sfxr's original purpose was to provide a simple means of getting basic sound effects into a game for those people who were working hard to get their entries done for the Ludum Dare gaming contest within the 48 hours and didn't have time to spend looking for suitable ways of doing this. The idea was that they could just hit a few buttons in this application and get some largely randomized effects that were custom in the sense that the user could accept/reject each proposed sound.
