....that each signal level gradation in digitized recording has a minimum threshold, average level, and maximum threshold.... (There are 65,536 such gradations on a Redbook CD.)If so, you basically described "quantization error"....
Although dither (in the A/D encoding process) does make the behavior more "fluid" when played back with a DAC using classic (oversampled) digital filtering.... Because the random bit triggering on the media (induced by dither noise in the A/D process) translates to an interpolated signal (from the D/A digital filter) whose levels are between the gradations of the media. The extra bits in an oversampling DAC enable such interpolation to take place.
