How to Set Up a Microphone for Streaming on Twitch or YouTube? (Basic Settings)

Introduction

Audio is half the success of any stream. Even with excellent video quality, viewers will quickly leave if the microphone hisses, buzzes, or sounds too quiet. In this article, you'll learn how to set up a microphone for streaming on Twitch and YouTube using OBS Studio and Windows, so your voice sounds clear and professional.

Quick Solution

1. Check your microphone on DoCam.io.
   Make sure the device works and the signal level is stable.
2. Select the correct audio source in OBS.
   Settings → Audio → Mic/Auxiliary Audio.
3. Add filters: Noise Suppression, Noise Gate, and Compressor.
   This removes background noise and levels volume.
4. Adjust the volume level.
   The level should reach -6 dB during speech.

Detailed Guide

1. Checking the Microphone in Windows

1️⃣ Open Start → Settings → System → Sound → Input.
2️⃣ Select your microphone and say a few words — the indicator should move.
3️⃣ If needed, increase the volume to 90%.

Tip: Before launching OBS, make sure the sound isn't being automatically amplified by system tools.

2. Setting Up Microphone in OBS Studio

1️⃣ In OBS, open Settings → Audio.
2️⃣ In the Mic/Auxiliary Audio section, select the desired device.
3️⃣ Add Source → Audio Input Capture (if not already added).

3. Testing Audio

Before streaming, make a short recording in OBS:

1. Click Start Recording.
2. Talk for 20–30 seconds.
3. Listen to the recording — audio should be clean, without clipping.

If the voice sounds muffled — add some high frequencies in the equalizer (through the VST plugin EQ filter).

4. Setting Up Discord or Voice Chat

If you're using Discord alongside OBS:

• In Discord → Settings → Voice & Video → disable "Automatically determine input sensitivity".
• Enable noise suppression (Krisp).

5. Check Volume and Echo

Avoid sound from speakers — use headphones only. Check that "Listen to this device" isn't enabled in Windows microphone properties.

Error: echo or double sound
Solution: disable "Listen to this device"

Tips for Streamers

• Keep the microphone 15–20 cm from your mouth.
• Use a pop filter for smoother sound.
• Check your microphone before every stream on DoCam.io.
• Don't raise the boost above +10 dB — noise will appear.

Conclusion

Congratulations! You've set up your microphone for streaming on Twitch or YouTube. Now your voice sounds professional and stable, without background noise or clipping. Check quality regularly before broadcasts — and your viewers will appreciate it!

Before going live, test your microphone on DoCam.io.
