Any proof that it affects signals...
Nope didn't think so, doesn't affect even more critical analogue signals, why should it affect audio signals.😕
Unless you play your own music acoustically, your signal passes through at least several tens of solder joint, if not hundreds....and thats not counting IC cables..
Your intuition is sound. Each solder joint or other dissimilar metals connection in the signal path, or even temperature variation on a conductor, produces thermoelectric voltages (Peltier-Seebeck effect) that can be on the order of millivolts at room temperature. This is the principle of thermocouple operation. Cold welding of connections (crimp lugs, wire wrap) is one way to minimize this.

Some people like mysteries. They have to believe that there is some deep truth about pieces of wire forming trivial potential dividers (also known as audio interconnects) which has escaped conventional science. Hence they postulate skin effect, dislocations, interfaces (at solder joints or between crystals), phonons etc. etc. - in most cases showing a knowledge of words but not their meanings. Some even claim to measure these effects, but it always turns out that either they are not measuring what they think they are measuring or they see a trivial filter effect which looks frightening in the time domain for those who don't understand filters.
Why can't people accept that wires are simple? Now circuits: that is where the fun is! Transducers: even more fun for those of an electromechanical bent!

How much of this thermoelectric voltage will be AC in the audio spectrum? Perhaps nanovolts?rayma said:

How come this is not a problem in the real world of electronics, wot a load of..... it isn't going to be a problem, lets look at real problems. On very sensitive analogue PCBs I have never known of any issues due to these effects on a PCB.
As it is an effect due to different metals how can cold welding help, you still have different metals as the connectors are often plated with a different metal, in the case of wire wrap often gold, so you have a copper/gold interface.

Yes, circuits are definitely more fun than the lower level physics stuff. We always do have to simplify our models to make them tractable,
and that's a good thing. Otherwise, we'd never get anywhere. But, sometimes we can use the lower level knowledge to make worthwhile progress.

Er getting signals down wires, PCB traces etc is a well defined art, and at the higher frequencies we have to look at the low level physics stuff, and the how to best get signals down wires has been studied for a long long time, RE. Heaviside and the telegraphers equation etc.
Adding more things that are not really relevant to audio signal transmission does not help the situation, such as your recent post...with no empirical data to back up the premise that it is a problem.
You forgot the micro-diodes. 😀
On a more serious note, there's a large body of anecdotal evidence that suggests demagnetizing CDs and LPs results in a significant improvement in sound quality. I wonder if the same isn't true of cables. After all it seems to me there's more likely to be magnetizable impurities in a metal wire than in a plastic CD or LP. Even if there isn't, we still need to worry about the residual magnetic fields in the plastic insulation.
Maybe this is the real reason cable break-in works so well. [citation needed] The AC current flowing through the cable during break-in causes a gentle alternating magnetic field which has a degaussing effect.
Went to the electronics supply store around the corner, picked a handful of balanced connectors out the bin , said to the guy at the counter, "I need some shielded cable for these, short runs," and he went to a roll and said, "how many feet do you want?"
I was out for under fifty bucks. It was the connectors that cost. All works fine. The critical factor I found is making solid connections.

But zero hard listening test evidence, and zero support from known materials science?godfrey said:
'Demagnetizing' CDs is so clearly nonsense that it is hard to take seriously anyone who believes in it. Even if there was an effect on raw data error rates (but there isn't) it could not affect final processed data error rates because these are essentially zero for any well-pressed CD on any non-faulty CD player.
Yeah, well, when cable demagnetisers hit the stores at $500 a pop, remember you read it here first.
Come to think of it, this is probably why everybody bitches about the sound of resistors and capacitors with steel leads - nobody bothers to demagnetise them first.

That's because speakers only deal with actual physical sound, rather than the more important imaginary sort.
You lack imagination about the gullibility of audiophiles and the willingness of the high end industry to rip them off. Try $2175.

10 Years of trial and error we discovered best sounding cable and no need for expensive stuff as BNW are equivalent or better than most expensive brands I've tried..
Neutral is what they are! As you requested.. Decent Diy Cables will cost this much and I would bet not at all close to same level of neutrality
3 foot Interconnect is 60PF
No shield and I've never found the need and I live in a high noise area..
Playing with braiding configurations I hear no audible difference.. The quality of the wire is all that is important, IME
I can send a pair for free to original Poster if He wishes? Hear it for yourself! PM if interested..
