Audio Blind Testing

[Ralf11]

sandman - you better ask yourself if you are the victim or the crime

 

 

 

I'll avoid commentary on the incredible irony of your last paragraph

[Ralf11]

 

A multi-miked recording using a forest of microphones

 

and then a spherical array of boomboxes with you at the center

 

then tuned to create the allusion of reality

 

You have to admire fas's genius

[Ralf11]

I say 2 crossed mics and just ride the gain controls...

[Ralf11]

I can make it harder - just capture any version of the original soundfield, and do the corrections by altering the processing in the brain, not by the listener (who will have to work hard to do it internally), but by the experimenter.

[Ralf11]

only for an Australian

To localize sound you need ILD and ITD. Your example applies to mono signal because when the head is held steady both signals arrive your ears at same level and at same time thus making localization impossible and you can  place the sound anywhere along the line. However, your visual clue also would play a role and it is possible for you to imagine a location,IMO.

 

except that human ears are usually offset - just a little tho; not like an owl's

 

IIRC, the ear canals also differ slightly and there is some phase detection going on perhaps based on arrival times

 

and... shading effects of the head also allow some localization

[Ralf11]

My point is that because your 2 ears are not identical you will be better at localization

[Ralf11]

there are some studies out there if you want to search for them

 

(nothing in my memory bank - that has pointers active right now tho...)

He only writes in vague generalities, never with anything specific. What equipment does he use in order to get this "perfect" recreation of the sound field? How does he manage to get this great imaging, even from multi-track, multi-miked recordings that don't have any real image, just a bunch of pan-potted instruments artificially lined up from right-to-left? What is this perfect amplifier he has that's so much better than the ones everyone else here is using? He never says. What are we to glean from this lack of disclosure? 

 

I glean that he is like GUTB

Who pushed Alex' REPEAT button?

 

Who???

 

 

 

The crazy seems to come on at certain times of day - not sure why 

 

 

Anyone who claims that double blind testing is a "silly game" is extremely ignorant and not an audiophile.  Maybe an audiofool; maybe an anti-VAXer...

[Ralf11]

covfefe vaccinations?

 

(it was just an analogy...)

[Ralf11]

Buying or making good equipment is a blind numbing waste of time for Audiophiles who just want to listen to music for their enjoyment.

 

Most idiots don't give a damn for the continuing demands by scientists to validate every medicine  they take.

 

 If you feel the need to avoid valid testing, science and engineering all the time, then perhaps you are a member of the wrong forum ?  Or your drugs are not working well.

 Unless you have anything better than insults and sarcastic remarks to make, why don't you leave replies to others who are able to make On Topic replies ? 

It would appear that you get a kick out of deliberately trying to disrupt all threads where you don't agree with those who have opposing views to your own.  

 

 

I do indeed 'disrupt' idiocy by pointing out or making some fun of it.  That applies to audio (where consumers can be damaged by such idiotic remarks) as well as things with worse outcomes.

 

You really need to calm down and behave yourself.

Who died and left you in charge?

 

 

Don't forget that the Audio Ayatollah has issued a Fatwah against the use of science

 

He did, however, make one point that is good to the extent it is relevant:

- some audio gear has gotten better since some tests were done

- but this is only relevant for specific gear compared, and it seems he did not read the several studies showing the importance of confirmation bias in general

[Ralf11]

this thread is about blind testing

 

post your rants elsewhere, please

I own a hammer, saw, and tape measure. Even know how to use 'em. Doesn't make me a carpenter. 

 

 

Exactly.  He seems to think that use of certain instruments makes someone a scientist.

 

Sad.

 I mentioned the gear that I still own, and use, in  part of a reply to Ralf11 who accused me of not using any scientific methodology.

 

 

 

....and there we have it

 

I rest my case.

Scientists are STILL unable to agree on whether Global Warming is part of a long term Climatic cycle, or whether it is man made, and requires human intervention to reverse it !

 

 

 

Sad.

It's even sadder when arguably the most powerful nation on earth ,which is committed to Freedom and quality of life,  is virtually the only country not to commit to reducing the effects of man made emissions, and excesses, including deforestation.

Even if the main problem eventually turns out to be due to a natural cycle, doing so may help to reduce the harm to mankind, and other species a little . 

Recently in Sydney , and elsewhere in N.S.W. we saw several colonies of Bats lose hundreds of mainly younger bats who had their brains fried by the excessive heat, and Wild Life people trying to save others by wrapping the distressed bats in wet towels, and spraying water on them.

 

Perhaps it's time we tried to get away from the "Greed is Good" philosophy of major corporations, including the Banking sector ?

 

all true, but don't blame me for the Groper in Chief

 

my rxn was to your incorrect claim that scientists differ on whether climate change and global warming is a natural cycle - it isn't; they don't

 

What we are seeing today is warming with about a decade lag from CO2 emissions - the lag times are asymmetric, and if CO2 emissions went to zero tomorrow at 8 am, atmospheric levels (and consequent warming) would last centuries to millennia

 

Drumfk's minions have not removed this web site yet:

https://climate.nasa.gov/evidence/

 

 

[Ralf11]

name the climate scientists, please

 

 

the Kochs hired a physicist to "investigate" global warming a few years ago - he was a bit out of the area but skeptical of the claims - after he looked into it he changed his mind

 

the forest fires are human caused (nearly all ignition events in the US are from humans) and exacerbated by climate change

[Ralf11]

maybe we can give him a bye since he is a geologist, not a climate scientist

 

also his views may have changed in the last 20 years?  (book is 1999)

 

[Ralf11]

I suspect we could find some music where few could tell mp3 from Redbook, or other

 

Interesting thought re age - certainly possible - would make a nice gerontology grant appl. to NIH...

[Ralf11]

Yes, I know - mine was damaged at about age 12 - lightning struck a tree next to me on a Boy Scoot camping trip, creating a notch hearing loss at 4 kHz.

 

Unfortunately, it did NOT prevent me from hearing the differences between expensive and very expensive components...

 

You are right about the teens.  maybe hearing loss will make them into visual artists...
