Switch off anything noisy, like ceiling fans, televisions and so on. Check for nearby devices which might cause interference. Move the dial up and down until you find the right balance of sound volume and background noise. Check the box marked Use ambient noise reduction. Find Sound preferences and look for the Ambient Noise Reduction tool. Go to Listen to this device, then click OK. To test the noise, go back to the Recording menu. If they aren't already ticked, tick the following boxes: Noise suppression and Acoustic echo cancellation. Next, go to the tab marked Enhancements. Move the dial all the way up on the Microphone. Move the dial all the way down on the Microphone boost. Find the Levels tab, and look for the Microphone Boost tool. Right-click on the Microphone bar, and then select Properties. This is how to minimise background noise on laptop recordings. Follow the steps below for tips on how to minimise background noise from an audio recording. To some extent, any sound recording will generate background noise, but there's a lot that you can do to minimise interference. I´m all in for max.Background or 'ambient' microphone noise can be a real pain, but there are tricks to help reduce it. I used to crank it up to 320kbps for my DJ streams and it was needed, but until you start doing creative music/audio based streams (and you can make sure that all your audio material like songs have the needed bitrate), its a waste and additional load for the viewer that he has to squeeze into his connection (and it is sometimes pretty bad). 
On stream where you have multiple audio sources, it is impossible to tell the difference. You CAN hear the difference between the 128kbps and 320kbps AAC, but in a clean environment, with a single (well known to you) audio source like your fav. Like spotify (non-premium), most online radio stations and all kinds of live content. This is the reason why most streamers go with the pretty expensive and bulky condenser microphone option sooner or later.īitrate: 128kbps is the "standard" bitrate for many things. But remember, thats only a little bit of help, it cant make gold out of shitty audio quality coming in. You can route that through Audacity or other plugins/standalone solutions and then corrent the additional latency in OBS, this will give you all kinds of filters and effects to clean up the audio.
