Audio Routing with Voicemeeter

Build a cleaner, more flexible audio setup for streams, recordings, and dual-PC workflows.

As your production gets more advanced, clean audio routing matters just as much as video quality. Voicemeeter acts like a virtual mixer, giving you better control over game sound, microphone input, alerts, Discord, music, and anything else in your setup.

What You'll Need

Software

  • Voicemeeter Banana or Potato
  • VB-Audio Cable (included or optional for extra virtual channels)
  • OBS Studio or Streamlabs Desktop

Hardware

  • Microphone (USB or XLR with audio interface)
  • Headphones (for monitoring)
  • Dual PC setup (optional but supported)

Setup Breakdown

Install Voicemeeter and Set It as Default

  • After installing Voicemeeter and restarting your PC, open:
  • Sound Settings > Playback > Set Voicemeeter Input as default device
  • For recording, set Voicemeeter Output as your default microphone/input.

Route Physical Inputs

  • Assign your microphone to Hardware Input 1.
  • Assign additional devices like USB mics, instruments, or line-ins to Hardware Input 2 or 3.
  • Dial in gain and noise gate settings so your voice stays clear without clipping.

Route Virtual Inputs

  • Voicemeeter includes two virtual inputs: Voicemeeter VAIO and AUX.
  • Use these to control:
  • Game Audio → VAIO
  • Music (Spotify, etc.) → AUX
  • Discord Chat or Zoom → Optional extra VB-Cable

Send Audio to Outputs

  • Use the A1–A5 buttons to send any input to physical outputs like headphones or speakers.
  • Use B1–B3 buttons to send audio to virtual outputs that OBS can capture.

OBS Configuration

  • In OBS, set your Mic/Aux input to Voicemeeter Output (B1) or Voicemeeter AUX Output (B2), depending on your routing setup.
  • Mute OBS desktop audio if you're routing it through Voicemeeter instead.

Example Use Case: Dual PC Streaming

  • Your gaming PC runs Voicemeeter and manages game audio, Discord, and microphone routing.
  • That mix is sent through Voicemeeter Output → NDI or a physical cable → your streaming PC.
  • On the streaming PC, capture that audio source in OBS with a virtual cable or line-in input.

Advanced Tips

  • Use EQ and Compressor inside Voicemeeter to polish your mic before it reaches OBS.
  • Use VBAN (Voicemeeter Network Audio Protocol) to send audio wirelessly to another PC over LAN.
  • Create separate audio mixes so your audience hears one version while you monitor another.
