Spherical panorama test - animated in Flash (code by Denis V. Chumakov).
The sound is two stereo mixes from a 4 channel original aimed at either end of the pan. It's not quite quadraphonic, not sure what it is yet.
The files are huge and not buffered right so things will be choppy for a while even on a fast connection. This will be better once discrete (rather than mixed) sounds are used.
