MicBeam

Stream your mic from one PC to another over the network. No cloud. No accounts. No bullshit.

Typical setup: any PC Send Mic → your main PC Receive, piping into VB-CABLE so Discord, OBS, games, whatever just sees it as a normal microphone.

It remembers your last peer, mode, devices, and format, so it just reconnects on launch instead of making you set it up every time.

Install

https://github.com/litruv/micbeam/releases

• Windows - unzip, run CrossPlatformMicStreamer.exe. Allow on Windows Firewall if it asks.
• Linux - chmod +x MicBeam-x86_64.AppImage && ./MicBeam-x86_64.AppImage (you may need libfuse2 depending on distro)
  • use something like AppImageLauncher to make it easier to launch later
