A rough analog to an explosion, a work in progress, could be coupled with sounds of trash and debris to make the sound fuller. May fit as an artillery sound effect.
This is a piece, which is a continuous sound, realized a couple of decades ago, with an arp 2600 analog synthesizer. The idea was to create a kind of "tornado" sound.
Ambient recording of an underground parking lot at midday near the entrance to the parking lot. A couple of janitors can be heard speaking in the background. Cars passing far away. An open water pipe draining into a sewer a couple of meters away.
Here's some more of that couple next door. At 0. 24 sounds like a door close, so consider that's when the couple begins to have their you know in bed. Passed 1:05 is where you can start hearing a bit of the woman. Passed 1:55 is where the woman gives out some louder moans. The sex noises is from 1:05-4:37. This was edit and shorten with audacity.
