Vibratory or Not?

This is a discussion that for me began on the Stereophile forum which went horribly wrong in my opinion. I was wondering though if this same topic could be discussed here as it comes up a lot in one form or another. My background has been about vibratory tuning as far back as the 70's work in the recording industry and continued into home audio and beyond. The audio signal is one that can be easily tuned, I doubt there is much room there for debate, but we will see, it's Audiogon after all. This being the case I have always concluded that the audio signal is vibratory so has anyone I have ever worked with. It's a common and sometimes even daily practice for someone here to make a vibratory adjustment changing the sound which is obvious to all.

On some of these forum threads however you will see posts saying to get rid of the vibration, without any explanation as to how to remove vibration without altering the audio signal. Every vibratory move I have ever seen done changes the performance of the sound. I've also been a part of the variables of the audio signal during play in real time. If the audio signal is not vibratory how does it change?

I invite you to discuss the vibratory structure and nature of the audio signal.

thanks, lets keep trolling to a minimum please

OK, Class, settle down. Put your listening ears on. This is how the big boys do it.

Sneak preview:
“To operate effectively, the lengths of LIGO's arm cavities (i.e. the distance between the test masses at the ends of each arm) must not vary by more than a fraction of a picometer (one-trillionth of a meter). To hold the masses in place, we need to push on them–but very carefully, and we use the reaction chain (see figure above) for that. Simple motors made of permanent magnets and electrical coils push on the upper masses; these 'voice coils' work like audio loudspeakers, with the coil producing a magnetic field which attracts or repels the magnets. On the test masses themselves, we use more gentle electrostatic forces, like that which attracts a balloon rubbed on a sweater to a wall (or hair to a comb on a dry day). The goal is to keep our hands off the masses as much as possible so they will move only due to gravitational waves.”

michaelgreenaudio OP
With electricity being such an important part of our systems lets define.

"Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. In early days, electricity was considered as being not related to magnetism. Later on, many experimental results and the development of Maxwell’s equations indicated that both electricity and magnetism are from a single phenomenon: electromagnetism."

Electromagnetism is one of the Four Fundamental Interactions.

For a quick review

"Fundamental interactions, also known as fundamental forces, are the interactions in physical systems that do not appear to be reducible to more basic interactions. There are four conventionally accepted fundamental interactions—gravitational, electromagnetic, strong nuclear, and weak nuclear. Each one is understood as the dynamics of a field."

>>>>>>What is that supposed to be? I suspect you were searching cyberspace for a connection between electricity and vibration. Better keep looking.

I know it may seem like a stretch, and it practically is, but when talking about vibrations and sound and regardless if you prefer them extra/modified/unadulterated, vibrations inside your head are very important part of the equation. However, they practically never get mentioned. It may be much harder to control them than placing a tube under the CD player, but maybe someone really dedicated can take them into consideration when tuning/tweaking sounds. Stick a helmet on the head (what material?), use Afrin before listening session, or something more innovative. That would be a really thorough approach to addressing vibrations. Hairstyles are another very important component of vibration management, yet they are also rarely mentioned.

As far as influence of vibrations on electrical signal in the head go, it may be much less pertinent than in other electrical applications.

You know, brain vibrates too and sometimes not quite in a right way. 
This is one of the most senseless threads on Audiogon of all times.
There is only one fundamental force in music.
It's the emotions, stupid.
