It's synthetic material. I had, first of all, want to realize noises of gulls. But as one goes along, my approach in changed and this spirit of submarine spaceship came to me.
To arrive at this result I generated a sound of 1000hz then in the course of its reading I varied it with 200hz. Afterward I slowed down at the most the speed, used just a little of réverb. Cut the sound in two to play with the overlapping. I then changed the tempo both so that two different noises get on. To end I added some echo.
