No that is not what he pointed out. He made a big deal about the

If the point is that someone on this forum said something like that, it is
meaningless. With all due respect for our esteemed moderator(s), nothing
posted here goes through a proper editorial review by a duely credentialed
editorial board that is poart of an internationally respected a
professional organization such as the AES. Thease are all casual
conversations.
Well, no, as you're fond of saying, you don't get to speak for other
people. Mr. Pierce said, and I quote:
"What is done is immediately BEFORE the quantization step, a process
known (in the simplest case) as "dither" is performed. This is
essentially the addition of a small amount of random noise, on the
order of an LSB, to the signal BEFORE the quantizer. It's function
is to essentially randomize the statistics of the quantizer. The
result is that you ELIMINATE (that means, you make it go away)
the quantization error in the qauntizer."
Note the use of "ELIMINATE" - not lower, not reduce, eliminate
quantization error. Your characterization is flat wrong.
Agreed.
If you think it isn't you are simply wrong.
He is certainly correct.
Assertion is not evidence. How about some citations?
I'm sure that anecdotal evidence from any number of musical artists,
recording engineers and mastering engineers can be provided. This speaks to
the fact that these people are primarily artists, and are not world-class
technical experts even though their professional endeavors may involve the
exercise of certain non-trivial amounts of technical expertise.
