There are various audio shields out there, some of which have recording capabilities. For example, the Rugged Audio Shield. I don't own this, but I have thought about getting it. https://shop.ruggedcircuits.com/index.php?main_page=product_info&cPath=1&products_id=58
If quality is not important, and you just want 10 seconds or so, this might work for you (I got this to add a sound effect to a prop, but I haven't done much than just record one sound and play it back): http://www.ebay.com/itm/300670071550?ssPageName=STRK:MESINDXX:IT&_trksid=p3984.m1436.l2649
