Grey-equalized noise at 3.9 with a 25-second swell, life support in the next module

Space Station is the constant hum of machinery keeping a sealed environment alive: deep, even, and slowly breathing as pumps and fans cycle somewhere out of sight. It is darker than Airplane Cabin and its slow swell gives it a sense of vast, patient systems running around you.
The color is 3.9, nearly brown, with grey EQ on to keep the bass from turning to mud. A sine pulse at 0.04 Hz raises and lowers the level once every 25 seconds, slow enough to feel like the ventilation cycling rather than a rhythm. The fade-in is five seconds.
It is picked for sleep and for people who like a science-fiction feel to their background sound. Submarine is a close cousin with an envelope loop instead of a pulse, and Spaceship Hull in the textured category adds comb and resonant filters for a metallic ring.
