Digital recording uses dither to achieve randomness in its individual samples, the real difference is that this randomness is achieved with *vastly* greater dynamic range than is possible with any analogue medium. Thank goodness some people were using their ears and came up with dither as an improvement on a medium that was already declared sonically perfect. You are, of course, completely incorrect here. Dither is a process that predates the introduction of the commercial introduction of digital audio by several decades. Further, the specific use and requirement of dither was specifically discussed in the context of digital audio in a number of articles on the topic that predates the introduction of consumer digital audio. For example, Perhaps "came up with" was not the best choice of words. The fact is CDs were initialy issued without the use of dither and suffered for it. No, *some* early CDs failed to use dither when the old analogue master tapes were digitised. Heck, some even used LP cutting masters, with grossly boosted treble and reduced bass! The ability of some idiots to misuse the tools, is not a fault of the available technology, See Dire Straits 'Love Over Gold' for how it could be done right from day one. Those who thought the medium was perfect blamed the source material. Those who recognized the problem saw dither as a means of improving CD sound. Those who recognised the problem laughed at the idiots who had failed to use dither. Those that recognized the problem clearly weren't those that had already proclaimed the medium perfect. That would be the subjectivists. Dither had been used for *decades* before CDs were launched, it's an *essential* part of digital signal processing. That's nice although it is entirely irrelevant to my point. Your statement: "Thank goodness some people were using their ears and came up with dither as an improvement on a medium that was already declared sonically perfect." looks pretty silly in light of the pretty extensive history of the technical literature on the topic, and in light of the actual implementation of digital audio systems over the last 35 years and more. In light of the reality of the history of early CDs it ought not to look so silly if you can get past the semantics. Fact is dither was not initially used on CDs. The introduction of dither was the result of some people acknowledging that CD sound was leaing much to be desired. Fact is that you don't know what you're talking about. Dither most certainly was used on most early CDs. Only the technically ignorant failed to use it. Prove it. Posturing is easy on Usenet. show us the facts that support your claim. That YOU aren'y aware of this, or that some members of the hi-end press are not aware of it doesn't make the fact that dither has ALWAYS been an intergral part of digital audio implementation since BEFORE the introduction of the CD. I suggest you go back and look at the history of CDs rather than the history of dither. The fact is that dither has NOT "ALWAYS been an intergral part" of the implementation of CDs. I suggest you go back and look at the history of CDs rather than the history of dither. The fact is that dither *has* always been an "integral part" of the *correct* implementation of CDs. That some idiots were unaware of this, is not the fault of the technogy. In the case of early CD's made from analog master tapes with a fairly high noise floor, that noise floor can effectively provide dithering, since it will always activate the lower order bits of the ADC and DAC to randomize the transitions. J Gordon Holt made the same argument over twenty years ago. But he wouldn't have made the argument had all those early CDs been dithered in the first place. So the resulting CD would most likely sound the same regardless of whether digital dithering has been applied. Oh, dithering is that simple? I thought there was a bit ore to it than that. Dithering is much more necessary if the source has a very high dynamic range. I guess someone clueless may mistakenly leave out the dithering when mastering a CD, but I have yet to find a CD sounding bad because dithering was not applied. How do you know? Which CDs have you listened to that you know were not dithered that you found excellent? It also takes someone clueless to conclude that introduction of dithering was due to people finding out that CD's sounded bad. Gee wiz, you got an insult in. You must be right! Insults are a far more effect way of proving one's position than evidence. SOOOO, if anyone has any actual evidence that contradicts my claims rather than insults or posturing or straw man arguments I'd love to see it. One of the best piano CD's I have was recorded digitally in 1981 and released in CD in 1983. As good a sound as anything made today. If it is the one you were talking about a while back on DG I finally got to hear it. IMO it is pretty far from SOTA sound quality. If you really think that is SOTA sound qualiy I have to disagree with your judgement on sound quality in general and that would include your opinion on nondithered CDs. If nothing else, we are prioritizing different elements of realism in playback. Scott |

Do those musicians find that a distortion could make reproduced sound more lifelike in all contexts? They find that analog is more lifelike in virtually all contexts, hence the unlikeliness that a distortion is responsible. If you wish to postulate a distortion that is responsible, you need to explain why it has that specific subjective effect.

It is stated directly in an article by Ethan Winer that appeared in Skeptic Magazine, reproduced he http://www.ethanwiner.com/audiophoolery.html It's implied by anyone that thinks accurate audio circuits can be designed by measurement. No one, subjectivist or objectivist alike, has a good handle on what patterns correspond to musical beauty. But only objectivists claim it doesn't matter. Mike |

I would love to hear your ideas on this. Yes, try to contact Jim Johnston. I remember him claiming to have some ideas on this very matter. Actually harmonic distortion in effect does know because the source of harmonic distortion is the original signal. So harmonic distortion from a brass quartet is directly related to the sound of a brass quartet. But a distortion, like any "tweak" to the music, should improve some things but not others. If you swap out the brass instruments for instruments of a different design, it might improve things---but probably only on certain pieces of music. why would you assume this? If there is an inherent short coming in the recording/playback chain (there are many actually) then why would you assume that there are no colorations that universally act as a counter to such distortions? I don't assume it. I just point out that no tweak to live music can make a universal improvement, hence it is unlikely a tweak to the reproduction would. However, I agree that two distortions could cancel each other out, or combine synergistically. So which two? What affect do they have? How do they cancel out? But then, we would agree it *changed* things, don't you think? Yes. I'm still waiting for an explanation why analog is *generally* superior, *in the sense of more accurate*, if the distortion is responsible. I think you may be asking the wrong people. Try asking Doug Sax, Steve Hoffman or Stan Ricker. Good point. It would seem reasonble to ask this on this newsgroup however, seeing as Pinkerton and Chung have stated that analog distortion is a major cause of the aesthetic reaction to analog. I remember one recording/mastering engineer claiming that the LPs of his recordings sounded better (more like the original) than the master tape. I think it may have been Doug Sax. If it was Doug Sax, wouldn't that have been been a directly mastered LP? Not always. " In that case, he's not claiming that adding an extra stage improved things.. he's actually claiming that a single stage of LP distorts the music less than a single stage of tape." No, in this particular case he was talking about LPs he mastered from analog master tapes. Well, that's interesting. It certainly would be an interesting study, to see which distortion was responsible and the aesthetic effect of that distortion. Well, that may be. I don't have a tremendous amount of experience with this. But check out Boyk's "Magnesaurus" tape recorder. Every single design decision was for the purposes of *reducing* distortion. i agree but then check out his choice of microphones and mic preamp. I believe he chose those for their accuracy. I would suggest checking out what guys like Steve Hoffman and James Boyk say about this. I think you will find that they use the distortion of tubes to increase the life like quality of their work. Boyk has told me he uses the *accuracy* of tubes, not the *distortion* of tubes. For example, he probably wouldn't put an extra tube stage in the chain to add distortion. "accuracy" becomes a dodgy term here. Now i do know that Boyk at one time felt SS components color the sound in an ugly way. So I think it is a matter of accuracy to the elements of sound that he thinks are important in the inherent beauty of live music. I have not heard him say that tubes are more accurate in general just better at getting the important parts of musical reproduction right. Since the point of audio is to reproduce an aesthetic experience, I *define* "accuracy" as "getting the important parts of musical reproduction right." Mike |

It's the population of musicians who find analog to be more accurate which is the population you are describing, when you describe the aesthetic reaction to analog. If you want to describe this popluation, then "the musicians who find digital to be more accurate" are not relevant. Even if it were a "vast majority", which is a questionable claim seeing how easy it is to find musicians who express a preference for analog, why would that matter? Mike |

I find this unlikely, just as I find it unlikely that a distortion could make reproduced sound more lifelike in all contexts. I notice you aren't responding to this. I think we are not responding to this because it is obviously true. A distortion cannot make reproduced sound more likelife in all contexts. And, guess what, it does not. And you know this how? Can you cite some published studies? You, of course, implicitly claim that a distortion is responsible for the lifelike quality, but you haven't described any distortion that is consistent with the actual experience of, say, musicians who find analog to be more accurate. Do those musicians find that a distortion could make reproduced sound more lifelike in all contexts? Obviously some musicians find analog make reproduced sound more life like than digital. *If* that s the result of distortion then the answer would be yes. It seems you and a few others are in denial about the fact that some people including some musicians find analog at it's best to be superior to digital. now I think there is a need for making this a conditional claim. Digital recording has been getting better over the years. I know that some musicians that at one time found digital lacking have come to be quite satisfied with the current SOTA. See, there is nothing to agree or disagree here. Yes, I see refusing to accept the reality of many peoples' dissatisction with digital. For the simple reason that only *some*, and not all, musicians find analog to be more accurate for *some* recordings. Big deal. We all know that perceived accuracy to one person is not necessarily perceived accuracy to another. Inexplicably? It seems to me the most obvious explanation is that analog is accurately reproducing the key patterns. Unfortunately, that is not consistent with the facts of the matter, which are that digital is *vastly* more accurate than analogue in reproducing *all* the patterns.

Or technical objective facts from preferences. And I wonder when and where did you read that "objectivists think that they have categorized all patterns" (whatever that means)? Are you saying that subjectivists point out that *ubjectivists* don't even know what patterns correspond to key "musical experiences" such as beauty? I tend to agree with you there. But what exactly were you trying to say? Is there a point there? Perhaps the great divide is that using ambiguity in place of cogent arguments, certain subjectivists make it nearly impossible to have meaningful debates. If I were a subjectivist, I would hate to have you speak for me. Who would you want? Really, who do you think has given you cause to question your beliefs in audio from the subjectivist side? Scott |

Hi Jenn, I used the word "accurate" in the sense that a recording captures the timbre of the instruments, the balance of the players and the musical "logic" behind their choices, and so on. Many musicians describe that analog gets these things better. Mike |

I have not heard any musician stating that analog is more accurate either. I was simply giving michaelmossey the benefit of the doubt. He is the one who said that musicians find analog more accurate, as in this paragraph he wrote (which you snipped) dated 2/1/06: "You, of course, implicitly claim that a distortion is responsible for the lifelike quality, but you haven't described any distortion that is consistent with the actual experience of, say, musicians who find analog to be more accurate." |

Unless, of course, the remaining flaws in much audio gear still causes "loss" of accuracy and some equipment does not. In that sense, such equipment may be said to be "more musical". And it is even possible that a small amount of 2nd harmonic distortion makes the sound "more musical", perhaps by masking other higher order distortions. |

No, it isn't. It's no wonder you prefer CDs ;-) High fidelity audio is supposed to reproduce the mic feed *accurately*. Sorry but that is simply not true since a mic feed is an electrical signal and Hifi is about producing an acoustic output. 'Beauty' is in the hands of the performer, and the ear of the listener. Riiiiiight. The equipment used from live performance to playback and the decisions made by the recording engineers and mastering engineer and the means by whcih everything is produced has nothing to do with it.

A classic case of measures poorly and performs excellently. I would suggest checking out what guys like Steve Hoffman and James Boyk say about this.

I should have been able to make the discovery that turned this thing around, but being an engineer, I was convinced that what measured the best, sounded the best! For fifteen agonizing years the audio community struggled with the realization that tube hardware used judiciously in a playback system almost always produced a more enjoyable sound and a better illusions of live music. ..... The engineers laughed at this and continued to bash anything that did not measure perfectly. In fact they were so sure that ordinary copper wire measured so perfect, the developing high end cable industry was thought to be a bad joke. In fact you still hear some engineers say that the best amplifier is a straight wire with gain. Wow, how wrong can you be! To put it simply, tubes have a sonic signature that mimics acoustic music and transistors do not. Now I'm going to lay low while the cannon shots pass over my head. It is certainly true that good, let's say average, performance is easier to obtain with solid state hardware than with tube designs. However, well designed tube equipment coupled with a good output transformer will sound more musical and is more satisfying to listen to than solid state at any price. It does take a little maintenance, but it will warm your feet on a cold winter night. The next level of sonic achievement can be obtained by use of an all tube OTL - but that's another story. ..... The real improvement in audio reproduction in the last forty years has taken place at the ends of the chain - namely good transducers. These are the devices that change acoustic energy to electrical energy and back again. Even the CD player, which begins its life with solid state technology, is a major advancement in transducer technology. Better analogue circuitry has resulted in very good sounding digital information recovery, but it still lies in the realm of the vacuum tube to produce the recorded sound musically and with realism. ..... You will notice that I don't use the term accuracy. This throws us back into the engineer's argument with the artisans that the most accurate is the best. The answer to that is a flat no.

I have not heard any musician stating that analog is more accurate either. So you have *never* read anything Jams Boyk has written on the matter here on this forum? I was simply giving michaelmossey the benefit of the doubt. He is the one who said that musicians find analog more accurate, as in this paragraph he wrote (which you snipped) dated 2/1/06: "You, of course, implicitly claim that a distortion is responsible for the lifelike quality, but you haven't described any distortion that is consistent with the actual experience of, say, musicians who find analog to be more accurate." He didn't actually say "musicians find analog more accurate" did he? Scott |

Thank goodness you don't have the power to dictate your will on everyone else. That may be the point for YOU but it is hardly the point for all audiophiles. I am of the school of belief that the technlogy is there to serve the aesthetic. You seem to believe that the aesthetic should comply to the technical. That certainly is what "The "point" of audio reproduction is to be as accurate as possible in the technical sense." says to me. you are free to prioritize the technical aspects of audio over the aesthetic aspects but no one is free to dictate that to others. That's why they are going to higher bit rates and higher resolutions: so as to be as faithful as possible to the original signal that is to be captured and replayed. I thought the market was going towards MP3. We want the output to be a faithful scaled version of the input. We? I suggest you speak for yourself. When you do that, then you are capturing all that can be captured. That way, you can enjoy the musical experience as it was recorded. Unfortunately that is an overly simplistic view of the whole picture and when implemented that wayoften failes misreably. Thankfully we have people in recording and mastering that understand thee is so much more to the picture. They are the ones responsible for the vat majorty of great sounding LPs and, gasp, CDs not to mention DVD-As and SACDs. here is a taste of the real complexities involved in creating truly outstanding LPs and CDs. http://www.classicrecs.com/frames/be...s_frameset.htm This illustrates a fine example of the care that is needed in making critical choices during the mastering process. this idea that digital solves all and all you have to do is run a straight transfer to digital is completely wrong headed and destined to wrought terrible results in many cases. To get an idea of another level of complexity in the whole process one need look no further than the paper presented to the AESJ by the folks that remastered the Mercury catalog. Seems that getting what is on the master tape onto the commercial CD is not as easy as it seems on paper. In that regard, the audio reproduction facilitates a musical experience, if you want to use those ambiguous words. Of course, you may not like that musical experience. But you have to separate audio reproduction from subjective evaluation of music. You don't. and the real masters of recording and mastering don't. Not to mention the designers of the best playback equipment. An accurate audio system is one that reproduces the original experience as closely as possible. An accurate audio system is one that reproduces the input signal accurately so that errors in the output are minimized. It allows you to experience the music as it is recorded, *not necessarily* as you may like it. Accuracy is always measured by a reference. you may choose an electrical signal as a reference but that is not something everyone else has to choose. That is also a significant difference betwen many objectivists and subjectivists. Perhaps something as quantifiable as an electrcal signal makes objectivists more comfortable as a reference but it makes no sense for those who want to recreate the sound of live music in their home. Winer reduces all possible behaviors of a system to a few categories. But life always operates outside our models of it, and the experience of a listener is the final and only test of audio performance. No, the test of whether an audio system is accurate or not can be performed by instruments. Can you cite any such measurements? I would suspect that would involve comparing the mic feed of a live event to the mic feed of a playback system using the original mic feed of the live event as a source and measuring the sound at the listener position to the orignal mic feed. Whether you will like a piece of audio gear or not depends a lot of things. On any given recording, you may like that recording more if there are distortions added, and that's OK since it is your preference. Just like someone may want to pump up the bass more, or turn up the treble. It may sound better, but it may not be more accurate. What I like and what you like are different. Accurate to what? An inaudible electrical signal? Just because you choose a reference that makes measurements an easier task does not make your reference a superior one for making astheic judgements on playback. If we use your definition, then an accurate system is simply one that you like. WRONG. First you must understand the subjectivist position before you can crtique it. live sound is not arbitrary Not much meaning to other people. Again, I suggest you speak for yourself. I find plenty of meaning in Mike's ideas of accuracy in audio. Just because You don't get it doesn't mean there is nothing to get. Scott |

We want the output to be a faithful scaled version of the input. When you do that, then you are capturing all that can be captured. This is the basic objectivist/subjectivist disagreement. The final test of accuracy is to listen to some live music, then listen to the reproduction, and ask if they are similar. Measurements are appealing, but they never capture every dimension of the system's behavior, and often systems that measure very well fall down in their ability to simply reproduce the qualities of music which are evident live. That way, you can enjoy the musical experience as it was recorded. In that regard, the audio reproduction facilitates a musical experience, if you want to use those ambiguous words. Of course, you may not like that musical experience. But you have to separate audio reproduction from subjective evaluation of music. You have to understand that the final evaluation of a system's performance is how well it reproduces this "ambiguous" thing called a musical experience. Measurements are appealing because they are simpler and direct to work with, but unfortunately audio is not that simple. It's no simpler than music-making itself. An accurate audio system is one that reproduces the original experience as closely as possible. An accurate audio system is one that reproduces the input signal accurately so that errors in the output are minimized.

On any given recording, you may like that recording more if there are distortions added, and that's OK since it is your preference. I'm interested in comparing live sound to the reproduction, not simply asking what I like. I'm still waiting for someone to explain which distortion makes analog more lifelike in a way that corresponds to what we actually experience.. for example, which distortion makes harmonic intervals have the right quality, same as live? Just like someone may want to pump up the bass more, or turn up the treble. It may sound better, but it may not be more accurate. What I like and what you like are different. If we use your definition, then an accurate system is simply one that you like. Not much meaning to other people. There are differences in what people listen for. You have the same bind with measurements; when your measurements don't have any correspondance with the patterns that concern me, then your measurements don't have any meaning to me. The idea that audio performance can be reduced to objective measurements is appealing, since it appears to make things simpler, but this is an illusion. Mike |

Actually, a good performer is focused primarily on sound. In practicing, they listen. In performing, they listen. The body movements should be background. This is not to say a performer has a complete understanding of how they sound. They can benefit from hearing a recording of themselves, and James Boyk wrote a whole book about that (To Hear Outselves As Others Hear Us). Nonetheless, a performer knows what sound they intended, and in particular what modulations of that sound were intended (e.g. articulation). Modulations are abstract, in the sense they can be perceived from different perspectives. When system A makes those clear, and system B doesn't, then system A is arguably more accurate. It turns out that for many musicans, system A is analog. I have not seen any reasonable explanation for this other than system A is accurately reproducing the signal patterns which convey these modulations. Mike |

The question is whether or not it is possible to record it and play it back with no percievable distortions. The answer is no. Then the question for me becomes what does the best job of providing the next best thing. how to record it, and how to reproduce it. For now all that we can do well is to record electrical signal produced by microphone. Well no. not even close. There is more to it than just recording the signal off the mic.

OTOH if for some the point isn't the experience then it makes complete sense to brand certain experiences wrong given that they will vary. What do you expect that audio system should reproduce? I want it to reproduce the elements of live music hat gives it it's intrinsic beauty. Of course it's nice if it could get everything right but I do have priorities when it comes to colorations. Just think about what you really want and try to express it in objective terms. (OOPS!!! Did I commit blasphemy?) I think it has been said many times that some of us simply don't know how to quantify such things. one does not need a technical explination for their experiences to actually have those experiences. It's up to the engineers to come up with the objective causes. the good ones actually do this rather than just ignore subjective perceptions. Scott |

Does anybody else understand what it is about? I'll try one more time. Literally you said: I thought the point of audio reproduction was to facilitate a musical experience! An accurate audio system is one that reproduces the original experience as closely as possible. I hope you will agree with me that musical experience depend on many factors and not only on the sound produced by the real musical ensemble, orchestra, singer, etc. For instance it depends on the temperature of the air, if you listen to them being hungry or after good dinner, if you had a quarrel with your girlfriend this day, if you are tired or not, etc., etc. Every time you particular experience will be colored by the factors that you probably even will not recognize consciously. So how you expect recording engineer to capture this experience? For reproducing "original experience" you must capture it first, don't you agree? This is the part of the problem. At reproduction time you will have different musical experiences in different listening sessions anyway. It means that the recording did not capture 'original experience' just because you have differences experiences from the same recording played on the same equipment and probably reproducing absolutely the same sound in both times. And if they are different than one of them is grossly wrong. In this case, is recording engineer at fault? Is digital technology at fault? I just want you to be precise in your thinking and expression of your thinking. That's all. Of course, if all that you are interested is in having a 'meaningful discussion' with another similarly minded subjectivist than it is not me. I have more important things to do in life then have this 'meaningful' talk with you :-) My point of view is that one has a different experience every time when he is listening the same piece of music. Factors affecting him are innumerous. I expect from the recording exact replica of the signal that fed in. And I trust the competently designed gear to do it for me. In real life people hinting me about mystical properties of audio gear that "can be heard, but cannot be measured" most probably want to pick my pocket. Vlad PS. BTW, Harry's 'monadic' listening test suffers from the same problems as "reproduction of original experience". |

Vlad - I respectfully suggest that you have misunderstood my monadic test proposals. I have discussed two he 1) The first, part of a validatin proceedure for abx, carefully matched panels of 200 people for each of two variables. Differences in "listener experience" are thus averaged out over the 200 people, and because the panels are matched on key characteristics, "listening experience" due to these variables are minimized. This type of testing could be done professionally on an occassional basis by a large organization, but is not practical to organize for hobbyists. 2) An extended A vs B test using monadic testing at home. In this case, each listening session is monadically rated. However by doing two pieces of gear, each over many, many trials the fluctuations in "listening experience" due to extraneous variables tends to even out. I hasten to add that this is not a very practical test in any case due to the number of trials and time needed. While in both cases, the listening and ratings are done monadically, the test design itself takes account of and neutralizes "listening experience" variables. Harry |

And if they are different than one of them is grossly wrong. In this case, is recording engineer at fault? Is digital technology at fault? No. But you are missing the point. Just because one's experience is subject to other factors does not render one's experience uterly ranom in nature. The quality of the recording and playback will be the over-riding factor in the long run. that allows us to ignore the other factors that you sem to be quite caught up on. I just want you to be precise in your thinking and expression of your thinking. That's all. Maybe there is a Usnet rec. precise expression group that may facilitate your desires. if your poin is about that and not about audio you are off topic. Of course, if all that you are interested is in having a 'meaningful discussion' with another similarly minded subjectivist than it is not me. I have more important things to do in life then have this 'meaningful' talk with you :-) then get to them. My point of view is that one has a different experience every time when he is listening the same piece of music. Factors affecting him are innumerous. I expect from the recording exact replica of the signal that fed in. Then you will be disappointed. it nver happens. And I trust the competently designed gear to do it for me. Sounds like blind faith. What is objective about that? In real life people hinting me about mystical properties of audio gear that "can be heard, but cannot be measured" most probably want to pick my pocket. Irrelevant. No one is talking about magic here. Vlad PS. BTW, Harry's 'monadic' listening test suffers from the same problems as "reproduction of original experience". Suffers from or enjoys? I think the later.

Modulations are abstract, in the sense they can be perceived from different perspectives. When system A makes those clear, and system B doesn't, then system A is arguably more accurate. It turns out that for many musicans, system A is analog. I have not seen any reasonable explanation for this other than system A is accurately reproducing the signal patterns which convey these modulations. Try finding a reasonable explanation for the preference of many musicians for digital. Here's a clue - personal preference has little to do with accuracy of reproduction. Of course some musician "prefer" digital. And some find it more life like. Same as analog. I think there is a question lurking behind your comments which you have not addressed: If a musician states that system X sounds more like life, how are we to determine whether this perception is based on just liking the sound, or based on an accurate reproduction of the patterns that that particular musician perceives in live sound?

A very good question. The short and easy answer is, we can't. You're talking about a judgment that occurs inside someone's brain. We don't know very much about that sort of thing; psychoacoustics is largely concerned with what sonic information reaches the brain, not what the brain does with it. I think the most we can say is that the latter explanation would be more plausible if system X were more accurate in the technical sense. Here's a question in return: Why should we care? For manufacturers, the key question is, what do consumers prefer? That's the question you ask if you want to maximize sales. It doesn't really matter why they prefer something. If some subset of consumers prefer a system that adds a lot of second harmonic distortion, someone can and will make money selling components that add that distortion. Only if that someone does not honestly advertise said components as having more second order harmonic distortion. Instead he has to use adjectives like "life-like", "musically accurate", "emotionally involving", "magical", and so on. Better yet, get some reviewers to do that. He won't care whether his customers think the sound is more life-like, less life-like, or just "better." So why does it matter WHY someone thinks one system sounds more lifelike than another? Especially when another person may think otherwise? bob |

Well, again accuracy is very much a matter of what one chooses as a reference. I see a fundamnetal problem with choosing an inaudible signal that has already been profoundly affected by a transducer as a reference for playback which is acoustic. so if we really want to mesure accuracy we have to begin and end with an acoustic event and compare that. It may be harder to do but it involves a meaningful reference. Here's a question in return: Why should we care? Because the answers could lead to greater satisfaction for the hobbyists. For manufacturers, the key question is, what do consumers prefer? That's the question you ask if you want to maximize sales. It doesn't really matter why they prefer something.

He won't care whether his customers think the sound is more life-like, less life-like, or just "better." I think you are selling designers and business owners short here. When it comes to excellence passion plays an important part. Put a disinterested designer up against a passionate one that really does care pesonally about the result and my money is on the designer with passion. Indeed one has to share the same passion with a particular market if they are going to compete in that market but that kind of goes without saying. If you are pasionate builder of models out of bottle caps you will have to live with a rather small market. The high end is a cottage industry and those who are passionate live with that market. I have yet to run across the disinterested designer that has succeeded in that market. So why does it matter WHY someone thinks one system sounds more lifelike than another? That is very broad question Scott |

Because the answers could lead to greater satisfaction for the hobbyists. I can think of another reason in addition to that good one: Because investigation could lead to general knowledge about human perception, and that can be useful even outside the audio field. And because the question is so difficult to investigate scientifically, the challenge could lead to new understanding of methods of researching difficult areas of study. And finally because research--pure research--is good for its own sake, though I realize this view is considered pretty outdated in today's market-driven world. |
