Over the years various people on RAO have berated me because I have kept
saying that the fact that the CD format removes all sound above 22 KHz
isn't
a problem. Here is one more example in a long series of scientific papers
that agree with this idea:

Audio Engineering Society Convention Paper 5876: Perceptual
Discrimination
between Musical Sounds with and without Very High Frequency Components
Given
at the 115th AES Convention in New York about a month ago. This paper can
be
ordered from the AES web site: www.aes.org .

This paper describes the test methodology and the results of a series of
listening tests performed by researchers at NHK Science & Technical
Research Laboratories, Tokyo, Japan. These tests compared the playback of
recordings with and without audio signals above 21 KHz.

So, you can flip pennies or compare 24/44 to
24/96 and get pretty much the same results,
provided you hold all other relevant variables
equal.

"relevant variables"... you have not demonstrated that.

Powell, since you seem to be very weak on the concept, let me advise you
that this is one of the things that happens when you read the paper that was
cited. Copyright laws and newsgroup rules prohibit posting the whole thing.

Without knowing the exact methodology, subject
screening and training, equipment used, et cetera...
the results are interesting but not conclusive or even
necessarily scientific.

That's why I gave a proper cite of the paper I quoted, including how to
quickly get your very own copy for a nominal fee.

Given it's a Audio Engineering
Society paper I suspect this study had a near zero
budget and no leadership prominence.

Big talk from a guy who just learned how to hook up XLR mic cables last
week, and is still struggling with trying to use a consumer sound card for
audio production purposes.

folks, I kid you not!
