Improve Mic Quality in Streamlabs Desktop

This guide walks you through improving your microphone audio quality inside Streamlabs Desktop, covering filters, settings, and placement tips. You’ll learn how to reduce background noise, eliminate clipping, and make your voice sound clearer for your streams.

What You’ll Need

• Streamlabs Desktop installed (latest version recommended)
• A microphone connected and recognized by your computer
• Headphones (to avoid feedback and monitor your audio properly)
• Basic knowledge of your microphone’s model and connection type (USB or XLR)

Step-by-Step

1. Open Streamlabs Desktop and go to Settings. Click the gear icon in the bottom-left corner, then select Audio from the left sidebar.
2. Select your microphone. Under Mic/Auxiliary Device, choose your actual microphone from the dropdown. If you’re using a USB mic, it usually appears with its brand name. For XLR mics, select your audio interface.
3. Set the correct sample rate. In the same Audio settings, set Sample Rate to 48 kHz (or the rate your mic/interface supports natively). This avoids resampling issues that can degrade quality.
4. Adjust the input volume. Speak at your normal streaming volume and watch the meter next to Mic/Auxiliary Device. Aim for peaks around -12 dB to -6 dB (green/yellow zone, not red). Adjust the slider until you hit that range.
5. Enable and configure filters. Click the Filters button (the gear icon) next to your microphone in the Audio Mixer. This opens the Filters panel.
6. Add a Noise Suppression filter. Click the + button, choose Noise Suppression, and name it (e.g., “Noise Suppression”). In the settings, choose RNNoise (default) or Speex if you need more aggressive suppression. Keep the strength moderate (around -30 dB) to avoid a robotic sound.
7. Add a Noise Gate filter. Click + again, select Noise Gate. Set Close Threshold to about -50 dB and Open Threshold to about -40 dB. This mutes the mic when you’re not speaking, cutting out keyboard clicks and room tone.
8. Add a Compressor filter. Add a Compressor filter. Set Ratio to 3:1 or 4:1, Threshold to about -18 dB, and Attack to 10 ms, Release to 100 ms. This evens out volume spikes and makes your voice more consistent.
9. Add a Limiter (optional but recommended). Add a Limiter filter. Set Threshold to -3 dB and Release to 100 ms. This prevents clipping when you get excited and speak louder.
10. Add an EQ (optional). If your mic sounds muddy or harsh, add a 3-Band EQ filter. Boost the mid band slightly (+2 dB) for clarity, and cut the low band if you hear rumble.
11. Test and tweak. Speak into the mic and watch the levels. Make sure the noise gate isn’t cutting off the start of your words. Adjust thresholds if needed.
12. Monitor with headphones. In the Audio settings, enable Monitor & Output for your mic (or use the headphone icon in the mixer). Listen for any artifacts and re-adjust filters.

Common Mistakes

• Too much noise suppression: Over-suppressing can make your voice sound like it’s underwater or robotic. Use the minimum amount needed.
• Gate set too high: If the open threshold is too high, the gate won’t open when you start speaking, cutting off your first words.
• Mic gain too high: If your input volume is in the red, you’re clipping. Lower it and use a compressor/limiter instead.
• Applying filters to the wrong source: Make sure you add filters to the microphone source, not the desktop audio or a scene.
• Skipping the sample rate: Mismatched sample rates between the mic and Streamlabs can cause pitch shifts or crackles.

Tips

• Physical placement matters: Keep the mic 4-6 inches from your mouth, slightly off to the side to avoid plosives (popping sounds). Use a pop filter.
• Treat your room: Soft furnishings, curtains, and rugs absorb echo. Even a blanket over a chair behind you can help.
• Use a dynamic mic if you have a noisy room: Dynamic mics are less sensitive to background noise than condenser mics.
• Update your audio drivers: Outdated drivers can cause crackling or low volume. Check your motherboard or interface manufacturer’s site.
• Record a test clip: Use Streamlabs’ recording feature to listen back. Your ears are the best judge.

Troubleshooting

• No sound at all: Check that the correct mic is selected in Windows sound settings (right-click speaker icon → Sounds → Recording). Ensure Streamlabs is using the same device.
• Mic sounds quiet: Increase the input volume in Streamlabs, but also check the Windows microphone level (Properties → Levels) – it should be at 100. Then adjust Streamlabs.
• Crackling or static: This often comes from USB ports. Try a different USB port, preferably directly on the motherboard. Also check for interference from other USB devices.
• Echo in the stream: If you’re using speakers, switch to headphones. Also ensure your stream isn’t picking up your own audio output – disable Desktop Audio monitoring if needed.
• Filters not working: Make sure the filters are applied to the correct source. In the Filters panel, check the source name at the top. Also, restart Streamlabs after adding filters.
• Voice sounds robotic: Reduce noise suppression strength, or switch from RNNoise to Speex with a lower cutoff. Also check that your internet upload speed is sufficient for your bitrate.

Frequently Asked Questions

Do I need a compressor if I have a limiter?

Yes, they work differently. A compressor evens out the overall volume, while a limiter only catches peaks to prevent clipping. Both are useful.

What’s the best noise suppression method?

RNNoise is generally better for voice and less CPU-intensive, but Speex can be more aggressive. Try both and pick what sounds best.

Can I use these filters for Discord or other apps?

No, these filters only work inside Streamlabs. For other apps, you’d need separate software like VoiceMeeter or the app’s own settings.

Why does my mic sound fine in Windows but bad in Streamlabs?

Check that the sample rate matches, and that you haven’t accidentally enabled a filter that’s too aggressive. Also, make sure the input volume isn’t maxed out.

Should I use a noise gate if I have noise suppression?

Yes, they complement each other. Noise suppression reduces constant background hum, while the gate cuts out sudden noises when you’re not talking.

How do I know if my mic is clipping?

If the meter in Streamlabs hits the red (0 dB) and the audio sounds distorted, you’re clipping. Lower the input volume or add a limiter.
