What determines "believability of the reproduction illusion"

Thank you sir Jonathan for that info. :cool:

* When re-watching the video I noticed a big console near the rear corner, left rear corner when sitting @ the main spot.

Yes, exactly. We had three different tape machines there... a beautiful Studer A80, a "like new" Otari MX5050 and I forgot what the third one was. Gosh I love tape!
 
I spent a total of at least two hours in the Evolution Acoustics/DarTZeel/Wave Kinetics room over three separate visits (one of which was with Steve, and one of which was with Steve and Mike) and the system did not sound like what I heard on the YouTube.com video clip.
Yes, I would agree that is what is likely the case - so, why? The sound in the clip is poor, for some reason - and it won't be the recording device, the person holding it then moves on to other rooms, and the sound in those is far more agreeable, is showing decent qualities, any problems are far less evident. The camera phone is doing its job, allowing one to compare sound in different rooms, at that precise moment.

Again, why is the sound poor? There could be any number of reasons, including that it was taken very early during the time of the show - the equipment was still settling down, it hadn't been properly sorted yet - a recording is a snapshot in time, unless one knows the full circumstances one can't pass judgement on a precise cause.

That first comment I made was in the context of it reminding me of the many times of entering a room, in the flesh, with expensive gear playing, and the sound literally making me recoil - it was that "awful". I don't immediately think that the components are poor quality; rather that either the people organising it haven't a clue, or that there are major issues with the system that they haven't been able to resolve yet.

The people who set things up are vitally necessary; when I went to the recent Sydney show one exhibitor stood out: they had three rooms, each with completely different brands, styles of speaker, the works; yet the sound in each of these rooms was so markedly superior to nearly everyone else in other rooms - at least one person from that organisation understood what the priorities were, and got the sound humming ...
 
It was also funny when a gentleman showed his face with a smile in front of Mike's phone camera while Mike was videotaping in front of the main gear; TT & all. That was a good move, just great.

That was me video bombing Mike. I could not help myself.

BTW, the glasses I was wearing were made out of recycled records. :)
 
This is one reason why I place no cred in those individuals that are so biased against digital and are so pro analogue.

IMHO, It's very similar to religious fanatics who simply drink the cool aid without reservation. :eek:

Lol, but Frank is pro digital.

Lol, "religious fanatics" ... Frank? That'll be the day! :D

This is great Jonathan; because I could totally relate...and it would be my style too to do something like that. Chapeau! :D ...Great sense of humor.

I think all of us now are beginning to wonder if indeed you really get it. :confused:
 
Steve, I've had to correct that advice so many times now I've lost count - why YouTube are doing this I don't know, but the quality at 720p, and only 720p, is much better - 192 kbps in fact is what you get, almost "twice the quality". This is trivially easy to confirm for most people, just try switching from 480p to 720p and back to 480p on a good quality clip, and the difference should be obvious, the treble and level of detail will change very markedly, unless one's playback setup is very poor.
 
So why Bob would he make such an uninformed, sweeping statement when he had no idea what the source was?

Makes absolutely no sense.
Purely because Peter asked why the sound may have had problems - he suggested that it may be because it was digital source, and IME that is often the case; when some aspect of a system is not right, disturbingly so, then often it's because there is digital circuitry operating in the area, not necessarily actually being the source at that moment!

Steve, the only thing that concerns me with a system is how close the sound is to being convincing, or believable, which is what this thread is about - what david, ddk, calls natural. Anything that detracts from that happening concerns me, irrespective of how competent the rig may be in other aspects - I would much rather listen to a well sorted, low cost setup, than an expensive, ambitious rig with clearly audible issues. Hence my priority is to evaluate whether any particular system is capable of working at a high level at that particular moment, and if it can't then do what is necessary to solve that .
 
The reasons why a system can't perform at a high standard at any particular time are so varied that it is impossible to give simple anwers why ... it's detective work, in every sense of that phrase, to track down underlying causes and often there is a succession of issues, one after the other, which are degrading the sound in more and more subtle ways, as the more obvious weaknesses are 'fixed'. Each step of the process of "debugging" the quality of a rig gets one closer to believable sound - you know you've arrived when, finally, the sound is, well, believable ...
 
One important point: The default for pretty much every consumer phone or camcorder is to have ALC (auto level control) on the microphone input. The SPL in the room is going to have a large effect on the quality of the recording. At the least, it will be almost impossible to get any impression of the dynamics of the system.

Which is a good point. My first, very poor attempts at recording the sound I was getting suffered badly from the recorder having a terrible ALC - it overloaded with obvious clipping at the slightest provocation, and then suffered with poor noise levels if one used distance to get the dynamic range to register cleanly. More recent devices are vastly better it appears, and I now have a decent microphone to pick up what is going on, with a good correlation with what I hear.

SPLs in the room factor in, but here we get back to ASA again - if real musicians were playing in the same room, and the same recorder used to record them, it would be trivially obvious that the sound was "real", over a YouTube clip - in spite of the echoes and other room effects, the qualities that mark out the genuine article would still register clearly to the ear - that's the sort of capability a good system should aim to mimic ...
 
Thanks to Bob, :b, here is a video he posted a link to, in another, related :p thread - https://www.youtube.com/watch?v=JP5x259kTwE. Same main equipment, vastly better sound from the rig this time - again, switch from 480p to 720p, to 480p; should be trivially clear what is lost if not listening at 720p.

Edit: I would dispute the point about the quality of sound picked up by the Nexus phone ... on the 3rd part, https://www.youtube.com/watch?v=PjOq2eElWE0, there are a couple of systems that come across extremely well, including one with tape - I have few quibbles about quality here.

Edit 2: I note that AVshowrooms is now running an overview to Newport, where they praise the EA room; which means that shortly we'll have a cross reference to the quality there, and elsewhere, to compare with the Audio Federation versions - the interesting thing will be to see if common points of behaviour of the systems can be picked up, and assessed to some degree.

Makes absolutely no sense.

Peter asked Frank this: "Frank, what do you think accounts for this? I wonder if it had anything to do with the digital source, which I did not notice the name of. The TT was not playing."

Frank's reply: "Yes, most likely the digital source - ambitious systems can highlight all the negatives of digital playback so easily, and are then impossible to listen to for any length of time."
_________

If it would have been an analog source (which in fact was, tape), it wouldn't have made much difference, I believe, from Frank's reply.

Listen, this ain't the end of the world; we are commenting on comments made from a video. We know that it ain't the real deal but only a very small illusion.
If Frank can see in it something that not everyone see, purely video sound speaking...forget about being there because it's different, it is an analysis from a different perspective, in comparison to other rooms and their own sound from always the Nexus 6's microphone.

To me it's not about even the most remotely illusive music reproduction; it's a simple correlation heard from a phone's mic with one of the guy's own interpretation/analysis.
In that methodology, I would venture (and I did couple times in the past) to have an interpretation too, and by being fully aware, on my overall impression from the sound of a video camera...but not from the Nexus 6 android, more like from Peter's own video camera and microphone(s). And this, purely on the level of a guy watching a video/audio recording of a showroom @ an audio show where music is playing through the speakers in that room and with the source (music recording...analog or digital or both), and the preamp and amp.
This is in no way like being there, but it is permissible to analyse, evaluate, comment, giving a tentative of our overall impression/illusion, and by being fully aware that in real life in our own room @ home, prepared for it...it will always sound totally different than even being there in real life in a dealer room.
When I auditioned speakers in the past @ audio dealer rooms/stores, and that I demo the same speakers in my own various rooms, they always sounded different. Plus! The gear was never exact the same, and neither the audio cables for that matter. :b ...But the room, and the speakers in the room...that's the main sound signature...big big time.

Anyway, I see it as an exercise, not an exorcism. :D ...And I learn in the process too; like it was a tape playing (R-2-R). And the video recording was shot with an android. :b I take the best side of it...the relaxed humor...and not the seriousness.

Additionally, it feels better to have my mind talking about that stuff than all the bad news recently and the very distorted reality of some of our politicians...

Amen. :b

Good comments, Bob ... yes, everything is a flux - a brilliant system can sound awful 5 minutes later, for no apparent reason; and vice versa. The greater the potential of the setup, the more unsettling the sound can be if everything is not in the "zone" - I've battled with this for years, my ears react straight away when some almost trivial aspect is out of kilter - and then it's back to the front lines ... ! ;)

BTW, I've noted that nobody has experienced the mono effect I mentioned earlier, nor detected the change in quality when altering the YouTube settings - or chosen not to comment on the matter. This makes me curious as to how many people 'get it' ...

what I find amusing in this thread is a bunch of subjectivists doubting probably the ultimate subjectivist and asking him to prove it.....go figure
 
People need to keep in mind that I listen to playback from the POV of how close key areas of the sound approach the qualities of being convincing - I have zero interest in listening for how "good" the components are; which of course is the angle that many audio enthusiasts come from. So, I am listening for the presence or absence of certain types of artifacts which will always "wreck" the believability illusion - it's a different way of hearing, so to speak ...

Perhaps it is indeed a different way of hearing that is the case but it seems that you have spent your life chasing your tail and have yet to find Nirvana. I feel sorry for you after I have read many of these posts and your position on certain well established facts that even subjectivists accept.I can honestly say that in my so many years of being involved in this hobby I have never experienced the problems in my system that you have in yours. And then once you find your perfection something else falls apart in your system. You will ever reach nirvana Frank. Something is wrong with that
