anyone who wants to try vinyl rip vs. sound file
http://pmacura.cz/alabama.zip
What do you want us to do with those files ?
It is probably a comparison between an original vinyl that you ripped and its digital copy, ripped by the record company, if we believe all this distortion, this lack of transparency, micro dynamic and clarity in the two files.
It demonstrate only that both turntables used to rip this vinyl used very close performing cartridges, if not the same, and that digital is pretty reliable. That everybody knows.

Measuring all relevant aspects of an electrical signal, for example, and drawing conclusions about how it will sound from that. Much progress has been made thusly by the scientifically inclined.
This is how measurements can help since:
Mapping of measured differences to perceptions is still a demandig and ongoing task (I didn't read your post as if you'd think it is already over and done) especially as different sound events can lead to the same percepted impression and considering the high variability between humans.
And isn't it also the case that the same sound events can lead to different perceptions? Unless this mapping is done on an individual basis it has limited value in correlating measurements to perceptions
 
actually no version of Pro Tools has any ADCs or DACs. Pro Tools is a software program that can use anyone's converters. Most upper tier people do not use Avid (the owners of Pro Tools) converters, even though the latest incarnation is much better than previous ones, still not as good, and indeed the previous 2 generations were dreck.

The HD 192 I/O. I thought they were bundled at some point.

You know maybe letting go and becoming absorbed into the music allows one to hear it differently?

And I’m not sure it’s all as individualized as some portray it to be, I think people that are well versed in listening to high fidelity music may share much the same experiences/perception (whether they admit it or not)... I also think referencing a torn AM radio speaker in comparison to a well setup systems ability to carry emotion is rather undignified.

Only because I couldn’t afford them Jensen 6x9’s :D
To make this discussion relevant and convince everyone I am senile;

In the mid-70's I worked at an Altec/Hell & Bowell/Ampex dealer as a service tech during the day and installed car stereos at night. I noticed the Jensen 6x9s with the whizzer cones sounded a lot better than did the ones with the coaxial tweets, so I brought them to work and tested them in a small cabinet....I had access to an Altec/HP 8050A RTA and the on-axis response of the whizzer version was smoother than the one with the cap-coupled tweeter. No funky stuff happening in the crossover region.

Thanks to employee discounts, I ended up switching to, and installing a lot of Altec 409-8C coaxials which were great sounding little speakers.

Back to ...whatever the fuss was about.

I have a Columbia recording (CD) of the NYP (Bernstein conducting) that has amazing dynamics, its very quiet and the imaging has to be heard top be believed - left to right and front to back.

Looking at the liner notes, it turns out the recordings were made in 1961 at the 'Manhattan Centre' and the other on the CD at the St. George hotel, Brooklyn in 1959. So these are ~60 year old recordings.

So its an ADD with the original music captured on tape. My point is, you don't need a zillion bits or a zillion samples per second to recreate the ambience and space in a recording and really be able to enjoy it.


I have some Ella Fitzgerald vinyls and CD's - also fantastic. The recording quality (and the recording engineering) makes all the difference.

We are mixing up subjective issues with engineering here and its like oil and water - there are 'correct' ways to get high performance through engineering, but as I said a few posts back, it will not guarantee a satisfactory listening experience.

(ScottJoplin, its the same CD I showed the picture of a few weeks ago)

Although I agree the better a system is, the more the original artist's intent may convey, I would argue the emotional content in music is entirely individual and situational. To discount the strongly emotional response to music experienced in a old car is wrong; if that is where the music is experienced in a meaningful way, then it is a valid experience and emotional response. To hypothesize the response would be stronger on a high-end system is missing the reason for the emotional response.

Experiencing a favorite artist live can be overwhelmingly emotional due to the volume and visual stimulus. In most cases this cannot be considered an aurally high-fidelity event.

Loud, aggressive thrash metal will indeed induce panic in most humans, but only played at a loud volume. It is rather benign at low levels...like a form of pink noise.

There are particular chord sequences which seem to elicit similar emotional responses across many cultures, but that is the content of the music, not the fidelity.

There is no technical parameter of an audio system which is directly or indirectly associated with emotion. Emotion is a user defined parameter.

Cheers!

Have you tried it? The digital file is not a vinyl rip made by a record company, this is a ridiculous idea.

What do I want for you or others? To check the files and show if you can find a difference in an ABX test. Because many here speak about audibility of subtle differences, SOTA DACs etc. In these files, there are huge differences. Huge differences are easy to hear, isn't it? So I prepared a poll
Can you tell vinyl rip from digital download? listening test

and no one is willing to take up the glove. Afraid of possible failure? Do not want to show possible bad result? There is always much talking here, when it comes to the proof, excuses take place. As always.

Fidelity - As music had evolved into the manifacturing of different instruments, the sound that they make should be restored during playback.
It's like the evolution from fortepiano to pianoforte - the emotional stimulus had to be more vivid, the contrast between the high and the low [emotional] register more pronunciated, hence the technical improvements to the body and the percussive system.

Sorry, but, as someone responded to me some day ago, it's rubbish!
:eek:

But this is the real one!:p

Why would you want to play a disc in digital format when you have the (full) analogical system to do it ?
It's the winning card of analogic.

Otherwise...
Of course it will sound different
Of course it will sound worse
Of course it will sound "dinamically limited"
Etc

Thanks for that Howie,

I’m not sure we’re talking about the same emotion response?

When you say situational it’s as in reminding you of something or someplace because you heard the song before?

What I’m talking about is the raw emotional response to music you’ve never heard, and lyrics don’t even have to be relevant to the emotion (or even there at all).
This raw response I’m referencing can come and go (repeatable) with gear changes......I’ve done it.

This ‘emotion’ in the playback is something I strive for in a setup.....a oneness with the music, if it’s not there I’m not happy.

I really have no idea what ‘it’ is.
