High Definition Audio - Can You Hear The Difference?

I hope nobody minds that I posted this in several Facebook audio groups. My goal is to collect enough responses to report the results with confidence. If anyone would like to share this further, I'll be most grateful. ?

I created a set of music files that lets people learn if they can hear the difference between "high definition" audio at 24 bits and 96 KHz, compared to standard CD quality at 16 bits and 44.1 KHz. The main feature of a self-test like this, where people download files, is they can listen as many times as they like in the comfort of their own environment through their own audio system. A self-test also avoids people complaining that someone else's audition system "isn't revealing enough to hear the difference" as an excuse for why they can't tell one file from the other. So please read this short article, download the files, and email me your choices. When I have enough data I'll report the results on my own Facebook page.

I firmly believe (in old recordings pre 80's) some vinyl rips sound better than same albums CDs...though...(ABBA, ELO, Elton john, Bee Gees...those guys CDs SUCK!) PS: member it was meant for AM radio...)

This is because the smooth wonderful excellent ABBA productions Treschow made has been multibandcompressorprocessed by Treschow with a treshold-shift in the sense of hearing to match a more modern sound. I have found that I like multibandprocessing better myself with the hearing treshold on its age related upward climb. Similar sonic disasters - ahem updates - have probably been done in remastering the other smooth stuff you mention.

To be fair to them actually re-releasing the vinyl mastering would necessitate recording off of a grammophone record because of the inline processing in the record cutting process. So they have just used the contemporary tools and the contemporary production style.

Ethan, it is a possible source of error if identical dithering is not used because soundcard truncation may obfuscate the results.

Dither affects only the lowest bit, and I doubt anyone can hear that while music 80+ dB louder is playing at the same time!

No one has heard one stage of dithering to this date unless there are obvious problems. it is mainly just theoretical "feel good" thing as it does make one happy that you know you just lowered the noisefloor. We know it works but no one can tell if it is being used or not. The worst we can do is dither multiple times, something i can admit being my modus operandi in the past (TIP: schools are a good place to learn about the things that exist but can't be heard...)...

Pono was much over hyped BS, from Neil young, and his con associates...now he gives music away...old age has taken it's toll...MQA, is the latest con......the last actual improvment was CD, turn it into a digital world, portable, reliable. DSD/SACD was a nice tweak of same science.and a chance at keeping money stream, as Cd patents where running out DSD/SACD, would extend it, it didn't take off as Philips/Sony wanted. It's always about the money. Patents matter, it's BUSINESS.SACD came out just as CD patents where winding down, how coincidental.. by the same innovator Philips...DSD sounds better on certain stuff, sometimes not so apparent, lots of times lately, I don't give a shit...just listen, I must be getting old...

And you know why Sony bought CBS, right? So they could keep reissuing the back catalog on one more format after another, both recorded music and the movie archives.
