How Much is Undoubtedly Too Much?

My neighbors most likely don't want to overhear my jamgrass in multichannel audio. I'm not gonna say those are insurmountable.
All it takes is the desire and the money, plus maybe the room to do it.

Whether 2ch or 15, what your talking about is living with the neighbors and that's a issue that many have,
it's simply a matter of SPL - loudness. Your neighbors likely won't want to hear your "jamgrass" no matter how many speakers you have.
If your being restricted by possible disturbance issues, that's something you have to find your own answer to.
I struggled with those issues for a bunch of years till I finally found a way to purchase my own home where adjoining neighbors
were no longer a problem. There's not a hell of a lot of other options open.
 
Doesn’t answer what I was speaking to and also avoids the prospect of changing all two channel recordings to surround sound via up-mixing as your post had implied was fine.
Yea, it kind of is. It's about whether the tonal mods or upsampling are easily reversed to a transparent state or not.

Headphones. I visited the Dolby Atmos "demo site" and listened to a couple of tunes in Dolby Atmos. I'd say it shows promise. I'll have to wait a while until it becomes the industry norm to hear the kinds of music I like in it though.

It is the industry norm, at least for current immersive listening, it will be a long time before something replaces it.
 
Multichannel has been around how long? Twenty years or more? It hasn't happened yet.
Well, three channel stereo was the way two-channel "stereo" was recorded in the second half of the 1950s.

Isn't it interesting that Ol' Blue Eyes is rockin' a Mac preamp -- but a Fisher tuner?

ahem.
In terms of multichannel...
"Quad" :facepalm: dates back to ca. 1970.

So...the timeline on multichannel "taking over" is pretty much on par with viable nuclear fusion power.
:cool:

PS Yeah, @Robin L, I wasn't thinking about Fantasia, as it was a special case. The RCA 845 amplifiers used for audio in the limited number of theaters playing Fantasia in its original release were (are) amazing, though. 1600 VDC on the plates. That's what I'm talkin' about! :cool:

I think I should do more digging - I suspect there are other films that deployed multi-channel sound. Cinerama in the Fifties had a surround sound system using seven channels. I can't find documentation right now, but Acoustic Research and/or Bell Labs had a surround system using something like 16 speakers back in the Seventies. I remember watching/hearing 2001 when it first came out with some sort of surround sound array. As far as I can tell, surround sound starts with Movies then trickles down to home audio gear.
 
I was talking on the list where the speakers are graded (with the best being 7.3 or something like that, KEF probably. It's not only Amir's reviews, but I thought it was representative of ASR testing and taking into consideration the price.
The 7.3 is a "preference score" created by Harman and computed entirely from measurements. It does not take price into account. For more details see the "readme" section here:

 
Sonic neutrality is a good starting point, in the same way it may be wise to first taste your food before adding additional seasonings. This morning, I sprinkled some chili crunch onto my breakfast burrito, and it was heavenly, but I don't think I'll do the same to my tiramisu.

Sure that’s cool.

Though it may be noted, that still seems to be on the side of a preference or taste based approach. You are deciding how to listen to each track based on whether you like how it sounds or not, and altering the sound when it’s not pleasing enough for you.

Which again, nothing wrong with that.
 
It would seem odd to care that much about accuracy right up until it’s actually coming out of your loudspeakers, and then you just change everything like putting a big filter over it (e.g. put a big smile eq setting, or up mix 2 channel to a different format).
There are different types of “accuracy” which I consider them each individually. I don’t know about a right or wrong, it’s just how I think about it.

Some types of distortion are destructive to the source/signal and these are the worst. A loud room hurts S/N ratio. Nobody wants 60 Hz hum introduced into their system. In general, high fidelity pursues low noise. There is a real loss the information contained in the recording.

Non-destructive alteration preserves all of the information. A perfectly applied spectral tilt for example could be recorded and transformed back to the original recording. No information loss.

For my ideal system I want to extract all the goodness possessed in a recording. If there are details I want to hear them. If there is soundstage I want to sense it.

“Accurate” reproduction might contribute to achieving this goal, but it’s not something I care a lot about for its own sake - preserving the artistic intent or some such. I just want it to sound good.

ok thanks for the clarification!
 
This thread shows the usual two goals in audio: “accurate reproduction of artist intent” and “using this accuracy as a base to tailor sound to personal enjoyment”

A realisation I had reading this thread is that upmixing Stereo to Spatial Audio is both at the same time.

On the one hand it’s no different than placing absorbers and diffusers in your room, but with more freedom, to decide what sound hits you from where and when. It may (depending on the quality of the upmix algorithm) transform your living room into the opera house or mastering studio.

On the hand, because there are still competing standards (Dolby, DTS, Apple, IBUsomething), variations in those (7 to 21 speakers?), and different upmix algorithms, it is also a subjective matter of preference and enjoyment. Even if you REW the daylight out of your system.

It's different for listening to actual Spatial mixes (not upmixing), which is simply true to the artist intent.

Perhaps to the benefit of no one I wanted to share this realisation. :p
 
Doesn’t answer what I was speaking to

You love relitigating the same arguments over and over with maximum verbosity but no gain in information content, and you're always demanding people address whatever tedious point you're making again for the 100th time. Tiresome.

and also avoids the prospect of changing all two channel recordings to surround sound via up-mixing as your post had implied was fine.

//

It is 'fine'. I do it. I wouldn't if it didn't sound 'fine'. (Need I add 'to me', are readers that obtuse?)

And as it's been pointed out at tiresome length -- golly, there's that word again, you do seem to evoke it -- if it sounds bad, I can turn it off. I can turn DSP room correction off too,. Back in the day, I could set all the tone controls to "0" as well.

But why would I, if it sounds better to me to have them on? Obviously I'm deciding what the audio *should* sound like. I'm not making you listen to it.

What I don't want is gear that 'turns on' some sort of distortion that I can't turn off. I don't want to have to check out multiple units that have their own inherent distortions, to see/hear which flavor I might like to live with best. What a massively inefficient method (unless you actually *enjoy* it, in which case it's ...fine)

It's already the case with speakers, and that's bad enough. I think turntables are fetish toys, but hey, knock yourself out..

I'll remind you of the tiresomely repeated fact that you'll never hear exactly what the mix engineer heard, and, for an acoustic event at least, what's captured by the recording engineer will never 100% reproduce the event (for other recordings, there may be no single 'event', it's a collage of events, and may not have ever existed in acoustic space). So what exactly are you chasing? A pleasant illusion of 'reality'? What if multichannel -- including synthetic -- gives that better?

//

Everything above, between the // marks -- you've heard (read) ALL OF THAT before. All of it. We all have, here.
And yet you persist in insisting it be regurgitated.

How about just SingTFU about it for awhile?

But wait, before you do that (ha, is if) -- you elided my advice to go bend Floyd Toole's ear about upmixing.

Please, please do go tell him IT'S NOT FINE. Tell him it's antithetical to high fidelity'. Save his soul. I've got popcorn.

What if an upmixed rendition of a favorite two-channel release, sounds not only better than the same in two-channel, but better than a new surround mix of same?

For that matter, what if a surround mix sounds better downmixed to 2 channel?

Where lies the 'fault'?
 
You seem to be confused that I’m arguing against your right to alter the sound however you want. I’m not.

What I’m doing is pointing out that you seem to be expressing an opinion as if you are
“ letting us in on the obvious facts” about the nature of hi-fi equipment and the goals associated. But this is far from obvious.

Remember, after you opined that converting two channel to multi channel is the better way to go, Levimax pointed out:

“If Stereo converted to MC is truly "better" then that means "Hi-Fi" is not about trying to "reproducing the source" as accurately as possible rather it is about "reprocessing" the source to be as "pleasing" as possible.”

To which you suggested that has always obviously being the case.

But that’s far from obviously the case. The idea that hi-fi is ultimately (in terms of what the listener ends up hearing ) about reprocessing the signal to taste does not actually fit well with many of the stated historical goals of those developing hi-fi equipment, and such a view has been contested here for years by other people who care about high Fidelity.

Once again: The reason so many people care that their speakers are accurate, and even go to lengths with room treatment or DSP, is to maintain as much as possible, the accuracy of the signal the listener actually hears.

If someone for instance had a benchmark amplification and DAC, but chose Zu audio loudspeakers, it would be seen as strange if that person claimed to be interested in high Fidelity sound. Why? Because whatever the Fidelity of the signal leading up to the speakers, he has chosen speakers with a ragged frequency response that will impose that response on the signal, rather than reproduce it more accurately. Right?

Likewise, if you substituted much more accurate Revel loudspeakers in the same system, it would make sense to say this better fits the ideal of a high Fidelity system.

However, if someone EQ’d in a ragged frequency response, like that of the Zu loudspeakers, then it no longer matters that this person is using Revel speakers. Just as if Zu speakers had been used, this system is no longer producing what most people would think of as high Fidelity sound.

That’s because “ high Fidelity” is often aimed at the actual sound the listener ends up hearing, and not on some of lip service to the idea that “ well, most of the chain is transparent” (even if I’ve decided to totally impose my own colorations in the end result).

In fact, in principal the proposed solution to the circle of confusion is that there would be a consistency in terms of accurate equipment In both the creation of recordings and playback of those recordings in the consumers home, that we would experience “ Hi Fidelity” to what the artist created in their artistic environment. And that would, of course imply one isn’t just totally colouring the sound differently at the last moment.

So again, I’m not saying you have no right to change the sound whoever you want. What I’m pointing out is that your breezy dismissal of Levimax’s point isn’t so obvious and clearcut as you suggest.

With that point out-of-the-way, let’s get to your dismissal of my other point about where one decides to colour the sound to taste…

if it sounds bad, I can turn it off. I can turn DSP room correction off too,. Back in the day, I could set all the tone controls to "0" as well.
But why would I, if it sounds better to me to have them on? Obviously I'm deciding what the audio *should* sound like.

Exactly.

And my point is that once you start doing that, then appealing to what hi-fi equipment
“ should be doing” seems to leave the question “why? If you were just going to alter the sound to taste anyway.” And then if you are doing that with your “ hi-fi” system, how can you dismiss other ways of colouring the sound? You seem to have undermined the point of hi-fi systems to begin with. If someone is inserting an equalizer into the chain, or tone controls, or up mixing, they have decided not to pass on the signal with high Fidelity. They have left a piece of equipment reliably altering the signal to their taste.

Inserting something like a tube amplifier that produces audible distribution could be playing the same role. You’d just be choosing to alter the signal with a different piece of equipment in the amplification chain.

You suggested this logic is “ laughable” but without actually explaining why.

What I don't want is gear that 'turns on' some sort of distortion that I can't turn off.

OK, so that’s what you don’t want. That’s your opinion that’s your goal.

But if, as you’ve stated, the ultimate goal hi-fi gear is to arrange the sound to one taste, then it seems we’ve actually left the realm of traditional goals of high Fidelity. In which case you can’t crow about your decision being the reasonable one, and that it is “ laughable” that this allows for colouring the sound however one wants.
This is where you land once you have abandoned certain ideas about high fidelity.

Please, please do go tell him IT'S NOT FINE. Tell him it's antithetical to high fidelity'. Save his soul. I've got popcorn.

Red herring.

How about just SingTFU about it for awhile?

May I suggest perhaps a more comfortable mattress?

Maybe a New pillow?

Red herring.

Alas, it seems I won't get to see you emit these obviously dearly held beliefs about what's 'logical' and what lies 'within the realm of traditional goals of high Fidelity' to another who enjoys upmixing, but who, unlike me, happens to be an actual authority on home audio and the science thereof.

Won't you indulge me? It's the only exchange that I (and I have no doubt others too) would be actually interested to read.

Yeah, that was a weird retort to my assertion that mch is the SOTA these days. Multichannel will be too loud? Who says it has to be?

Loud, low bass is what's going to generate the most complaints, for any channel number. His neighbors might well hate his two-channel 'jamgrass'* already. It depends on how loud he plays it, and to a big extent, how much bass it pumps out.


*Just reading the word, I already hate it.

Not in mine. there’s nothing wrong at all of course with stating that optimized multichannel achieves SOTA results at this point.

If you think I’m arguing against that you are still confused, I guess.

But then again, it’s not that surprising you’d remain confused if…

…. You choose to ignore reading what the other person writes.

Indulge you how? What are you suggesting?
Do you think I’m arguing that neither you nor Floyd Toole add to enjoy upmixing 2channel too surround? That would be absurd. I upmix stereo to surround fairly often myself and love it.

As to my actual arguments: do you think Floyd Toole would actually disagree with examples such as the ones I gave? That for instance, even taking an accurate loudspeaker but using an EQ to put the frequency response all out of whack, would amount to altering the fidelity of the signal? And if you are doing that, it has implications for one’s approach to “hi-fidelity?” What are you actually objecting to? I guess you don’t know because you don’t bother reading what I write.


Have you considered decaf coffee?

Meditation? ;-)

OMG, stop.

You led with a mischaracterization of what I 'opined' about. And then your wheel spun on and on, into the well-trodden (ruts the size of the Grand Canyon) realm of 'what is high fidelity?'

Whatevs.

Two-channel audio is a mature technology. It is not the state of the art in audio anymore, and hasn't been for awhile. THAT was/is the point that is pertinent to this thread as per the OP's first post : "[H]ow cheap is the cheapest state of the art system one can aspire to?".

If I don't get to see you debate your philosophy of 'high fidelity' with Floyd Toole, there's little in your replies new or interesting or entertaining enough to respond to.
