Your selection is remembered per device and restored when it comes back.
Quiet in the tray.
Closing the window keeps it running. A global hotkey turns every mirror on or off.

Audio Mirror plays sound like any other program, so a recorder may pick it up too. What we measured:
Capturing a device
OBS "Desktop Audio" records one device. The mirror plays on a different one and never shows up.
Capturing all applications
Discord screen share with desktop audio catches the mirror as well. Audio arrives twice and voice chat echoes back.
- Capture a device or a specific app, not "all applications".
- Untick voice apps like Discord or TeamSpeak for the mirrored device.
Free and open source.
Needs Windows 11, or Windows 10 build 20348 and later. Runs on x64 and ARM64.
