I'm working on a sci fi short film right now. One of the major elements in the film is a machine that keeps people from dying. Upon death, the soul leaves the body, stays in a "test" room, and the machine sucks it back into the person, preventing death.
The main mechanical function of the machine is to power large underground rotors that generate the energy needed to keep the soul from entering the gates of heaven or hell (depends if you're good or bad!) It powers up, releases an energy burst, then powers down.
So far, I have a combination of my own recordings/ signal generator fx and library effects. It's sounding kind of generic right now due to the amount of library effects, and I'm looking for things to record to enhance or replace what I have now.
Does anyone have any suggestions on what I can record for the power up sequence? I live in Los Angeles.
