I like using this one http://www.trekcore.com/audio/cloaking/c...omulan.mp3
If any Star Trek lovers want to replace some sounds, here's the page I am using http://www.trekcore.com/audio/.
I'm also using the Red Alert sound on some of the other things. Also, I wonder if you can change the "charge engine" when you press cruise engines with the Warp engines sounds.
