This emulates the ambient noise of a planet sized computer and its associated gargantuan processes. I aimed for a "what if" scenario. What if v'ger could speak to other similar artificial entities of enormous size and complexity. Originally recorded on zoom h2. The sound was originally a styrofoam take-out container which i pressed down on and released several times. I then filtered it.
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.
