How to Make Your Budget Mic Sound PRO in OBS Studio ✅
A companion walkthrough to follow alongside the written guide.

- 01
Record a baseline
Select your USB microphone in OBS and wear headphones. Make a short recording with filters disabled: include a pause, normal speech and a louder sentence. Save it as your before sample. Listen for the main problem—room noise, echo, plosives or uneven volume—so you can judge whether each change helps.
- 02
Improve the sound at the microphone
Check which side of the microphone you should speak into; some accept sound from the side, others from the end. Start about 10–15 cm away and slightly off to one side to soften breath blasts. Move a noisy fan away, reduce bare-room reflections and keep the mic off a vibrating desk where possible. Adjust distance to suit your microphone.
- 03
Leave room for louder speech
Adjust the mic gain while speaking at your real recording volume. As a starting target, let normal speech peak around −12 to −6 dBFS in OBS, leaving space below 0 dBFS for louder moments. Record and listen again. Lower the device gain if the signal distorts; an OBS filter cannot repair clipping that already happened at the microphone.
- 04
Reduce steady noise only if needed
Open the microphone mixer menu and choose Filters. Add Noise Suppression and try RNNoise if available. Compare a short sample with the filter on and off. Keep it only if noise improves without making your voice watery or robotic. A quiet room may need no suppression at all.
- 05
Soften noise between phrases
If pauses are still distracting, add an Expander. Start with its Expander preset and adjust the threshold while alternating silence and quiet speech. Lower the threshold if word endings disappear. Keep this optional filter before the compressor so compression does not make the background harder to separate from your voice.
- 06
Even out louder moments
Add a Compressor after the expander, if used. Try a gentle 3:1 ratio with 0 dB output gain, then lower the threshold until louder phrases are controlled without flattening every sentence. Leave attack and release at their defaults initially. Add a Limiter last, around −3 dB, as a final ceiling rather than a way to make everything louder.
- 07
Compare at the same listening volume
Repeat your baseline script, including quiet words, a loud sentence and keyboard use. Compare before and after at a similar playback volume: louder alone does not mean better. Disable any filter that does not help. Save your working setup, then make a short test with game sound to check that commentary stays understandable.
Check your finished work
Use this checklist before moving on.
Something not working?
The voice sounds robotic or muffled
- Disable Noise Suppression and compare the same sentence.
- Reduce room noise and improve mic placement before trying stronger processing.
- Bypass filters one at a time to identify which one changes the voice.
The start or end of a word disappears
- Lower the Expander threshold or disable it.
- Test with your quietest intended speech, not just a loud test sentence.
The recording echoes or plays only on one side
- Use headphones and make sure the microphone is not captured twice.
- For a mono microphone recorded on one channel, open Advanced Audio Properties and enable the mono option for that source.
The microphone still distorts with a limiter
- Lower the physical or operating-system input gain. The signal may be clipping before it reaches the limiter.
- Move slightly farther away for very loud commentary and record another test.
