This is a homemade space engine sound to accompany a large space craft. It is my mouth making a rumbling sound, a little distortion, and a little chorus effect.
Lewis carroll wrote down a wonderful russian word while he was visited russia: "защищающихся" it will make you froze with horror: zаshtshееshtshауоуshtshееkhsуа.
Made this sound in audacity in around 5 minutes. Tried to make a sound for my game, but found that this could be useful in other games. Maybe a powerup?.
