A while back I came across the subject of holophony or holophonic sound, which is an audio recording technique that results in realistic and life-like 3D sounding audio recrodings. Holophonic sound recordings should be played when wearing headphones, and played at a reasonable volume. This improves the listening experience because you can hear the true effect of the recording.
Pink Floyd even used holophony in the album “The Final Cut”.
You will hear someone lighting two matches, first on your right and then your left. You then hear him/her shaking the box of matches all around your head. Listen to it with headphones!
The file above was actually featured on digg several months ago (where I orignally found the file back then), and became subjected to the Digg-effect - that’s how good it is!
