Upsamplers, DACs, jitter, shakes and analogue withdrawals, this is it.

It is possible via post processing tho recreate some of the original data if certain info is known. For example, if the ADC has a sonic signature and creates artifacts, the info is known an therefore can be utilized to recreate or correct the data. Not all info has to be present in the data stream, it can reside elsewhere.

The HDCD process in a way does this even though more info is hidden in the lsb. Think of it as a self swithing autocorrection.

Decimation itself presents certain artifacts which are predictable. because of this, we can improvise and "sometimes" recreate the data that was lost before hand.
