And by adopting this old cliché...instead of attempting to find a proper metric (if it exists), you open the door to charlatans.

Certainly not the intent. A good metric would be ideal. Right now I don't have one, have to make do with what is at my disposal.

<not how we do it for> space communications

Ah, yes. True. Very different budget and research resources applied over time to that. Most perceptual research is done on a shoestring budget. Okay in the early days when rough measurements were better than none.

EDIT: No NASA budget needed though. What the food industry spends on perceptual research should probably suffice nicely.

I have a Furwangler doing Beethoven’s 9th at the 1954 Lucerne Festival. In immaculate condition and I listened to it only once. You are welcome to have it - PM me your address if you’d .ike it. Just sits on the shelf here.


Will do, thank you. Just finished Fischer and Furtwangler doing beethoven and not sure whether to go EMI or RCA for my next 'before I were born' fix 😀
 
Upsampling can not create new information, it can only add artifacts due to necessary compromises in implementation or deliberately added effects ...

Not the whole story. Some DACs may sound better despite the compromises in DSP processing for upsampling. More gained than lost, is the goal. Imperfect choices, pick one.

EDIT: No matter what is posted in this thread, seems like always risk of misunderstanding (for content, intentions, or both). Not just by one person. Likely a limitation of forums combined with people having naturally different points of view (biases).

With that, I would like to bow out again. Bye 🙂

.... and you just ramble on more or less incoherent - totally amazed by our own voice... and technical superiority - in all this I can almost hear your mind going full spinn in french - struggling to convey your last ingenious sentence which you surly believe is the final logical "check-mate" into frenglisch - once satisfied, adding a few hyphens here and there to confuse the evil enemy and then... you smile triumphant as you hit the Post button - and voice loudly - Take That!

;-D

What do you want really? Why are you here?

Scottjoplin, if you don't believe that all the amps, all the integrated circuits, all the components we use sound (and measure) exactly the same, you have to accept that some people don't just choose their clothes for the insulation that they provide, but try to harmonize the colors.


Of course in an ideal world. But we all focus our attention to different details, our speakers are not the same, the recordings have all their character and bias. To re-use my previous image, it doesn't seem crazy to me someone want to adapt his outfit to the circumstances, although, like you, it's not my thing.


Conclusion, 16-44.1 seems perfect for you and you are an happy man.

All the previous has not so much interest when it is about what some can hear or not. The theory is nice, but limited at what it is.
As the laws of mechanics don't say much about our feelings behind the wheel of a car.
A nuance may-be too subtle to be understood by SYN08 master that takes what he have to believe in in books or other's opinions and, after, want to imposte-it to all others.

We are not listening to sinusoidal waves, but to very complicated musical signals that vary constantly both in frequencies content and envelope in time.

I'm totally sure that, if you compare (resampling them to 24X352.8 kHz ?) the two analog output contents of the two samples you compared, you will find differences in datas.
Now that you, or another guy, can hear or not those differences is another question, that only you can decide for yourself.

It is nevertheless curious this need to constantly refer to theories, books or the opinions of others, when it is so simple to trust our own feelings ...to feel aggressed when others do it, who only speak for themselves.
24-96 choice is not something AGAINST the laws we believe in of physics. It address something highly subjective: The human limits of audition, tastes, feelings. It is music, a lot more than the simple intelligibility of conversations between the moon and the earth during a spatial exploration.
 
Upsampling can not create new information, it can only add artifacts due to necessary compromises in implementation or deliberately added effects (the ken of the snake oil merchants).
If I mentioned sampling (the analog signal) to the highest definition available, it was to be sure that this part of the test was not the restricting factor.
A measurement instrument need better performance than the one of the thing to be measured, isn't it ?
We could make the difference in analog subtracting the signals, but how to synchronise them ?

I"m sorry if you did not understood my words.
By the way, it is not enough to say "incoherent". You need to demonstrate-it.
I am here to can exchange with other's experiences about AUDIO.
Not to be flamed by a little pack of hunters that turn crasy each tome some refer to a listening experience. Always the same guys.
Where is your problem ?

Oh, I see, because not enough (in your imagination) money was spent on audibility study of audio electronics, we still don't know enough about what can be heard when spending more $$$ on DACs and cables and therefore it cannot be ruled out when someone like you claim to have heard differences. With no mention of any numbers, it's a strawman argument, the typical move by audio businessmen seen all over the net.

Of course, in subjective auditioning sessions you've engaged in.

As if that means something. 🙄

The quote below (response to T) clears it up.
you seem to prefer to make a fool of yourself for the sake of attention you crave for. Which I'm making right now the mistake of feeding.
T has noticed a vast reserve of "food" here and that's why he came back after announcing "Goodbye" earlier this year.

Mark said he's going to post some evidence..........🙂

Not holding my breath. Talking and being creative in describing the SQ is cheap, presenting evidence not so much. I have even collected, over the years, a long list of excuses for not doing so.

If I would get a dime each time I've heard such promises I would be long retired by now 😀.

The 12" single sleeve was cut to look like a floppy disc. And had no mention of the band or track on it until you took the record out. Apparantly cost so much to make the record company lost money on every one they sold. But an iconic cover in the UK. Mine would apparantly be worth £50 if it hadn't got water damaged during a move.

The very first stereo cutter heads weren't quite as good as the contemporary mono cutters. The early post-war LPs were a combination of shellac masters, often pre-war, and the first tape masters. Creaky old sound to modern ears, but performances by people who knew Mahler or had learned from Joachim.


That's what I call musical realism. Arf!


All the best fortune,
Chris
