Eliminate White Noise in OBS for Crisp Audio Quality

May 17, 2024

There’s nothing more distracting for viewers than poor audio quality when they’re tuning into your live streams or recordings. One common issue is white noise, which can make you harder to hear and sound unprofessional – not a great first impression! Thankfully, OBS (Open Broadcaster Software) has tools to help you proactively address this problem. In this article, we’ll discuss how to filter out white noise in OBS for improved audio quality on your streams and recordings.

Step 1: Understanding White Noise
White noise is a type of static sound that is generated by random frequencies. It's often linked to audio devices, like microphones, and ambient sounds in the background. By using filters within OBS, we can help to eliminate this unwanted noise.

Step 2: Apply Noise Suppression

  1. Open OBS and click on the Mixer settings (the gear icon next to the audio levels).

  2. Select ‘Filters’ from the dropdown menu.

  3. In the audio filters window, click the ‘+’ sign to add a new filter.

  4. From the list of filters, choose ‘Noise Suppression.’

  5. Name the filter to your preference and click ‘OK.’

Step 3: Adjust the Noise Suppression Settings

  1. Once you've added the noise suppression filter, you'll see its settings on the right side of the filters window.

  2. Adjust the slider to determine how much noise suppression you need. The further you move the slider to the right, the stronger the noise suppression will be.

  3. Monitor your audio levels and perform a test recording to ensure that your adjustments have effectively eliminated the white noise while preserving your voice.

Step 4: Experiment with Noise Gate
A noise gate filter can also be useful to control white noise in your audio. It works by silencing your microphone when it's not in use and activating it only when it detects a certain volume threshold (for example, when you're speaking). To apply this filter, follow the similar steps as above, but add ‘Noise Gate’ instead of ‘Noise Suppression.’

Step 5: Test and Tweak
Now that you've applied the necessary filters, it's essential to test your audio and make any tweaks needed. Listen to your recordings to ensure the white noise is effectively filtered out and that your voice quality isn't negatively impacted. You might need to fine-tune the filter settings to achieve the perfect balance.

By filtering out white noise in OBS, you'll ensure a more enjoyable and professional experience for your viewers. Remember to experiment with different settings and prioritize clear, crisp audio during your recordings and livestreams.
