The WCS-999 is monoaural. http://www.sonystyle.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10551&storeId=10151&langId=-1&partNumber=WCS999&Dept=cameras
Microphones have one element and thus are monoaural. You can get a microphone package with two elements for stereo audio, but why would you do this?
