While I was researching Ash Dargan's record label, I found a very cool, online music creation tool that let's you create various didj sounds through your computer. There is no direct link (that I can find) but here's how to get to this didj sound generator:
Here's the link for Indigenous Australia: http://www.indig.com/
Click on "Cool Stuff" link from the navigation bar at the top of the website
Then, click "Virtual Corroboree"
Play around with the various button and have fun!! See if you can jam along with the flute.
