This is tech radio host Leo Laporte demonstrating 3D sound through an iPhone app called Z+, made for the movie Man of Steel. Just put on your headphones (the effect won’t work with speakers) and listen to this demonstration…
By the way… The first two times, the left and right channels are backwards. They fix it for the third time.
I’ve always thought this was cool. The first time I heard this clip (about a year ago), I thought my speakers were accidentally on and blaring!
