Ears vs. Instruments

Thought you guys might find the following interesting. http://www.rogernichols.com/EQ/EQ_2000_02.html I also suspect that responses will be predictable, but perhaps not. As I mentioned in my previous response, Harry provided the first "predictable response" to his own post, simply in what I would assert is his clear mischaracterization of the topic as "Ears vs Instruments." In reading Mr. Nichols' text, we find, in fact, no such conflict between ears an instruments. Why, because nowhere does he mention any attempt to use the relevant measurements. I have no doubt that Mr. Nichols' experienmce is quite real, and, from other sources, I have no doubt of the problem in the stamper that could lead to the problems. But Mr. Nichols simply failed to carry out any relevant measurements. He talks about looking for gross errors and finding none. He jumps to the conclusion, based on almost no objective data, that the problem is jitter. He may well be right, but he has no confirming evidence. There would be plenty of ways to confirm his diagnosis: simply looking at the noise floor would be one way, and actually (gasp! horrors! zut alors!) actually MEASURING the jitter would, i might humbly suggest, be yet another. But that was NEVER DONE! So where, Harry, is the supposed conflict between "ear" and "instrument" that you see, when, in effect, no "instrument" was used? He never said that appropriate instrument measurement failed to reveal the problem. What he DIDN'T say was most eloqient: he never made ANY relevant measurement. A completely similar argument could be raised if he measured the bejeebers out of it and never once listened to it. If jitter was the problem, you'd see it trivially in a high-resolution spectral plot, you'd see it trivially in a straight jitter measurement. Now, with that in hand, where is it reasonable to title a post "Instrument vs. Ear"? Again, I am sure Mr. Nichols' experience is quite real. I am also sure that the conclusion you seem to want people to infer is simply unsupportable from his data, because he has NO data on "instruments." Indeed, he does not state otherwise. Where's the conflict? |

Ears vs. Instruments
Yes is interesting, dare we say it would also be interesting to do a dbt
using the material he used? All we have at best is an anecdotal example which would be better supported with controled testing. All that is required is to have one cd from the "good" category and another from the "bad" and let him rip, as long as he doesn't know which is which, as he did in the article. Based on the article, we don't know with any certainty if all he put himself through was a waiste of time or if it had any reality outside of his self reported experience of it. A more accurate subject line, based soley on his report, would be "reported perception vs. reported perception". Thought you guys might find the following interesting. http://www.rogernichols.com/EQ/EQ_2000_02.html I also suspect that responses will be predictable, but perhaps not. Harry.

In the *only* measurement he did, Mr. Nichols found that the 'bad sounding' and 'good sounding' versions were bit-perfect copies. Assuming jitter is the problem, does that mean that the computer CDR drive he used to transfer the tracks to hard drive for analysis corrected the jitter problem, or does it mean that jitter does not change the bits? (Or does it mean some other thing I'm not thinking of?) -- -S. |

Where's the conflict? The conflict, Dick, was that SONY and the production plants were all using conventional measurements that they *thought* provided adequate quality control to insure that the finished product would sound like the master. And these measurements were all based on the "bits is bits" assumption. But the ear/brain combo said "something doesn't sound right". And by eliminating possibilities, the problem was narrowed down to the point where the *important* variables creating the problem were eliminated because somebody else had apparently determined the same thing and made sure those variables were eliminated. Apparently that Denon plant and the JVC K2 people (that's their XRCD24 line, btw, I believe) trusted their ears too, at least the JVC people claim to use rigorous listening as well as measurement in setting up their system and Denon is routinely praised by Audiophiles for their sound quality (and where John Eargle is (or was?) chief engineer). So, could it be measured? I'm sure, if one knew what could cause the problems in the first place and then track them down. But were the right variables measured? Not routinely by the production engineers convinced that "bits is bits" and if you don't measure bit errors "do we really have to listen?" Yep, when all is said and done, there is no substitute....at least until one has proven that *all* the audible variables are under control. p.s. the "they weren't dbt'd and probably the differences were imagined" chorus has started. But I am pleased that your are focused on the measuremen ts, because that was my own focus. As I am sure you will yourself agree, sometimes their *are* large differences so apparent to a group of trained people that the differences can be accepted as a given. In the antidotes portrayed, there were tests and comparisons done which resulted in a "no difference" when it would have been quite possible to have been biased in favor of finding a difference...for that would allow the problem to be solved. Instead, "no difference" was declared and the search continued. I frankly am convinced that in this case the differences were real, and am more interested in the QA measurement scenario. |

Unless something has happened I don't know about I am unaware of John Eargle's (IMO probably the finest recording engineer that has ever lived) association with Denon. Perhaps you are confusing Delos with Denon. Oops, my bad! I did make that mistake and in retrospect I know better. But glad we agree on mr. Eargle's credentials and reputation...although I might put Marc Aubort up there with him. But that's not why I'm posting. I want to convey another anecdote. I know a fellow who wons a cd production facility. He recounted a story where a large Japanese company complained about production samples having 'inferior' sound quality. He copied the defective samples returned to him, reproduced same, relabeled some of the 'defective' product and sent them all back. The client then found them all to have acceptable sound quality and was happy that he had 'fixed' the problems. These anecdotes have no end but by themselves deserve no evidentiary status. No doubt people can be fooled but that wasn't the case in the article I referenced. |

Mr. Nousaine,
Care to do like Harry and gives names and company details. Whether it is or not I don't know. But your anecdote has all the markings of something made up. Wonder what the large Japanese company would have thought of this tactic if they had found out? Wonder if something had been amiss and they decided this CD plant couldn't fix the problems? Wonder if owners of CD plants handle other complaints this way? By doing nothing more than a little sleight of hand.

So changing labels on a product, giving the same product to a
customer, who you have gone out of your way to mislead into thinking is a different product when it is the same isn't sleight of hand? Okay, what is it? It isn't truthful. Harry's comment about John Eargle falls under a mistake. Doesn't appear to be made up, simply a mistake. Dennis "Nousaine" wrote in message ... "Dennis Moore" wrote: Mr. Nousaine, Care to do like Harry and gives names and company details. No. But Harry made up some of his now didn't he? John Eargle was not, as is not new, Chief Engineer of Denon. Whether it is or not I don't know. But your anecdote has all the markings of something made up. It was related to me by the owner of a cd making facility. I cannot vouch for its truthfulness. But Harry can't vouch for the truthfulness of his anecdote either. On the other hand, I know an engineer at a BMG facility who has related similar "your product sounds bad" experiences. Wonder what the large Japanese company would have thought of this tactic if they had found out? 'Dunno but if the 'new' ones sounded better than 'themselves' perhaps they would have apologized. Probably not Wonder if something had been amiss and they decided this CD plant couldn't fix the problems? Wonder if owners of CD plants handle other complaints this way? I'm guessing only in those cases where investigation revealed there was nothing wrong with the original product. By doing nothing more than a little sleight of hand. Dennis Why do you consider that sleight of hand. They investigated the 'problem', found none and satisfied a customer. But that's not why I'm posting. I want to convey another anecdote.

If you like, I will seek out the online diary of a recording engineer, where he recounts the commonplace occurrence of 'sweetener' knobs in control rooms, which exist ONLY to placate annoying record producers looking for that 'extra something'. The knob isn't connected to anyting, but careful adjustment, in sight of said producer, accompanied by asking 'Does that sound better?" seems to always do the trick.
