For the sound i would like to create like an "extraterrestrial signal", i took a "sifflet" and i play with it, add opening and closing effect, reverse the sens and finish the set with a battery sound to put a bit of "suspens". . .
Sound design that i made for a video game,layered a bunch of sounds and processed them to create an impactful sci-fi sound. This one is a spaceship door opening.
A broken space heater that clicks. Recorded with a zoom h5 using the onboard xyh-5 capsule to capture a stereo signal and a sennheiser k6/me66 for a mono track. Very minor post processing to balance the stereo/mono and pull the subs out of the side channels.
