This is the standard startup sound with a voice saying "Slide" at the end. I use it with my splashscreen (http://www.kde-look.org/content/show.php?content=7044) because it makes the whole thing feel Fight Clubish. If you don't know what I mean go watch Fight Club, look at the splashscreen and then listen to the sound. It'll all come together...Sorry it's a .zip file, I'm on Windows right now, I'll make it a .tar later.
Feel free to use, edit or do with it as you please. You can even claim it as your own. But please comment, good or bad on what you think of it.
