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

RE: Tidal/MQA Access Question

What I understand
MQA comes as a 24/44.1 (or 48) file
The first unfolding take the part below bit 17 and expands it to the 44-88 range.
This part can be done in hardware but is allowed in software as well.
Basically MQA say 24 bits are nonsense and can be perfectly used to store the compressed 44-88 part.

As the watermark of MQA is in the 1-16 bit range, a DAC will recognize this watermark if it is MQA enabled and will do the second un-folding
This is a matter of plain up-sampling and applying the specific MQA filters (if the DAC has a programmable filter bank)
This part is allowed in hardware only and this hardware should not have a digital out (copy protection)
