There's a sound effect I've heard every now and again, mostly in videogames. I really like the sound of it and want a nice sample of it for potential future projects, and I'm reasonably sure that it's a stock effect of some kind since it's been re-used so often, but not only do I have no idea how to search a library for the noise, since it doesn't specifically sound like much of anything, I also don't have any idea where to start on recreating it myself.
