I used a binaural microphone to record the rain hitting my umbrella. You will need to use headphones for the "3D" audio effect to work. Also, it helps if you select HD quality. Sorry about the random planes and sirens that can be heard in the distance. This was recorded in San Francisco so it's pretty hard to avoid those sounds when outside.
