I recorded with my sony recorder some nature sounds in berlin buch. There is an autobahn near the forrest which i filtered a bit out in the deep frequencies.
Edited from a sound that i uploaded recently. I removed the sound of something tapping the microphone. Sound of birds in a forest. Recorded with a phone and edited in audacity.
This was recorded incincinnati ohio. Then processed with gold wave to make loop-able. This was recorded with a winbook desktop webcam. Amazing the quality that it produced, could be better but still not bad.
