+description: "NVIDIA Broadcast control through its local MCP gateway: camera, microphone and speaker
+  effects, Studio Voice profiles, device selection, camera resolution, and effects on local media files.
+  Requires NVIDIA Broadcast 2.3 or newer on Windows (2.2 and older have no gateway); the install is
+  refused when the app is absent, and the tools appear while NVIDIA Broadcast is running in the user's
+  desktop session. Disclosure: the tools change live audio and video effects on this machine; nothing
+  leaves loopback."
