A professional stream relies on three core OBS filters to balance your microphone: a Noise Gate to automatically mute your mic when you stop speaking (hiding keyboard typing), a Compressor to even out the volume by making quiet whispers louder and reducing screams, and a Limiter placed at the end of your filter chain (usually at -2dB) to prevent digital distortion and clipping. You can use the Calibrator below to find your specific values.

🎛️ How to apply these filters in OBS?
Mic Configuration & Filters
In OBS, Right Click your Mic source > Filters. Add them in this exact order:
1. Noise Suppression: Add this filter and choose the RNNoise method.
2. Noise Gate: Copy the thresholds calculated by our tool above.
3. Compressor: Copy the tool’s values so your voice is always clear and audible.
4. Limiter: Copy the tool’s value (usually -2.00 dB).
Game Mixing & Auto-Ducking
Right-click your GAME (or Desktop) audio source > Filters, and add a Compressor. This will automatically lower the game volume when you speak:
• Ratio: 30:1
• Threshold: -40dB
• Sidechain/Ducking Source: Select your Mic’s name from the list
Discord Audio Safety
Anti-Screamer Safety: Right-click your Discord track > Filters, and add a Compressor (Ratio 4:1, Threshold -20dB) to automatically smooth out your friends’ screams when they get jumpscared.
Music & Atmosphere
The Golden Rule: The volume bar for your Music track in OBS should never go past the middle of the green zone (-30dB). The goal is to fill the silence, not force the viewer to listen to your playlist.
The perfect Decibel (dB) balance in OBS settings
For the best OBS audio settings, here is the exact matrix of sound levels to follow on your audio mixer. Your voice must always dominate the mix.
OBS Audio Source
Target (Average dB)
Role in the Mix
🎤 Microphone (Voice)
-12 dB
Main element. The limiter must cap peaks at -2 dB.
👥 Voice Chat (Discord)
-15 dB
Must be clear but slightly quieter than the streamer.
🎮 Game Audio
-18 dB to -24 dB
Audible without masking the voice (at least 6 dB under the mic).
🎵 Background Music
-24 dB to -30 dB
Subtle atmosphere. Must never distract the audience.
Creator Data 2026: Studies show that poor audio quality (echo, unbalanced game volume, saturation) is responsible for 68% of instant viewer bounce rate within the first 30 seconds of joining a Twitch stream.
FAQ: Everything about OBS audio settings
What is the best audio setting for the mic?
The best setting is to use our calibrator to find your unique values, then apply a filter chain: Noise Suppression, then Compressor, and finally a Limiter at -2dB.
How to remove game echo on OBS?
This is a monitoring issue. Go to the OBS Audio Mixer > Advanced Audio Properties, and set your Game source to “Monitor Off”.
