Yes a POLARITY STANDARD does exist...

In this post, clarkjohnsen asserts that:

To repeat: No conventions exist to make sure that you are listening
in Absolute Polarity. Neither the AES, nor the RIAA, nor the DIN,
nor the specialist press has lifted a finger to establish or even
suggest a standard for recordings or for playback equipment. Thus
it's still up to you yourself, to achieve better sound for free.



This is wrong: it exists an AES standard:

AES26-2001
Revision of AES26-1995

AES recommended practice for professional audio interconnections.
Conservation of the polarity of audio signals

The fun thing is that we yet had this discussion in late august, and I gave the same information to ... the same people. See here.

Then I was objected that
"An electrical standard is not enough",

that
"It doesn't transfer to tapes, LPs or CDs.
For instance, does a stylus excursion to the outside denote a positive-going or a negative-going electrical signal? The AES is silent.../..."

See here Clark's answer


So I made my home work, read thoroughly the standard, and I could answer to each objected point.

In a few words, AES26 is not just an electrical standard but also addresses stylus' speed vector for vinyls, direction of magnetization for tapes, and absolute pressure for acoustical drivers.
See detailled answer here


Unhappily, I got no answer to that one, and the thread died.

Funny to see it again having a hard-on.
So, again again, who is wrong?

And again, yes, a polarity standard does exist, for stylus, tapes, CDs, drivers and everything that sounds through electrical connections.

Oh, I got it freely on AES site, you should do too, seems it is public domain.

I won't address in my post the issue of polarity being audible or not, nor the phenomenon of selective lapse of memory ;-)
