OBS Studio is well-known for being one of the most popular screen recording and streaming apps in the world. This program has numerous complex options for improving your streaming or recording performance, such as an audio mixer with per-source filters. With its assistance, you can minimize or even eliminate the background noise.
Clear audio is an important part of running a good live commentary feed. Any microphone will suffice for offering commentary, but it’s critical that the audio you’re providing comes through with as little background noise as possible. OBS Studio, for example, has many built-in options that assist decrease the background noise while keeping your voice heard.
Let us look at various tools and settings on how to reduce background noise in OBS Studio.
1. Using Filters to Reduce Noise
When the audio source is quiet, use the “Gain” filter to boost the loudness. In a noisy area, however, “Noise Gate” and “Noise Suppression” are what you need to remove or decrease undesirable noises. There are minor changes between the two filters, and this section will explain how to pick between them.
Although OBS studio is diverse and strong, it is worth noting that OBS Studio only enables capturing audio in addition to the PC screen. If you simply want to save the audio file, you should extract it from the captured video.
2. Noise Suppression
This filter is useful for decreasing light background noise, but it is ineffective for dealing with huge amounts of noise. There are two noise suppression methods: RNNoise for greater quality and higher GPU utilization, and Speex for lesser quality and reduced GPU consumption.
3. Noise Gate
Set the near and open threshold settings for this filter, and OBS will filter out any sound that does not fall inside this volume range. When there is a lot of noise, this filter works well.
Noise Gate can be used alone or in conjunction with Noise Suppression. This is mostly determined by the degree of the background noise in your surroundings. If you’ve tried different suppression filter levels and they didn’t help much, you can try adding Noise Gate. Start with the default settings and adjust them to fit your needs.
Because each instance is unique, you should spend some time ahead experimenting with filter settings to discover the ideal levels that work with your audio devices and the surrounding environment.
- To alter the audio settings, locate the “Audio Mixer” module on the main interface and click the gear symbol. It is worth noting that the settings for desktop audio and microphone audio must be adjusted separately. Select “Filter” and then the audio filters you want to use.
- Select any of the noise reduction filters from the filter list by clicking the “+” button in the bottom left corner.
- After you’ve added all of the filters you require, click the “Close” button to apply them and return to the main interface.
You’ve probably heard the saying “Seeing is believing,” but the soundtrack is just as crucial as a video. If your video has a piece of fantastic music, it will sell the material more effectively. The audience would tune out if there was background noise in OBS. To save time, use the five techniques discussed before to eliminate the background noise from video.
4. Reducing the Background Noise from Computer’s Mic
If you’re recording sounds on a laptop or desktop computer, you may manually regulate the amount of background noise that your device takes up. Background noise on microphone input from a laptop or desktop computer might include keyboards, the laptop fan, mouse clicking, and other sources. Your operating system determines how you configure the ambient sound setting on your computer.
If you have a Windows machine, navigate to Hardware and Sound in the Control Panel. After you’ve chosen sound, navigate to the recording area and right-click on the microphone bar. The “levels” tab, which contains the Microphone Boost tool, may be found under the “properties” section. Turn the microphone boost dial all the way down to minimise sound. Also, make sure you turn the microphone dial all the way up.
After you’ve adjusted the mic DSP plugin, go to the Enhancements page and tick the boxes for acoustic echo cancellation and noise reduction. Return to the recording menu and listen to the device to check for noise.
5. Reducing the Background Noise from a Standard Microphone
On a conventional microphone, there are several aspects that contribute to noise reduction. These vary from simple outside noises that may be muffled by shutting a door or a window to electrical interference caused by cords. Perform a fast sweep of your surroundings to decrease ambient noises while using a conventional microphone. Turn off any fans, televisions, radios, or audio output systems that your microphone may pick up on.
Check to see if any neighboring gadgets are producing interference as well. Another issue that you may remedy by rapidly scanning the area is electrical cords flowing across your audio input cables. This can cause an electromagnetic force to interfere with the audio wire, resulting in interference.
By speaking properly into the microphone, you may produce an audio track in which you can subsequently minimize the background noise manually using a program if desired. You may reduce ambient sounds by making sure you’re using the proper type of microphone for the job.
Other variables may contribute to background sounds in your recording. While installing software, altering your gear, or relocating your recording equipment away from sources of ambient noise will significantly reduce the background noise, each performer, room, and microphone will react differently owing to differing sensitivities.
