[ProAudio] [ProAud] The High-Resolution Challenge

Tue Feb 11 07:36:32 EST 2020

The HD-Audio Challenge II has garnered around 200 submissions. Participants downloaded the 20 tracks in both hi-res (96/24) and CD Spec at 44.1/16 bits. These were native, non-compressed, non-mastered audiophile quality recordings from my AIX Records catalog. Preliminary results seem to confirm my suspicions that no one can successfully identify the hi-res audio version over the CD version in their own systems at home. In fact, a large percentage of the respondents said they couldn’t detect any differences between the two. I’m going to continue the survey for a few more months. An online magazine has agreed to promote it…I wrote an article for AudiophileReview.com that should show up soon. My hope is to get a younger demographic to participate. The average age of those that have submitted results so far is around 50 (my readership).

Anyone or company that claims that distributing music in resolutions higher than CD is pushing a narrative for marketing and profit reasons NOT for higher fidelity.

My experience at NARAS, CEA/CTA, and the DEG is that increasing sales for hardware and software sellers is the prime directive. And now the myths are being pushed via HD Audio streaming. AMAZON Music HD has redefined CD spec as high-definition!

The is little chance that honesty will prevail IMHO.

Following on from our discussion of around 18 months ago,

I know in Australia there were moves to get some kind of "truth in marketing" 

in regards to High sample rate recordings.

And promoting the differences in standards that are now available. 

Essentially a standard that could be understood by and promoted to consumers, musicians etc.

It doesnt seem to have gone far and when you see things like this

It makes you wonder if things will improve.

Is there any consensus on getting this acknowledged? 

regards

Mark

In the interest of exploring the issue of perceptibility of high-resolution vs. Redbook versions of the exact same file, I've posted on my blog page today "The High-Resolution Audio Challenge". I've prepared 6 of my AIX Records native 96 kHz/24-bit PCM masters as A and B versions. One is the original high-res master and the other is a Redbook downconversion. You are welcome to download the files and play them. Please do not share them outside of the group. I'm conducting a casual survey to see if people can detect differences. I don't claim this will be definitive. However, I've always complained that previous tests failed because the source materials weren't actual high-resolution files. This removes that flaw. These are the real deal. The conversion was done using triangular dither and noise shaping.
