I used the sound of a brush scraping as the source, added the sound you get when you twist a russian doll (already convolved with itself), and this was the result. To me it sounds a little bit like wind.
Polar wind sound made with mouth blowing into hollow objects. Projet “bruitages” coordonné par josé carrasco, classe de jérôme euphrosine au lycée français de barcelone, hiver 2013.
A fan blowing, set to the highest setting. There's a strong low end presence, interestingly. The recording was made from behind the fan so the air wouldn't blow into the mic directly. Recorded with a zoom h1.
A standing bicycle pump with the normal fitting was used to produce the sound. A zoom h6 recorder, using the xy capsule was used to record the sound inside a garage.
