In my company, we have paper shredder. It's located on the hallway some 10 meters from my office. For a last few weeks now, machine is making really creeping noise when somebody puts paper for shredding (probably it needs to lubricate). Since we have open doors in our office it's really anoying to listen that sound. Actually it's so anoying, that today I got idea to use it as a sound for morning alarm :). Here it's possible to download it:
the truth is that when I recorded this, shredder stopped to be in it's best shape, so recording is not so good enough as I would be expected. I hope that in some near future good old sound will return, so I could upload better file.
