I'm wondering if any of you guys have any tips or tricks for creating realistic ambiences from scratch, i.e. without using any pre-recorded material.
I'm working on a radio drama set in a lunar space station, so it's going to be all air-filtration systems, computer hums, and spaceships flying around. Very tight, very close. I have a bunch of great recordings of air-conditioners and small generators and stuff that I've been collecting over the last few months, but I'd like to see if I can build all of it using analog synths and the signal generator in PT. I'm going for a style similar to Space Force, X Minus-1, Hitchhiker's Guide to the Galaxy, and Journey Into Space, so I thought I'd try and emulate their way of producing atmospheres for the scenes.
I've got a few going already, but wanted to see if you guys had any experience doing this, or had made any cool discoveries as to how to put stuff together. My biggest concern is figuring out how to get things like power-generators and computer banks to sit in a space in a realistic way.
Other than that, anything weird and wacky that'll add a bit of texture and motion is more than welcome as well.
