Microphone input

I am trying to store an input sound wave on the DE2 board as a digital signal that I can analyze and make calculations with. Does anyone have any suggestions on how to do this? Thanks

A basic building block for your design is the audio codec interface, it can be copied from the DE-2 demonstrations. You can process the data stream in realtime or store it to embedded or external memory for further processing.
