A power up sound for any sort of mechanical, high tech, or sci-fi charging up sound. Can also work for turning on jets and turbofans. This was recorded by a tascam dr-05 and is a printer cooling down reversed.
Roller coaster clanking up track in distance. Metal clank as it is pulled up. Shuddering and roar of car as it runs. Some voices talking from the ground. Some wheel squeak and a "woo!" towards the end.
Moka-pot gurgling as it fills up with freshly-made coffee. Close-up recording as i brought the lid down (perceivable lowpass effect on the coffee noise), using the voice notes app on my smartphone.
I sound recorded my metal slinky springing up and down as i was holding it. If you put your recorder on the slinky you should end up hearing the following sound, like an armada of storm troopers.
