TL;DR
Ordering OBS filters as Gate first, then Compressor, then Limiter improves sound clarity and consistency. Testing and adjusting these steps can make your streams sound broadcast-quality.
When you hit record or go live, your audio can make or break the viewer experience. A noisy mic, uneven volume, or sudden peaks can distract or even turn off your audience. But the way you order your filters—like Gate, Compressor, and Limiter—can make all the difference. Getting this right turns a shaky mic into a smooth, professional-sounding broadcast.
In this guide, you’ll see how the sequence influences your sound, backed by practical examples and simple tips. Whether you’re a beginner or looking to fine-tune your setup, understanding filter order helps you get the most out of your gear and software.
Place the Gate before the Compressor to prevent background noise from triggering compression.
Use the Limiter as the last filter to prevent clipping and protect your audio quality.
Test your filter settings in real time and tweak thresholds for natural sound.
Avoid over-filtering—less is often more for clarity and naturalness.
Regularly monitor your audio to catch artifacts early and ensure consistent quality.
What Does Filter Order Do in OBS and Why It Matters
Filter order in OBS determines how your audio signal gets processed step-by-step. Think of it like a series of filters on a camera lens—each one shapes the final image. In audio, placing the right filter at the right point ensures clean, balanced sound. For example, if you put the compressor before the gate, background noise might get squeezed through during quiet moments. Conversely, putting the gate first keeps unwanted sounds out of the chain entirely.
Applying filters in the wrong order can cause issues like unnatural sound or unintended artifacts. So, understanding the flow helps you craft a sound that’s clear, balanced, and professional.

The Proven Filter Chain: Gate, then Compressor, then Limiter
The most common and effective filter chain for streaming and recording is Gate → Compressor → Limiter. Here’s why:
- Gate first: Cuts out background noise and unwanted sounds when you’re silent. Think of it as a noise shield that prevents your mic from picking up room sounds or keyboard clicks during pauses.
- Compressor second: Balances your volume, making quiet parts louder and loud parts softer. It keeps your voice steady—imagine speaking into a mic that smooths out your natural fluctuations.
- Limiter last: Acts like a safety valve to prevent sudden loud peaks from distorting or clipping. It’s the final guardrail, catching those unexpected loud outbursts—like a cough or a quick shout.
For example, during a live gaming stream, this chain helps keep your voice clear and consistent, even when you get excited or cough unexpectedly.

How Each Filter Shapes Your Sound — Real World Examples
Imagine you’re streaming from a noisy room with a fan humming in the background. Without the right order, your microphone might pick up that hum even during quiet moments. Placing a gate first cuts out the fan noise when you stop speaking. Next, a compressor evens out your voice volume—so whispering and shouting sound consistent. Finally, a limiter caps your loudest sounds, avoiding distortion if you get excited or accidentally shout.
Another scenario: during a podcast session, your voice fluctuates naturally. The compressor ensures your soft-spoken parts don’t get lost, while the limiter prevents sudden loud outbursts from causing distortion. This setup makes your audio feel balanced and polished.

Quick Guide: Setting Up Your Filters in OBS
- Open your OBS audio mixer and click the gear icon next to your microphone.
- Select ‘Filters’ from the menu.
- Add a Noise Gate: Set thresholds just above your background noise—start with -30dB to -40dB.
- Add a Compressor: Use a ratio around 4:1, attack about 10ms, release 100ms, and adjust threshold so your voice is balanced.
- Add a Limiter: Set at -1dB or -0.5dB to catch peaks without sounding squashed.
Always monitor your audio and tweak these settings based on real-world tests. Your voice, environment, and equipment vary, so don’t rely solely on presets.

Common Mistakes & How to Avoid Them
Many streamers accidentally put the compressor before the gate, causing background noise to get squished during quiet moments. Others overdo the limiter, making their voice sound compressed and unnatural.
To avoid this, always test your setup with real speech. Use OBS’s monitoring feature to listen in real-time. Adjust thresholds gradually—small tweaks make big differences. Remember, less is more: heavy filtering can lead to artifacts or a robotic sound.
For example, a streamer once set their compressor too high, causing their voice to pump and breathe unnaturally. By reversing the order and dialing down the compression, they achieved a more natural sound.
Extra Tips for Peak Performance
- Always test your settings in a real streaming scenario before going live.
- Use headphones with good isolation to catch artifacts or unnatural sounds.
- Adjust thresholds based on your environment—no one-size-fits-all.
- Consider adding a high-pass filter to remove rumble or low-frequency noise.
Remember, your goal is transparency—your audience should hear your voice clearly, not the processing.
Frequently Asked Questions
Should I put the compressor before or after the gate?
Always put the gate first. This way, background noise stays out of the compression, keeping your sound clean during silent moments.How do I know if my filter settings are too aggressive?
If your voice sounds squashed, robotic, or you hear pumping effects, reduce compression ratios or raise thresholds. Use headphones to listen carefully.Can I skip the limiter?
While optional, the limiter is highly recommended. It prevents unexpected peaks from clipping or causing distortion, especially during loud moments.What if I hear distortion after adding filters?
Check your limiter and compressor settings. Too much gain reduction or limiting can cause distortion. Dial back the thresholds and monitor the changes.Is there a perfect filter order for music or gaming sounds?
Not necessarily. For music, you might prioritize EQ and reverb. For game sounds, filters are often minimal. But for voice, the Gate → Compressor → Limiter order remains best.Conclusion
Getting your OBS filter order right is a game-changer. A simple sequence—Gate, then Compressor, then Limiter—can turn a noisy mess into broadcast-quality sound. It’s not magic, just good listening and smart setup.
So, set up your chain, tweak those thresholds, and listen. Your audience will thank you for it—and your voice will sound clearer, smoother, and more professional with less effort.
