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

Michael, let me draw your attention to my posts earlier today in response to the same and related questions.

Geoff in regards to isolation you don't believe in the audio signal being vibratory I take it? How do you describe the variable interaction the signal has with the fields, or as some would say field?

In our stage testing we have been able to establish such control as to virtually be able to shape the soundstage by using the audio signal's variables without distortions. With isolation as you term it how are you able to make compensations to the sound. I have never heard any two "isolated" systems to produce the same sound. If a system is isolated you would have the same sound would you not with any other "isolated" system, which has never happened to the best of my knowledge.

interesting conversation

Yes I have read your posts thanks. This is why I'm careful to ask with more specificity.

I answered your second question regarding whether I believe the audio signal is vibratory several different times. As I also stated earlier you must define your terms before any discussion can occur. Terms such as vibration, oscillation, audio signal. Otherwise, what’s the point?

As for your question regarding air bladders/tubes/springs and load I answered that specific question earlier today around sevenish.

Geoff when you were instructing with "oscillating or vibrating" memos saying that the audio signal is not either but sighting an alternating current. You do realize that AC is measured in oscillations don't you? In fact in electrical engineering you are taught that AC is vibratory current.

BTW audionuttoo "Certified Professional Engineer and Class A Master Electrician" is pretty high up on the food chain of engineers.

Sometimes I get a little kick out of you and kosst, as you both try to marginalize our teaching here at the tune without knowing our collective schooling. It's kind of a joke amongst us when we talk about "audiophile experts". We usually find that the audio internet EE's who boast the most actually have the fewest courses under their belts in reality, or the most dated.
