Recorded a door closing at my school and then modified it in audacity to create a sort of sproing-ing sound. Use: when you need a boomerang sound that isn't really a boomerang but that's ok because it sounds like one.
I created these clicks as the ones that come stock in daws can be quite nervewrecking. For this i used the steinberg retrologue, soundtoys devilloc and a lot of filtering and eqing.
