Ok, I have way to many audio files on my computer. Over 10,000 to be exact. No, I'm not that prolific. Many are included with applications, left over from web browsing, etc. To find a way to deal with this before clearing space on the hard-drive, I decided to pick a few random sounds and post them above. Make new audio. (what?) Can you guess where they came from? Tell me which ones you like best...
