I'm sitting in my living room listening to Thievery Corporation
's Babylon Rewound
on the home stereo. A lot of this glorious music is coming from the general vicinity of the speakers, but there is a significant part coming from hard to my left, about two meters to the left of the leftmost speaker.
Really? Between the recording, the playback hardware, and my brain, I am hearing stuff coming—quite clearly—not from the left speaker, nor the right, but from some place quite far away from both. How can this be?
