A stack beeep sound. It was created with me accidentally breaking my microphone. . . Here you go. This is in the public domain so do absolutely anything you want with it. What am i going to do, sue you?.
This is what it sounds like on a computer’s fan, i manually clicked it on maximum speed for 30 seconds straight, recorded and edited on a iphone 13 pro device. Yes this is a laptop if you already know in the tags.
