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

Glubson was obviously talking about acoustic waves in the room. Glubson has this knack for stating the obvious.

Well Glupson did a good job in this case, because he was correct. Remove vibratory from audio and there is no sound. The electricity to the system wouldn't work, the parts that host the signal wouldn't work, the drivers on your speakers wouldn't work nor would the hairs in your ears work.

There would be no pressure in your room for you to hear and we wouldn't be here talking about it cause there would be no Earth, the Earth vibrates :)

Geoff you're trying to remove too big of a part of nature to make your point. Hey an "Audio Point" :)

Folks in audio saying "kill vibrations" makes no sense because that's what audio is. If you kill vibratory interaction the whole planet goes down the drain.

but of course that could be me vs 20,000 somethings or whatever that trolling was LOL

I would think so, it doesn't get easier than this Geoff. But, you believe that audio is not vibratory, is this correct? You believe the hairs in your ears don't move, nor does the cone of a speaker? If they aren't moving what are they doing to interact?

If you're concerned over a word, then go ahead and give it a shot. If vibration is being used by these billions of people incorrectly than there must be a singular better word.

Your speaker cones are_______your ear hairs are___________electricity is___________sound is the act of ___________ . You don't like the word vibrating so what word do you want, maybe "moving" maybe "forcing" maybe "interacting". Tell us what one word would you like to use in the place of vibrating and the world can entertain this. I'm not trying to be a smart "A" Geoff, just trying to use what the rest of the world uses when describing sound with a nice easy to understand set of word roots.

This is becoming quite an excellent example of the Brer Rabbit and Tar Baby routine. But I can’t figure out if you’re the Tar Baby or Mr. Fox. 🦊

Just to be clear, I never said audio is not vibratory and I never said audio is not vibration. You are putting words in my mouth. This was bound to happen when you don’t define your terms. As Dylan says, words have different meaning to different people. If I say the word house we all have a different picture of what a house is. If isolation was not real as you seem to believe then LIGO would never have been able to detect and observe gravity waves. Just like the optics in LIGO the optical system must be isolated and protected from vibration that would interfere with the observation of gravity waves the optical system in CD players must be protected from vibration, especially the very low frequency seismic type vibration, otherwise the CD player will not sound as good as it could. The same logic applies to turntables since very low frequencies excite the circa 10 Hz Fn of the tonearm and cartridge.
