The Environmental thread + Conventional (HI-FI) wisdom is almost always invariably wrong

 That is far from my experience, and also that of quite a few DIY Audio members who found that with the almost perfectly measuring amplifier designs from renowned Audio designer Douglas Self, that the sound mainly came from directly between the speakers, but didn't extend past the other sides of them. OR come from behind them.

 

Hi Alex,

 

This is not more related to recording techniques than amplifier & speaker design ?

 Hi Roch

 It can be, but usually the sound should be directly between the front of the drivers of both stereo speakers unless the phase is manipulated at the recording stage. Manipulating Phase can give all kinds of unusual effects, such as with the Olivia Netwton John track " Moth to a Flame" where a simulated moth should be heard doing an anti clockwise circular sweep extending both behind the speakers and behind the listening position if the size of the room is suitable., and your speakers and electronics are good enough. 

 If the room isn't wide enough the sweep will usually sound more like an ellipse with the depth longer than the width.

  

Kind Regards

Alex

 

P.S.

Do you have this track ?

 

Hi Alex,

 

I was not referring to pop commercial recordings, but to some excellent classical music without catastrophic phase manipulations, where practically the speakers disappear and not everything is in the center of the speakers, where the boundaries of the speakers are exceeded in every way .  In jazz these jewels are also sometimes found.

 

My listening room has the appropriate dimensions for the speakers I have.

 

And no, I do not have anything of Olivia's music.

 

Best,

Wait ... In my experience not any single recording / album / etc. appears in the center or let show the position of the speakers. Not any. I am serious. And I play albums at random.

If this happens, something is seriously wrong (and that easily can be a "wrong" USB cable configuration - just saying).

 

I never even thought of a possible variation in "recordings" as such. And I am still serious !

 

The clear exception is: LP playback; All is relative, but that comes across as virtually mono. And btw, I actually never hear vinyl addicts complain about this, while for me it is THE reason not to play vinyl rips.

 

My channel separation is better than 140dB. Maybe that matters (read: suppose you guys have way less channel separation, what actually would you perceive from "worse" recordings ?).

 

I do not want to discourage the audience and not everyone has a USB Lush cable with PN ^ 2F configuration 😉

 

Best,

 The BEST cable is still NO USB cable , with wherever possible the USB device plugged directly into a USB adaptor with the +5V and shield not connected through. :P

 

Maybe there are more effective solutions (albeit a bit risky) like a music brain implant? 😂

 

Best,

Another Indonesia palm oil producer’s propaganda. Although, it may be factual correct but destruction of the forest also destroys the habitats of the wild animals such as rhinos, orangutans and the unique Pygmy elephants

 

 

 

 

This orangutan enjoys coconuts :

Maybe some remember when there was a "global warning (not warming)" as "the cows are cooling the world"?

 

Now we have the answer of the cows:

 

It's true !

I warn certain scientists in residence in AS, I was in the dairy and agricultural industry for at least 40 years of my life, so I have a lot of experience 😂

After the last Ice Age.

 

Of course !  I copy this from Google. Don't know if Democrat Google or the Republican one:

On the Pura Vida Country Google (Where I live) they add:

I was able to watch 54 seconds.  Since she seems to think identity is everything.  You can't be what you can't see.  I can't see me being her.  So with such a stupid, uninformed, divisive approach no need to for me to see more.

So what is this picture supposed to tell us.  Our saviour AOC, in a 1930's business suit, driving a horribly polluting 1930's convertible wearing a monocle.  Picking her teeth with a daisy or is that a sunflower?  Is she supposed to be Hitler or FDR? Maybe it is Colonel Klink.  That fits the childish demeanor of the video (and her). 

 

 

In my country there appears from time to time an even worse mix, young, political, activist, environmentalist and socialist. They attract young people like honey to flies.

 

The problem that I see this as "leaders" is that they do not have practical or quick solutions.

 

But wait a moment, I think there's a solution, last night I saw a movie, Matt Damon's "Downsizing"

I find this cloying presentation disgusting and insulting.  Has nothing to do with my opinion of climate change.  

 

Maybe some little girl will come along and guilt trip her in her old age because the world wasn't made perfect by then.  She'll be all to blame for it, right? Yuck. 

 

Maybe she'll read Scott Adams blog and go learn how to build good nuclear power. 

https://www.scottadamssays.com/2019/09/23/a-message-for-children-about-climate-change/

 

 

 

How dare you Dennis!

 

Maybe you are killing the seed of future Angela Merkel or a ridiculous Emmanuel Macron in a France full of nuclear power plants that supply them with energy.

 

This hysterical girl knows how to exploit human feelings very well and possibly came to the headquarters of the UN swimming, so as not to burn fossil fuel flying in an airplane !!!

So here we are, a bunch of sad, mean, old men mocking an impassioned young woman...always shocked at the pure cowardice of most men.

 

Oh no, I, as an old and evil man, have my own ghosts that scare me, since the big pharma insists on publishing the evils of cholesterol and the world press, without knowledge about it, goes with the flow ...

 

But it seems that fashion is that we live in fear...

 

I have a very clear conscience. I have been a practicing ecologist all my life. Moreover, I am from a generation where there were no disposable blankets or plastic bags and even the milk came in reusable glass bottles ...

 

What I cannot admit is that a girl comes to scold us now and even worse, that the press and many politicians use it as a world leader in global warming. I admit there is a change in the weather and that all efforts made to modify them are valid (if it can be modified) ...

 

I do not believe that "rich men" intend to destroy our planet for selfish purposes for personal gain. If they have become rich, it is not precisely because they are fools ...

Before reading all of this -- remember that the big thing here is POLITICAL POWER, where the energy issues(CO2, warming, etc) are secondary to the ACTUAL goals.  Of course, the 'peons' in the struggle believe in their goal -- that is GOOD.

 

If you remember -- the big thing in the past was GLOBAL COOLING...  Since the scientifically incompetent environmentalists (and the more competent scientists) have learned more, now the terminology is 'warming' or 'change' to avoid terminology  problems in the future.  Frankly, some of our extremists will try to figure out how to blame the sun for the biggest change in global temperatures, and outlaw the sun!!?!?!

 

Where are the growing CO2  problems coming from?  If the US/EU stopped ALL carbon output, the problem is not solved.

 

China would have to start fixing the problem NOW.  So far, the US is doing something (not so much blathering with silly treaties that aren't followed.)  Step by step from dirty Coal (like China & India) to less dirty natural gas (esp if we sell more of it to help others), then another step later on.  Flash cut isn't going to work.

 

A defective treaty that doesn't *really* cover China and India is simple nonsense.  That is the major motivation for the US not to tie itself down, but still decreasing CO2.

 

It is very reasonable and rational to state -- no matter if humanity stops producing any CO2, the global warming will continue.  There are numerous reasons, and the world will also start cooling soon (it is a cycle also.)  Too many variables, and too few/inaccurate models to understand REALLY what is going on.  Of course, there are those tryign to grab political power (the leaders of the environmentalists.)  Most likely they are just as power mad as the evil corrupt capitalists -- they are just too weak to expose themselves yet.

 

It is insane to assume that windmills can replace a quick start natural gas power plant, and I'd suspect that most people in the US won't tolerate losing most of their freedom.  Think about energy storage -- that is a major technology -- think also about exploding Lithium cells.  Do you know why they can explode? -- LOTS of energy storage.   There is the need for HUGE amounts of research...  Do we want our expensive research towards CO2 and other pollution reduction to be stolen by China?  That stuff is called IP.

 

The US/EU are doing lots of research towards CO2 goals, China is building more and more Coal plants.  Our money and resources MUST go where the good (or attempted good) is being done.

Your post is the most successful of all what I have read ...!

One of the better easily accessible articles I've seen on global cooling. 

 

Like this chart of actual temperatures too.  

 

1850-to-2015-temps-no-rss-640x465.png

 

And while it was known earlier that there was a warming trend in data it wasn't linked well to anything until Charles David Keeling began regular atmospheric CO2 measurements in 1958.  Plenty of scientists suspected fossil fuel use would be problematic.   Like this graph too. 

The inexorable rise of carbon dioxide levels in the atmosphere.

 

Now I'm surprised no one has posted how we get to zero emissions starting in 1970 and reaching it in 2050.  I'm all for it, but I'm not seeing the path yet.  

 

I read the article and it leaves me many doubts ...

 

Increase in temperatures of 0.82 Celcius from 1850 to 2015 ...

 

"It is believed" that it is due to the increase in CO2 in the atmosphere ... That is, they are not sure ...

 

On the other hand, where on our planet were these measurements taken?

 

Were the measurements taken in 1850 accurate?

 

Being in the milk business for many years I remember an article published about 30 years ago in a prestigious industry magazine, Hoard's Dairyman, where they said that cows were a danger because their high breath in methane could cool the earth. ..!

 

Maybe we need more cows breathing 🤔
