They do have a sampling rate but it's probably very very high. The speed of a state change across a synaptic gap. That isn't what's causing your prop blade effect. It's the "sampling rate" of the reflection as the surface of the water is slowly moving up and down (rippling) under gravity and/or air movement - this is the same effect as car wheels on movies where the frame rate is interacting with the frequency of a moving object, creating an optical illusion. Otherwise, we'd all be queuing for upsampling brain ops! -- Phil Leigh ------------------------------------------------------------------------ Phil Leigh's Profile: http://forums.slimdevices.com/member.php?userid=85 View this thread: http://forums.slimdevices.com/showthread.php?t=24693 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
