Router Enhancement

[Ralf11]

how does vibration affect a digital signal?  and if it does, what level is needed to do so?

 

* that is the fly in the ointment

Jitter .

 "Google is your friend"

 

apparently it is not yours

 

Besides confusing a mechanical vibration with analog electronics, you have conflated both with a digital signal.

 

Now without a glib know-nothing reply can you explain how jitter is introduced in a router???

[Ralf11]

brings back some bad memories of grad. school...

 

but it is not a switch (!!)

if you believe what he said, you don't understand the physical universe

that's a funny one - we are moving towards neural networks tho, aren't we?

[Ralf11]

There is a bigger issue here than might appear on the surface, and it goes far beyond HiFi or audio.

 

Note what happened, step by step:

1. someone was aware of a FAQ or maybe we could call it a White Paper on singing capacitors.  That's good.  The phenomenon exists where a passive device can produce an audible sound, a vibration.

2. This got altered in his mind to the reverse effect: where a vibration can alter an electronic signal - an analog signal.  This is small, may be negligible but does exist and would cause a type of noise.  This effect too is well-known.

3. The fatal error was to take the above effect and apply it to a digital device (router) which deals solely with digital signals.

 

Now, perhaps if the noise level became large enough, it could possibly flip some bits.  This seems implausible to me, but EEE's may know better.  Even if it did, it seem implausible that the checksum would not 'catch it.'

 

The perp was unable to answer questions about any mechanism, and resorted to personal attacks instead.  An acolyte then joined him in attacking others.

 

So, that is the etiology of this disease.

 

This sort of thing goes far beyond HiFi, and is a key attack made on climate change science (by the same PR firm that was hired to fuzz up the impacts of tobacco smoke on lung cancer and other health effects). This is why I think it is important to counter these sorts of things when they arise, tho I may be biased by having to attempt to de-program both undergraduate and graduate students in a past life.

Sandyk... every piece of content above has to do with after data arrives across the network to a PC or renderer and is stripped out of its frame and packet header for internal processing into a digital audio signal. None of it applies to data in transit inside a packet/frame transport envelope. I do follow and generally endorse the content above for the issues of getting audio data cleanly output, whether it be from HDD locally or from network after frame/packet envelope removal. But these articles are not germane to network data transmission.

 

 

 

 

well put

 

(tho I doubt if it will do any good)

[Ralf11]

my personal experience is that none of my routers has been affected by vibration control

 

nor would I expect them to be so affected because my part of the universe obeys physical laws

[Ralf11]

also refer back to the checksum post (Davide256 IRRC)

 

then our own Cry Mommy poster has again confused analog (CD player) with purely digital...

 

but hey just because it defies physical law doesn't mean it can't happen - that's why I rub Caig proGold all over my router's case

Yeah right, take a magnifying glass and have a close look at the 1’s and 0’s floating through your digital equipment hahaha

 

 

- most people use a different type of scope, not that you'd know that

This is what he linked to... unfortunately, none of them are relevant to a router.

 

Lots of bad vibes to control - speaker cabinet resonances, ball bearings under a DAC or a CD player (which includes a DAC of course), emotional outbursts here and elsewhere, etc.

 

Anyone can put their router on the list too - just do a valid test to avoid the ol' snake oil swim

Ok Thank you very much Sir. I just love the thought that if I or anyone else has any doubts or questions we can always come to you and your fellow trolls to get the answers we need. Again, Thank you sooo much.

 

ones and zero’s right?

 

seriously this place would be way less entertaining wo them thick headed trolls

 

rather than attack people as trolls you would be well advised to ask politely for engineers to educate you - maybe you can better yourself that way

In the OP's specific case, ie, network streaming audio file (ie, yet to be decoded & played) tracks from a NAS on the same network & from TIDAL's online servers, there is no digital audio signal path through the network - so the router cannot be a component in the signal path!

 

the router is a component in the confirmation bias path!

 

Now please stop using science and engineering to crap on this thread and let it become yet another safe space for the snowflakes to ignore reality and snort their fairy dust

[Ralf11]

maybe less than two doesn't understand the previous discussion or comments (besides not understanding law)
