Besides music as created by humans, sounds of all kinds fascinate me. The vibration underlying sound is, in my opinion, the most underrated and sometimes disregarded human stimulus.
To that end, I discovered an amazing site called Aporee that celebrates the wonder of sound. It’s amazing how much ambient sounds can tell you about places and people.
Check out http://aporee.org/maps/ for an amazing tour of our planet using your ears. You can browse around a googled earth but instead of trivial data about the locations for you to read, you get glorious sound!
Pure sound, usually recorded in stereo, for free to take yourself right to those places. No HDTV or even film experience can get close to what pure sound can convey.
Close your eyes and it’s amazing how you can travel to that place and learn so much through just your ears.
