional Filters (Optional)
If you want to add additional filters to your audio signal, you can do so by clicking on the + button at the bottom of the Audio tab. This will allow you to add filters such as the Noise Gate Filter or Expander Filter.
Step 6: Monitor and Adjust
Once you’ve added noise suppression to your mic, monitor your audio signal in real-time to ensure that the filter is working effectively. You can do this by clicking on the Preview button in the Audio tab.
If you notice that the filter is over-correcting or under-correcting, you can adjust the settings accordingly. It may take some trial and error to find the perfect balance, but with patience and practice, you can achieve crisp, clear audio with minimal background noise.
Tips and Tricks for Optimizing Noise Suppression in OBS
While the steps above will give you a solid foundation for adding noise suppression to your mic in OBS, here are some additional tips and tricks to help you optimize your results:
- Use a high-quality mic: A good-quality mic will pick up your voice more clearly and reduce the amount of background noise.
- Position your mic correctly: Experiment with different mic placements to find the spot that picks up your voice the best and reduces background noise.
- Invest in acoustic treatment: If you’re recording in a noisy environment, consider investing in acoustic treatment such as soundproofing panels or a portable vocal booth.
- Use a pop filter: A pop filter can help reduce plosive sounds such as “p” and “t” and prevent loud bursts of air from hitting your mic.
- Monitor your audio signal in real-time: Keep an eye on your audio signal in real-time to catch any issues before they become problematic.
By following these steps and tips, you can add effective noise suppression to your mic in OBS and ensure that your audio is clear, crisp, and free from distracting background noise. Whether you’re streaming, podcasting, or conducting online meetings, noise suppression is an essential tool in your audio arsenal.
What is Noise Suppression and Why is it Important in Streaming?
Noise suppression is a feature in audio processing that helps to reduce or eliminate unwanted background sounds in your audio signal. This is especially important in live streaming, as it can make a huge difference in the quality of your audio. When you’re streaming, you want your viewers to focus on your voice, not the sound of your keyboard typing, the hum of your computer, or the rustling of your clothes.
Without noise suppression, these background sounds can be distracting and take away from the overall viewing experience. By incorporating noise suppression into your streaming setup, you can ensure that your audio is crisp and clear, and your viewers can focus on what you’re saying.
What is OBS and How Does it Support Noise Suppression?
OBS (Open Broadcasting Software) is a popular, free, and open-source streaming software that is widely used by streamers and content creators. One of the key features of OBS is its support for noise suppression through plugins and filters. OBS allows you to add noise suppression to your microphone audio signal, which can be customized to suit your specific needs.
By using noise suppression plugins and filters in OBS, you can reduce or eliminate background noise, hiss, and hum from your audio signal. This can be especially useful for streamers who record in noisy environments or who have older microphones that may pick up more background noise.
What are the Different Types of Noise Suppression Available in OBS?
There are several types of noise suppression available in OBS, including frequency-based suppression, spectral subtraction, and machine learning-based models. Frequency-based suppression involves reducing or eliminating specific frequency ranges that are prone to noise. Spectral subtraction involves subtracting the noise signal from the original audio signal. Machine learning-based models use algorithms to identify and remove noise from the audio signal.
Each type of noise suppression has its own strengths and weaknesses, and the best approach will depend on the specific type of noise you’re trying to remove and the characteristics of your audio signal.
