The Purpose of Audio Reproduction


fas42

Time to crack this back open again, 😄.

 

Yes, what's the point? There could be a zillion answers, but my answer is to be true to the contents of a recording ... I was going to post this to that unloved thread, now gone to zombie land, but I'll do it here, instead,

 

 

Bit of a mess, eh? And, this is the remaster, from 2015!! - I've got it on a double CD from 1998 - a low cost release - sludgy, plus? ... You bet!

 

What should a system do to, for this? In my book, absolutely nothing more than the best job possible to being accurate to the data - now, what I'm getting at the moment is not elimination of the sludge - but is a realistic pickup of what was heard in that club. The reproduction, currently, is not the best it could be - my active speakers still need to be refined more; which will gain me greater clarity, a better connection to the musicians doing their thing ... this sort of track is very helpful in making it clear where the shortfalls are.

Audiophiles do come in different flavours: for example, there are those who are certain that a high percentage of recordings are inferior, and hence will pursue a special version of some album; or those who enjoy seasoning what they hear by adjusting distortion generating areas of their rigs - the "tube rolling" thing. Which are perfectly good hobbies, in their own right.

Fair enough, but do you understand that the above relates to personal preferences, which is a different to individuals actually hearing differently?

 

As an example, two people might hear sounds very differently but both like jazz.

 

To other individuals might hear sounds identically, but one likes classical music, the other EDM.

I think Frank feels he is the only one who can hear things this way and he is right. But his explanations are so full of pseudo-science and non-science ideas, it is a cult of one.

Yes, it started that way when he joined this site in 2017... and 2,418 days and 12,425 posts later... it remains that way.

Yes, missing the point is bad. Although you did go on to say:

 

Luckily, I skipped the whole jitter craze ... to this day I couldn't give a stuff about jitter numbers - and that hasn't got in the way of the SQ I look for.

 

Because, "to that day", I had no evidence that jitter was causing an issue - in the systems I was playing with, I always achieved, at times, a standard which was satisfactory. Would the quality have been even better had I looked at improving clock behaviour? Possibly, but the fiddling required just was not enough motivation - as a side note, I did indeed purchase a quartz crystal with exceptional low phase noise, from a local manufacturer, to investigate that side of things - but like many things in life, it moved down to the bottom of the drawer ... where it still remains, :).

Yet the Dutch & Dutch speakers use DSP to adapt its behaviour to the specific requirements of the room using their "RoomMatching" technology. Mindful that these speakers provided the sound that you are looking for, does this not make you rethink that DSP / room correction technology used wisely might be a good thing after all?

 

DSP to optimise other characteristics is a fine thing to have - but is not essential. Simply put, those speakers distorted less than any other system at the show - not by a big margin, but enough to point out how other setups still showed flaws, at times. As an example, I specifically asked for some opera, with female voices; at room filling levels this was flawless; as good as I could wished for.

 

Now, you might think a chunk of DSP thrown in can magically make female operatic reproduction less ugly than it often is ... but I don't :).

I sometimes think about what it must have been like for a medieval soldier going into battle. His side is horribly outnumbered, he does not have the best weapons, he does not have the armour that his rivals sport. Yet he still goes in and fights for his cause.

 

I feel a bit like this going up against Frank on an audio forum, but at least here I am not likely to have my gizzards sliced open.

 

Quite easy to "fight back" ... I regularly mention tracks that are a good test for playback integrity; all one has to is state that your system has no issues playing such tracks ... but a typical reaction is, "How can you listen to that 'orrible stuff!" - which, says it all, ^_^.

Again, the simplest way to describe what I'm after is the "Is it as good as real?" test - behind a curtain, a drum kit, and an audio system: either a real drummer is firing up, or the rig is playing back a recorded session on those drums - which is it, this time? The closer it gets to being impossible to tell, the happier I am. And for those who think such is well out of reach, the previous audio show, which showed a less than OK overall standard had one outstanding exception - I asked to hear a drum solo track, and kept pushing the demonstrator to up the volume ... and that rig delivered. Even at 'thunderous' levels, no flaws showed in the reproduction ...

 

IOW, accuracy is the name of the game, for me.

You keep wanting to ignore the fact that this has been an interest of mine for nearly 40 years - why can a system 'nail' the SQ at times; and what stops it happening the rest of the time? Yes, accuracy is key - but if the "accuracy" that most audio people are so focused on is all that matters, then why do those systems that have that type of accuracy still fail to deliver? Or even sound awful?

 

The ear/brain compensates for all sorts of shortcoming, if the right things are in order - there's a whole, ummm, "pseudo-science" investigating this very concept, which started from the ideas of this chap, https://en.wikipedia.org/wiki/Albert_Bregman. But the normal audio world just wants to ignore these areas of research ...

This is a hilarious response - only I am aware that major chunks of what's on the track are just not audible ... could it, just possibly be, that other people have never heard those missing bits; because, they have never heard it replayed well enough - so to them, "What's your problem??! ... hmmm?

Did you know there was an expert and he studied for 40 years to prove the world was flat. He built a rocket to prove that he was right and to take pictures, etc. He blew himself up because he wasn't an expert on Rocket design, but he THOUGHT he was. Doesn't matter how long you study, if your premise is built on fallacy, all that time is wasted. A true intellectual would see the actual facts and understand they were wrong. They do not double down on their nonsense like you do. Your behavior is the definition of a cult member. I do that everyday in my job as I have worked as a research scientist for 38 years. I know what I am talking about. Nothing you do is scientifically sound or valid. 

 

Sorry Frank, you are just deluded.

 

Sorry about the bluntness but keep tilting that windmill if it makes you happy. You are not convincing anyone.

 

 

 

So, guess who is certain that some area of research is nonsense ... because he suspects it could impact some of his personal ideas of "how things work"... ?

I was referring to this part of your post:

 

 

The fact that you're the only I've ever heard say that almost all high-end equipment is crap tells me everything I need to know about your belief system. 

 

My "belief system" is informed by the fact that a single "high-end" rig, the one I just noted with regard to drum kits, achieved good accuracy - I don't bother trying with other 'contenders', because they show too many flaws, with far less onerous tests.

 

I'm sorry, but if something claims to be superior, because, for example, it's expensive - but it's trivially easy to catch it out, demonstrate that it's obviously flawed in some area of its behaviour ... do you think such is worth giving a big tick to?

Again, why are you the only one noticing that all of this equipment is flawed?

 

And, if you are only one who hears these flaws, why should anyone else care?

Don't worry, everyone notices the flaws - but it's swept under the carpet with comments like,"Gee, <manufacturer> has such a distinct signature, with everything they do", or, "Garbage In, Garbage Out" - that's a popular one! :P - or, "They really need to sort out the room acoustics, here!", or, "Why do they put a  Big/Small system in a Small/Big room?", or, "Well, that's horns for you!" - and so on ...

 

People should care, because substandard playback continues to be the norm - people note how inferior the presentation is with visual media only a generation or so old; the same should be so with audio media ...

 

Which reminds me, literally an item on today's morning TV; some new music album that's stirred strong interest - and a clip of Keanu Reeves saying something like, "Gee, I really like the digital version of that album - I can't wait to get it on LP!!" ... oh ... dear ...

Well, I really understand the groove of that track ... which, for me, makes up for everything else, 👍.

 

Dunno why it's so difficult for people - an accurate system makes for magic; if you don't get magic, it ain't accurate ... I wouldn't be happy with the rig of our good friend, @Audiophile Neuroscience, since it makes his Rolling Stones albums sound rotten :D - that's a reach too far, for my poor sensitive, 'snowflake' ears 9_9.

BECAUSE AUDIO IS NOT MAGIC, Frank. If you make a bad recording sound good, your system IS NOT ACCURATE.

 

Garbage in, garbage out - that is accurate.

There is no tag on the CD cover that says, "Bad recording!" - the only way you decide whether it is or not is by listening to it, usually on your own system. And you have no way of knowing how accurate that playback system is, apart from some minimal measurement figures that barely scratch the surface ...

 

Which leads to a, true, story I have probably pointed to before: the sales rep of AVOmeter, the finest multimeter of the day, wanted to convince a concern that they should buy an "accurate!" device by showing how everything they used was all over the place. Trouble was, all the company's measuring devices agreed with each other, and the reading was significantly different from that of the AVOmeter! By chance, just prior to the visit a concerted effort was made to calibrate all the in house units against what they felt was the best - and so the poor sales rep ended up deeply shaken by his unit's lacklustre showing ; they never let on what was the true situation ^_^.

 

So, where is the AVOmeter, properly established as a good reference, that decides how garbagy the recording is, hmmm ... ?
