Send it to Barry Diament...he may want to add it right after the paragraph about one-directional audio cables. :)

I'm not sure if my computer cables are going to him in the right direction?







:cool:
 
Don't get me wrong when you read this, I think this guy is full of crap. To say cables become directional after being broken is just ....:rolleyes:

The first time I saw this was on some cables I bought to hook up my monitors. I didn't pay a premium they where just regular old cables. Why would they put this on?

I did some googling and found this. Does it make any sense to anyone? Could it apply to TRS cables?

--------------------------------------------------
There are some interconnect cables which use two conductors (often a
twisted pair) to carry the signal and the ground return, and have a
separate braid or foil shield. In these cables, the shield is often
connected to the RCA plug shell (and thus to ground) at only one of
the two ends - at the other end it's insulated/isolated from the RCA
plug.

It is believed that in situations where there's strong RF interference
noise present, this separation of the "ground return" and "shield"
function will help reduce the amount of RF interference which can
bleed into the system via the shield. This technique is sometimes
used in laboratory electronics, when taking very-low-level signal
measurements.

So - what do the arrows mean and which end should be plugged in where?
That depends on the manufacturer, on the details of your installation,
and in most cases it makes no difference whatsoever.

Yes...it's true that sometimes you want to "float" the ground only at one specific end...so in that regard the cable should only be connected that one way...but if you remove the connectors, flip them to the opposite ends and float the ground accordingly...you do change the cable's "direction".

What he is saying is more along the lines of the electric flow, after some use, is somehow "burned in" going in a specific direction...and that you shouldn't flip the cable around after that so as not to upset that.

:rolleyes:

Apart from the floated ground scenario...it's just a piece of wire...and the electrons/atoms don't permanently align themselves into a specific direction after usage.

I would love to see him put up some science to back that if it was really true! :D
 
Audio Voodoo, huh?

Ain't no such fuckin' thing, dude. There's good mojo and bad juju but no audio voodoo.

And if you have a lava lamp it cain't fuck with ya' anyway.

Man...audio voodoo is everywhere!!!
Audio voodoo is good.




I guess anything by Behringer employs audio voodoo! :laughings:

Hoffman's forum, they delete your posts or, in some cases, delete the whole thread.

:laughings: Or in some cases, BAN YOU! Reminds me of a certain Pro Audio acoustics forum with a couple of "studio designers" who were the mods. When I confronted them with another point of view regarding QRD's(they use them), they not only removed ALL my posts, but without warning, banned me forever.:mad: Guess they didn't like the public seeing opinions backed by LOGIC. Heres what I posted on thier forum.

The world of studio design abounds with anti-scientific ideas. Clients want cool looking structures that express in physical form a wide range of wacky esoteric ideas. Corrugated diffusers are only one example. Designers and builders serve these emotional needs to the extent their clients have the money to fund its realization, and that's OK with me even if the Pope is a bit miffed. We might as well start bitching about fancy automobiles having little statutes of naked women on the hood because they don't make the car go faster. I say - let the boys have their fun.

But if you want to understand how well a curved plate works as a diffuser, versus how poorly all these silly corrugated surfaces work you can start reading some scientific papers on the subject [a couple of suggested papers are listed below to start you off]. You can also use standard speaker directivity measurement techniques [ground plane measurement method] to explore the matter yourself - it aint rocket surgery.

You will soon find that the corrugated stuff, to the extent it works at all, only works at certain frequency bands. Between these bands are lobes of utter ineffectiveness. Also you will find that at anything other than normal incidence, such diffusive performance as the device do obtain at normal incidence quickly collapses at other angles.

This is why when a professional is serious about needing diffusion [as opposed to just messing with the clients head and providing some eye-candy] they use a curved plate. If you look in a reverb chamber where maximizing diffusion is critical to measurement accuracy, you will not find corrugated diffusers in the corners, you will instead find curved plates. There is a very good reason for that

Geez, Rick. "Silly" corrugated surfaces? No wonder they banned yer ass.

I was kind of hoping that he didn't show up here to try and redeem his errors but he may not show.

I wish he would show up here. The last "Barry" thread I was involved with at Steve Hoffman's forum, I was seriously kicking his butt using logic and science and common sense. He had no credible defense, which of course is why they deleted the entire thread. It was a good thread too, with lots of educational value. I was explaining that only four parameters are needed to define audio gear fidelity - frequency response, noise, distortion, and time-based errors. More detailed explanation here:

Audiophoolery

So Barry comes along and lists some nonsense made-up parameters such as microdynamics. I asked him to define microdynamics as clearly and precisely as possible, and explain how that differed from normal dynamics which of course is just a change in volume. When Barry couldn't give a straight answer they killed the thread. It was both funny and sad at the same time. :D

Awesome paper Ethan.

Cool, guys! Another site for my 'VooDoo' page. ;)

Cheers,

Thanks John. For those who missed it, this hour-long video summarizes all of my current myth-busting and much more:

AES Audio Myths Workshop

This video grew from a presentation I gave last year at the AES show in New York.
