I started recording about 11:59 PM, December 31st, 2010 and stopped just before 12:20 AM on January 1st, 2011, using only my Sony PCM-D50 digital recorder. The recorder was on a tripod facing out of the sliding glass door which opens out to my deck. I kept the door open during the recording and with the outside temperature possibly below 25 degrees Fahrenheit, the cold air rushing in caused a lot of creaking as the furniture and other items inside my living room began to make contact with the cold air. The occasional snapping and popping noises are sounds that the table and chairs made as cold air rushed into the room. I believe the door frame made some noises, as well.
