How do I keep an application window hidden when not accessed?

Question

I have an application running constantly to control my FW audio interface outputs etc. I use system events applescripts to control it's UI with a USB controller (PowerMate) - and that by necessity brings the application window to the front every time accessed. That's fine.
But I want to have a script that hides this application window when it's not used after 2 seconds. Maybe there is an "on idle" script that could run to check if that window is visible. I imagine something including lines like this:
-- a routine that checks if the window is visible every 2 seconds or so.
-- the window reference
window "Studio Monitor Express" of application process "Studio Monitor Express"
-- if it is, then hide it
-- for hiding the window/app
keystroke "h" using command down
-- if it's not, then ignore
I'm not sure whether to use system events or finder events etc. I have a bunch of other apps running obviously, but I just want this particular window to disappear when not needed.

Answer 1

I solved it. I know. Easy:
on idle
tell application "System Events"
set visible of process "Studio Monitor Express" to false
end tell
return 2
end idle
