I've recorded some rubber mats rubbing against a tabletop in my kitchen. At times it sounds like a car skidding. Recorded with zoom h2 at 96khz/24-bit. Converted to flac with audacity. Making of: https://youtu. Be/3qwqjmja4gy.
This is a bunch of sounds from bending and moving soft equipment. It was used to create audio for the movement of some geared-up police operators in a game.
This sound is a recording of an annoying chair friction. It was recorded using a zoom h4 recording device at the upf campus in the 003 aula from tallers. The recording was edited with a fade in and a fade out effect.
This is a continuous sound (low frequency) of the wind and the friction of it with the microphone. It's recorded inside of the playground at upf campus of poblenou, barcelona. It was recorded at 13:20. Recorded using zoom h4, normalized with audacity and adde fade-in and fade-out.
Generated sound as sinusoid 852hz - 0,8db for 0,5si modified the curve of the sound at the beginning and at end. I suppressed the unmodified part of the sound and i decrease the speed gettin' us some kind of friction.
