I was trying to record the haunting sound of wind in the trees when this happened...
Directly below the blades of a wind turbine at Whitelee Windfarm. Tascam DR-05.
Stereo binaural recording of a day at a very quiet lakeshore beach. A jetski goes by twice.
Tram comes, stops and goes. Prague, Czech Republic. Recorded with Sony D50 (internal mics).
