Do you remember that good old Microsoft Messenger sound? Or that sound your computer made when it was starting up back in the ’90s? Will your children know what a dial-up modem sounded like?

If you’re into creating weird sounds, however, check out another virtual database, The Online Museum Of Weird Instruments.
