How can I use my sound-enabled webcam as a microphone?

I recently bought a new Dell Inspiron, and it has a nifty little built-in webcam that also captures sound quite well. Is there any way to isolate this function in order to, say, record directly to Audacity?

Sorry for the computer-related question, but it didn’t seem to be one of the no-nos in the sticky.

Sorry, I’m a huge dumbass. Of course I downloaded Audacity just now, clicked record, and it knew exactly what I was trying to do. Feel free to close this thread, mods.
