This filter is particularly effective in reducing mild background noise; however, it may not yield optimal results when dealing with a significant amount of noise. There are two methods of noise suppression available: RNNoise, which offers better quality but utilizes more GPU resources, and Speex, which provides lower quality but requires fewer GPU resources.

By using this filter, you can define close and open threshold values. OBS Studio will then filter out any sound that falls outside of this specified volume range. This filter is particularly useful in situations where there is excessive noise.

While OBS Studio is versatile and powerful, it is important to note that it only supports capturing audio alongside the PC screen.

If you solely wish to save the audio file, extracting the audio from the captured video would be a more suitable approach. Fortunately, we have a post that guides you through the process of extracting audio from video recordings with just a few simple clicks.


So that’s how you make your mic sound better when you live stream using OBS Studio by using Noise Suppression and Noise Gate filters.

By following the step-by-step instructions outlined in this article, you can easily leverage OBS Studio’s audio filters to achieve professional-level audio results.
