Arduino and Sounds

Trying to think how me and Kathleen can incorporate an Arduino board into our project I came up with the idea of maybe hacking a Sound Level recorder and attaching it to an Arduino board, possibly analogue as this will give us a more natural read out instead of just digital 1's and 0's. The read out that we get can then be Incorporated into our flash files as a way of determining how much of the building would be eroded this I hope would give us the desired effects.

So now to buy a few things and to get started, back to the good old days of electronics.
