WebGizmos is right..Sounds are generic really..and so very easy to change..
Heres a great "Sound Recorder" program that I used to use to capture sound bits for web pages I used to create.. http://www.highcriteria.com It will capture anything going through your sound card, it's a great little program...
You can save the files to MP3, and make them as long or as short as you want... For editing I use a program called "GoldWaV" but thats getting a bit more involved..
Anyway,
Enjoy,
Zero.
