Winchester cathedral ambience. Recorded in ms and xy stereo (combined for 4 channel surround). Distant visitors walking and talking and a organ playing in the foreground.
This was recorded in a large theatre. It is not completely silent so it has a nice unique tone. Recorded on my h4n at 24bit/48khz using the built-in stereo mics.
Quiet ambience of a city park. Some urban noises very far away. No traffic. Recorded in 90°xy with a zoom hd2 at priesterweg, berlin in september 2016.
