Professional Audio Processing
Master audio processing for crystal-clear streaming
Audio is one of the most important parts of your stream, even more than video. Viewers can forgive a drop in framerate, but they won't stick around if your voice sounds muddy, distorted, or too quiet. Audio processing makes sure your voice is clean, clear, and consistent, this will help you sound like a true broadcaster.
This guide covers software and hardware-based audio processing, plugins, routing tools, and best practices used by pro-level streamers and content creators.
What Is Audio Processing?
Audio processing refers to the use of filters and effects to improve and control your microphone signal. Common processes include:
- Noise Gate: Mutes mic when you're not speaking
- Compressor: Evens out loud and quiet sounds
- EQ (Equalizer): Shapes your voice tone
- Limiter: Prevents audio from clipping or peaking
- De-Esser: Softens harsh "S" sounds
These tools can be stacked using plugins inside OBS, Voicemeeter, VST hosts, or hardware mixers.
Software Tools for Processing
OBS VST Plugins
OBS Studio allows you to load VST2 plugins directly into your mic source.
Recommended Free VSTs:
- ReaPlugs (REAPER VST Suite)
- ReaEQ, ReaGate, ReaComp, ReaLimit
Voicemeeter Banana or Potato
- Virtual mixing console for routing and processing
- Built-in compressor, gate, EQ, and more
- Route multiple mic and system inputs independently
Wave Link (for Elgato users)
- Real-time mic control with stream/monitor routing
- Supports VST plugins through OBS
Hardware-Based Audio Processing
GoXLR / GoXLR Mini
- Built-in hardware compressor, gate, EQ
- Fader control and routing matrix
- No PC CPU load
Preamp/Audio Interfaces
- Elgato Wave XLR, Focusrite Scarlett, or Rode Rodecaster Pro are perfect for stepping into more advanced audio
- Clean signal, phantom power for XLR mics
- Can be paired with VST or hardware rack processors
Recommended Processing Chain Order
- 1Noise Gate – Silence unwanted background noise
- 2EQ – Clean up rumble and enhance vocal tone
- 3Compressor – Level out volume for clarity
- 4De-Esser – Soften harsh "s" sounds
- 5Limiter – Prevent peak distortion
Use Studio headphones to properly monitor how each effect changes your audio.
Pro Tips
- Use low-cut filters to remove bass rumble (start around 80–100Hz)
- Don't overcompress—aim for subtle control, not distortion
- Monitor your levels live with headphones to avoid mic bleed or clipping
- Test your setup with a recording session before going live
