I was just messing around in Audacity, like I usually do all the time. I made a corrupt audio file, and I found this extremely weird sound. I got rid of all the white noise, which made it sound even weirder, then I slowed it down and got this sound. You can use this however you want. I'm not sure what it's even meant for, like something being activated, robot beeping, etc. Enjoy. :)
