This is a modified version of "earthkiller background 1", the background noise inside a space station. I removed some upper midrange (1700 hz) to make it easier to mix with dialog.
The sound of an engine winding up and then winding down (with a sci-fi feel). It's actually a small plastic ball being spun around the inside of a balloon. . . Recorded with zoom h4n.
Very brief sound effect, yet another attempt at making an "astroboy"-style sound effect - kind of like a character in a film being instantly zapped from one place to another.
