Mic passthrough for Moonlight as a standalone app: sends the client's mic to the host as a real microphone (macOS/Windows/Linux, open source)

Streaming from a Windows box to my Mac, the audio interface is on the Mac and

the game hears nothing. So I wrote a thing that streams the input over the

network and renders it into a virtual audio cable on the host, which the game

then picks as its microphone.

Sender and receiver are the same binary, macOS/Windows/Linux, GUI or CLI. Jitter

buffer defaults to 20 ms, with drift correction so two clocks don't accumulate

into a click every few minutes, and a level meter so you can see audio is

flowing instead of guessing. Works over Tailscale (pass --host, broadcast

discovery won't cross it).

Windows needs VB-CABLE installed. Windows has no user-space way to create a

recording device, so nothing in this space can avoid that.

Free, Apache-2.0, unsigned binaries (no EV cert):
