It can remove small background noises such as keyboard clicks and PC fan noise.<\/p>\n\n\n\n<p>Here&#8217;s how to set up noise gate:<\/p>\n\n\n\n<p>1. In OBS&#8217;s &#8220;Audio Mixer,&#8221; click the &#8220;&#8230;&#8221; (ellipsis) left of the application audio capture<br>2. Select &#8220;Filters&#8221;<br>3. Click the &#8220;+&#8221; button and add &#8220;Noise Gate&#8221;<br>4. Set the values as follows for reference<br>   \u30fb&#8221;Close Threshold&#8221;: -40dB to -50dB (cuts sound below this volume)<br>   \u30fb&#8221;Open Threshold&#8221;: -35dB to -45dB (allows sound above this volume)<br>5. Click &#8220;Close&#8221; to finish setting<\/p>\n\n\n\n<p>Noise gate is suitable for cutting small background noises; sounds above the threshold will pass through. Be cautious not to set the threshold too high, as it may interrupt your voice.<\/p>\n\n\n\n<p>If you&#8217;ve already tried using a noise gate in OBS and want to explore additional filters to further improve your audio quality, be sure to check out this article:<\/p>\n\n\n\n<p><a href=\"https:\/\/alive-project.com\/en\/streamer-magazine\/article\/2008\/\">What Is a Noise Gate in OBS? How to Set It Up and How It Differs from Noise Suppression<\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Reduce Environmental Noise with &#8220;Noise Suppression Filter&#8221;<\/h3>\n\n\n\n<p>Noise suppression filter efficiently reduces environmental noises like air conditioning, PC fan noises, or outside background noises.<\/p>\n\n\n\n<p>Unlike the noise gate, noise suppression works regardless of volume, benefiting chat streams, ASMR, or recordings in a quiet environment.<\/p>\n\n\n\n<p>Here\u2019s how to set up the noise suppression filter:<\/p>\n\n\n\n<p>1. In OBS&#8217;s &#8220;Audio Mixer,&#8221; click the &#8220;&#8230;&#8221; (ellipsis) left of the application audio capture<br>2. Select &#8220;Filters&#8221;<br>3. Add &#8220;Noise Suppression&#8221; by clicking the &#8220;+&#8221; button<br>4. Choose from the following under &#8220;Method&#8221;<br>   \u30fbSpeex (low-load, light noise suppression)<br>   \u30fbRNNoise (AI-based, high-accuracy noise suppression)<br>5. Adjust the noise reduction amount with the slider (-10dB to -20dB is guide)<br>6. Click &#8220;Close&#8221; to complete settings<\/p>\n\n\n\n<p>\u25bcSettings Tips<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Speex: Optimal for reducing PC load<\/li>\n\n\n\n<li>RNNoise: Recommended for stronger noise removal (may cause slight delay)<\/li>\n\n\n\n<li>Excessive suppression may lead to muffled or unnatural voice delivery<\/li>\n<\/ul>\n\n\n\n<p>The noise suppression filter accurately analyzes and reduces noises recognized as noise based on certain frequencies. Appropriate adjustments are important to avoid mistakenly filtering out mic sounds or game sounds. <\/p>\n\n\n\n<p>If noise persists even after using filters other than noise suppression, it\u2019s a good idea to review your audio settings in OBS.
