We had a thunderstorm blow through a few days ago that knocked the power out for about a day. I pointed the recorder at a skylight in our attic and let it run for a little bit. Picked up a lot of rumbling thunder, distant sirens, wind, and rain hitting the skylight.

Recorder: Zoom H6 Mic: XYH-6 X/Y Capsule 120 Degrees Gain Setting: 5 Processing: Normalized gain. High pass at 80Hz. Low pass 12000Hz. Seemed to just be distracting white noise.
