CD or both simultaneously was pastrly DSD or SACD made it possible to save
what could be lost forever. Or atleast this the story that was told by SACD
white paper.

If you mean, DSD was originally developed as an archiving medium, that's so.

Yet interestingly, DSD was exposed as having a fatal and fundamental
flaw, so totally failed as an archival medium, and the hybrid DSD-Wide
is now the Sony studio standard.

Deutsche Grammaphon, for one, agrees. They archive in PCM.

and the hybrid DSD-Wide
is now the Sony studio standard.


I've left out, too, the whole aspect involving expiration of
CD-related patents as an impetus towards developing a new format....

The "fatal and fundamental flaw" had to do with digital signal processing
which is utterly irrelevant to archiving!

It's also debatable that there is any practical problem at all since all
analog recordings have this very same "fatal and fundamental flaw," namely
that both are not "perfectible" in the future.

When PCM recording finally gets perfected, maybe we should look at this
issue again. Meanwhile, I'm not holding my breath just because a bunch of
folks who hold patents in PCM technology want to take cheap shots at a
technology that recently became part of the public domain.

No, it had to do with overload of the ADC, which is pretty darned
relevant!

However, 24/96 PCM vastly outstrips the capability of *any* analogue
recording medium, so may reasonably be considered 'adequate' for
archiving masters in a way which will allow infinite humbers of
submasters with zero degradation.

It was always perfect in theory, all we lack are perfect ADCs.

There *are* no patents in the basics of PCM, since it's been in the
public domain for *decades*.
