The Black Hole......

What about the idea that the "changing the envelope changes the sound perception" supporters start a separate thread.
Then this thread, now completely dominated by this subject, will be free again for other discussions.

On the CFA thread A few years ago, I tried to get the VFA guys to go away with that approach. Didn’t work. They redoubled their efforts.

But I ended up enjoying being a heretic.
 
Vaccy,

Pretty sure I can select a loudspeaker system for you to compare MP3 to CD where you would be unable to tell a difference.

Brings up the issue you really can't prove a negative result only a positive one.

Now let's see how much noise that can generate.

That is why they conducted this particular test on a wide array of systems, high end, studio, electrostatics. All the same nil result. No cigar this time.
 
But you can never focus a blurry picture, if your source is as focused as possible then it allows for a finer tune in final playback.....no?

But for a miked up drum kit its a Hannah Hoech montage not a 'sharp' picture. It's the mixing engineers idea of what he thinks you think a drum kit should sound like (or what he wants to give you). Look for how Glynn Johns did Led Zepp drum miking for a more purist approach.

What else ya got Hans? No need to be a playground bully! 😉

Hans is not the one being a bully on the thread. I tend to agree with him that this theory needs to be spun off to be tested now. Too many pages of no progress on that, which whilst is how BT went we did hope to cover many topics here.
 
Well Bill, must admit I never knew that, and that’s exactly how I ended up miking our sons band drum kit.....two overheads and a kick. Gave me the best results with the limited equipment I had. Those recordings are still buried in storage but hopefully we get the new house Certificate of Occupancy permit on the 18th (if it passes inspection!) and I can start emptying into the house.

You fellers have no sense of humor, it ain’t like the future of humanity is on the line here!
 
u/s I believe meant ultrasonics

Pfff, if it's that easy I'm not interested (must have been something with forrest and trees) 🙂

@mountain bob;

That’s kindly what I thought but didn’t have the energy to argue anymore.

I'd guess that these statements that you've made led to a bit of confusion:

" There’s still something about that doesn’t make sense?

Hi res sounds better than cd until you downsample it to cd resolution!?"

and

"They were comparing CD to downsampled hi-res (to cd 16/44.1)

How did they expect it to sound any different is what I’m asking?"

In their experiments they were comparing so-called (or assumed) "hi res" sacd converted back to analog to a rerecorded version (recorded by a 16bit/44.1 kHz system) that was converted back to analog as well.
No version was downsampled for comparison.

The statement in the article about the sound quality advantage of the "hi-res" records was just a general one. They listened to these "hi-res" records and found the sound quality much better than that delivered by most CDs they had at hand. See the list from the accompanying website that I've linked in my response to Markw4's post.

Listening to these records from the list and comparing the sound quality to any set of CDs they had at hand led to the impression that the newer/modern records offered just better sound quality overall.

Ive always been of the attitude ‘give it your best’ not ‘it’s good enough for the rest’ so when people say ‘most can’t hear a difference’ it really irks me because I might be one of the ‘some that can’ why should I concede to that kind of reasoning?

That is quite similar to my stance on it. Doesn't mean that I'd prefer "no music reproduction" over "music reproduction of not so good sound quality" .
And it must not be me, who is able to detect something but some others.

Has anyone tried (or even capable of) doing the wavelet transform of those cymbal strikes. The whole phase/timing keeps getting glossed over for the fr?

It is interesting. Considering that speech and music are non-stationary signals and that our hearing sense must be able to cope with that (means is working like a time-frequency analyzer) using additional tools makes sense......

I’d just like to say I appreciate you fellers including me in these discussions, I’ve learned a lot here even if it is at the expense of some of your patience’s!

I know I know I’m not trained in EE but I am a self trained consumer/listener and I think that might bring a little value to the table. 😛

Accordign to the authors the majority of tests was done on their main system, some sets of trials were done on the other systems. It is exactly one of the (quite dubious at least to me) surprising pecularities of these experiments that nobody did taking notes, neither of the number of trials done overall nor of the records used or the number of trials done on each record.

I don't understand which way the analysis that they've mentioned in their article:

"We have analyzed all of the test data by type of music
and specific program; type of high-resolution technology;
age of recording; and listener age, gender, experience, and
hearing bandwidth."

could have been done; it might be that they meant something completely different.

Since we know which sources they used, why not doing it in your own well controlled environment and report the findings.
This is absolutely meant as a positive suggestion.
I never found a difference when downgrading sample rate and word length of Hi-Res, but that’s just me, I don’t pretend that we all have the same hearing ability.
But at least I tried.

There's a line in Nick Hornby's How To Be Good that stuck in my mind mainly due to it's "perfection"; A character is attempting to make him doubt his judgement, I can't remember about what, anyway, he says to himself: "I know that I know that I know that" as a self-affirmation
