Step-by-Step Guide to Reducing Background Noise in OBS
Step 1: Open OBS Studio and Access Audio Settings
Launch OBS Studio on your computer.
Go to the "Sources" panel and find your microphone source.
If you haven’t added a microphone yet, click the "+" button in the Sources panel and select "Audio Input Capture."
Choose your microphone from the list and click "OK."
Step 2: Add a Noise Suppression Filter
Right-click your microphone source and select "Filters."
Click the "+" button in the Filters menu and choose "Noise Suppression."
OBS will give you two options:
Speex (Default) – Uses less CPU but provides moderate noise reduction.
RNNoise (Advanced) – Uses AI-based suppression for better background noise removal.
Select RNNoise for the best results.
Step 3: Apply a Noise Gate for Better Control
Click the "+" button again in the Filters menu and select "Noise Gate."
Adjust the following settings:
Close Threshold: Set this to around -45 dB (adjust as needed).
Open Threshold: Set this slightly higher, around -40 dB.
Attack Time: Set to 25ms (how fast the gate opens).
Hold Time: Set to 200ms (how long the gate remains open).
Release Time: Set to 150ms (how quickly it closes).
This will ensure your microphone only picks up your voice while cutting out background noise.
Step 4: Add an Expander for a Cleaner Sound
Click the "+" button in the Filters menu and select "Expander."
Adjust the settings:
Ratio: 2:1 or 3:1 for mild noise reduction.
Threshold: -40 dB (adjust based on your environment).
Attack Time: 10ms.
Release Time: 100ms.
This will help smooth out audio inconsistencies and further reduce unwanted noise.
Step 5: Test Your Audio and Fine-Tune
Speak into your microphone and monitor the audio levels in OBS.
Adjust the Noise Gate and Expander settings until background noise is minimal.
If necessary, tweak the Noise Suppression filter to find the best balance between clarity and noise reduction.
Bonus Tips for Even Better Audio
Use a dynamic microphone instead of a condenser mic to reduce background noise.
Keep your microphone close to your mouth and reduce gain levels.
Record in a quiet environment and use soft materials (like carpets or foam panels) to absorb background noise.
Use RTX Voice (for NVIDIA GPU users) or third-party noise suppression software for advanced noise reduction.
