ARTFX-Studios owner Kaj van den Oord sampled some odd things during a recording session: sounds of zippers, metal, skateboard wheels. He edited the samples, added some cool sound effects and sorted them in 12 categories.
The resulting 480 audio samples and loops are bundled in the package ARTFX Sound Effects Volume 1 and available for free via the ARTFX-Studios website. On the site you can also listen to some interesting music by Kai van Oord.
