Actually you can sometimes see that same effect with your eyes, watching the hubcaps of a car pulling away from a stoplight. As the car (and the wheel's rotation) speed up, the pattern on the hubcap will sometimes appear to slow and begin to rotate backwards. Presumably (although there is apparently some controversy about this) this is due to some sort of "frame rate" in your eye and/or brain, and so is an example of this kind of aliasing artifact. -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=24693 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
