I know it's hard to believe, but we are free to discuss other things, it's only because Merrill's and Jakob's threads on the subject were closed that we are being beaten over the head with this stuff, mainly because Merrill's insults got out of handWe are now all free to discuss other things - game on!
There is plenty of FUD in this thread. One does not need to be paranoid to detect it.
My bias is simple: if conventional psychoacoustics and conventional physics say that some effect is likely to be inaudible then I am not surprised if a blind test finds it to be probably inaudible. I am similarly not surprised if a sighted test finds it to be audible. I am not surprised if a few people find it to be audible in a blind test.
Ah, then you know all there is to know about psychoaoustics or you believe all has been uncovered about phsychoacoustics that you can reference? I would dispute that both of these positions are incorrect (knowing enough about the field to know that all has not yet been uncovered - there are many unanswered questions that have a bearing on this hobby - I also know enough to know that I don't know enough 😛)
You also cite conventional physics in your post not conventional measurements which a number of people here have already contended does not encompass audible differences heard
You accuse me of using a logical trick of the non-provability of a negative but again you are using an excuse to avoid looking at the Foobar ABX test itself & examine it for the rigour that would allow the results to be trusted. It's the same approach many of the ABX defendants adopt - refuse to acknowledge its weaknesses & try to deal with them in a sensible way (insist training is essential prior to testing; include controls which could show the level of false negatives in that test run - positive controls).
Here's a thread of an ABX tests done by a recording engineer who has already established he has an audible preference for files that have been upsampled to 24/192 from the CD - yes a sighted/knowing listening test.
It is an good read for anybody interested in real-world attempts at achieving non-null ABX results.
Look first at how he had to find what difference to listen for (remember he already hears a difference which results in his preference for upsampled version but he hasn't analyzed the music playback in detail to put his finger on exactly what aspect is audibly different enough to be discernible in ABX testing) Note also that this doesn't mean that is the only audible aspect that is different
The difference I hear is NOT tonal quality (I certainly don't claim to hear above 22 kHz). I would describe it as spatial depth, spatial precision, spatial detail. The higher resolution file seems to me to have a dimensional soundstage that is in *slightly* better focus. I have to actively concentrate on NOT looking for freq balance and tonal differences, as those will lead you astray every time. I actively try to visualize the entire soundstage and place every musical element in it. When I do that, I can get the difference. It's *very* easy to drift into mix engineer mode and start listening for timbres--this ruins the series every time. Half the battle is just concentrating on spatial perception ONLY.
Then look at the 'training' he has to do & how ephemeral the training can be
My usual procedure is to warm up--which mainly means getting my focus and concentration together--with about 50-60 individual rounds.
Once I'm warmed up I can replicate the results you see here indefinitely without discarding.
For data collection I prefer as many trials as my subjects will give me, but on these ABX's I've been just stopping whenever I feel like it.
Here I've posted a range of results ranging from 91% confidence to 99.9%
Also note that what warming up means
And how ephemeral the test is
Having trouble "warming up" tonight.
I get the occasional 3/3 or even 4/4, but I can't keep it together for a planned run of 20, confidence always falls apart before I put together a run.
These "all in 192/24" trials are very tough, three may be my limit for a day. I'll try again tomorrow.
I don't really have a good vocabulary for it. I **always** start out listening for tonality, meaning frequency spectra, and it **never** works. Of course, that's how one listens when mixing, creating sound designs, working on guitar technique right or left hand, setting up the amp, on and on. But listening for "differences" in files which do *not* differ tonally is a weird idea to begin with, and these all-192s are even less describable than the earlier 44.1 / 192 comparisons.
Based on the above difficulty of establishing what audible difference to look for which will allow discernment & the difficulty in holding focus on these aspects when doing a Foobar ABX test, I contend that a blind preference test would prove to be a better approach to listening tests .
Hopefully, that was what was meant - I was not challenging his statement as it is what you & I have been saying about blind testing on here but see my post on real world Foobar ABX test & evaluate how much effort & determination is required to overcome the difficulties involve din ABX testing. IMO ABX testing is not suitable for casual testing such as done on audio forums - it's just too difficult to give it a fair chance of having positive results@ mmerrill99,
Imo vacuphile meant the statement in a general sense that it is possible to design a controlled listening test (including the "blind" property) so that an audible difference will be most probably detected. For example by considering all the informations we have collected in this and other threads. 😉

Mainly because you appointed yourself as the Spanish Inquisition, while pretending to want to learn about psychoacoustics - yes I probably got snarky with you as a result & that was my fault but I suspect you or others goaded me & then reported my posts to mods in order to close the thread - see we can all be paranoiac 😀
I have a theory that these people who have learned to listen for small differences have screwed up their simple music listening pleasure to such a degree that they have become bitter towards those who say, "Hey it's good enough for me, stick another record on". As a consequence they want to spoil it for everyone else too, happens all the time. Prove me wrong.
I am one of these people you mention, and it’s the exact opposite in my case; there is so much more pleasure involved not just in listening to/for microdetails in recordings but also the path to unleashing them......just don’t tell me there’s no difference between good enough and fine tuned.
Much like the racer that tunes his own race car/motorcycle......it’s a satisfaction like no other. (That is as long as you don’t suck at it!)😀
Edit: and I’m not bitter at those who say good enough........I mean nattie light is ‘good enough’ for many (there’s no accounting for taste) but you won’t see it in my fridge.

I think you are right.

I’m the kind of guy who will get up and dance to a car alarm. Works for me! 🙂
I’ve also figured out why DF96 doesn’t use emoticons. His haikus of logic are perfect without them. Works for him! 😎

I just received my BenchMark DAC3 from The Upgrade Co. out of Henderson, NV/USA.
David Schulte did the "Signature Edition Upgrade" and RFI/EMI riddance, also.
Nothing changed except everything, every which way was better, clearer, more accurate.

I share the experience and need to control EMI in all forms, I hope that mod works well for you!
I looked around the site a bit and I have to say his comments regarding carpet are way off base. I really do not wish to get into a pi$$ing match with anyone regarding it, but the verified fact of the matter is carpet fibers are extremely low-Q and waste the acoustic energy impinging them in the form of heat.
There are well-established and verified acoustic control techniques which dictate where and how much carpet to use if any, but his explanation of carpet re-radiating has been proven in acoustic testing to be highly imaginary. Based on his explanation a diffuser would be a far greater evil.

You are wrong in so many ways that it's impossible to answer you - anyway you have demonstrated in the past that you don't want to learn anything so why would anyone botherI have a theory that these people who have learned to listen for small differences have screwed up their simple music listening pleasure to such a degree that they have become bitter towards those who say, "Hey it's good enough for me, stick another record on".

Exactly so, MM. What many fail to understand is that listening specifically to how a system reproduces details is a different way of listening to normal & that those details (as long as they are not false detail) make for a more realistic portrayal of an actual musical event even when not focused on them specifically - they are just one sign that the playback system is doing something more correct in its replay - it is likely not the only notable difference - often better perceived timing, more solidity & more layering to the soundstage & othersI am one of these people you mention, and it’s the exact opposite in my case; there is so much more pleasure involved not just in listening to/for microdetails in recordings but also the path to unleashing them......just don’t tell me there’s no difference between good enough and fine tuned.

It's hard to describe....so I won't. You'll know when you reach yours, it will be something like, veils lifted etc etc blah blah.I do sometimes wonder from your posts what exactly your audio nirvana consists of? 😀 YouTube

Nothing has changed in audio replay since the 1950s - it was perfect then, right?
Yes, I think you are right too. 😀I think you are right.

We don't get many car alarms here, and I've yet to see let alone hear a house alarm 🙂 We get the odd siren which a couple of dogs love singing along to.
It's a bit cooler here today, trying to rain...not very successfully

His iPhone, - did you not know this is the top-of-the-mountain, the revelation awaiting all.
Try. I've learned a lot, here and there, I just don't feel the need to tell you about itYou are wrong in so many ways that it's impossible to answer you - anyway you have demonstrated in the past that you don't want to learn anything so why would anyone bother
Strange deduction? Has the forum been going that long?Nothing has changed in audio replay since the 1950s - it was perfect then, right?

What makes you think I haven’t reached mine?
I think most of my issues stem from seeing too many of the old old BASF commercials........YouTube

Nah, I've stopped bothering to answer your questions as the questions themselves show you have learned nothing - you are just an agitator (others would say troll).
Actually calling me an agitator is trollish. Asking questions, expressing opinions, not so much
So does anybody want to discuss the real-world report of a successful ABX test & what it takes to obtain a positive result just so his already established sighted/knowledge preference for 24/192 could be 'proven' to others.
Ha had no difficulty in sighted listening coming to his preference, no listening to minute details or training or incessant replay of the same piece of a track, just allowed for a more holistic impression of the music portrayed by the replay system.
The need to find the specific tell that will allow an audible difference to be identified between A & B is what ABX testing imposes on the listener. Finding this & holding focus on this during testing is the main difficulty with Foobar ABX, IMO.
Yea, I know there will be those who say that this type of listening is not imposed by ABX one can listen holistically too. Yea, you can listen in any way you want over any time period you want but show me a positive result for Foobar ABX that used such a style of listening.
Face it, the inability to acquire a positive Foobar ABX result is a failure in the listener to overcome the massive barriers & skewedness that the test has for returning a null result. The casualness with which it is bandied about as some sort of 'proof' on audio forums is testament to how useful a tool of propaganda it has become for the group that cry "prove it" at any posted report from people who report their genuine impressions.
The most equitable & balanced approach, IMO is to treat both sighted listening & blind listening on audio forums as a bit of fun but there are still some ......
