Yes, thanks! It was a bit complicated to create mono ogg-files but now thanks to the great Audacity it finally worked!
I'm making this Battlestations-sound mod, at least now for my own use, but if it works well I could upload it somewhere for others too.
The point is to simply change the two on/off Hud-clicks to atmospheric sound clips. So if you activate any ability (silent running, special meal, battle stations, man the flak guns and so on...) no more clicks, but a nice variety of alerted shoutings, footsteps, and orders. And when ability is expired or turned off, different sound clip will start (more relaxed, telling that situation is over).
It will also add extra sounds to the shortcut ability keys, like massive Alarm! -shout when battle stations are called (F7). The bad thing is that I don't know how to make off-sounds to the shortcuts! So the same sound will begin again. It doesn't matter with most of the skills (their sounds are netraul) but with Alarm! it's bit annoying. The only solution is to tell Executive Officer to disable battle stations manually. This might not be for everyone, but I like it already!
