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, and how exactly does that information help your argument?"

Sometimes I copy and paste things directly from the text books so I can avoid any arguments like I did in this case. If someone wants to argue it’s not with me.

I find physics to be pretty simple stuff, well documented and easy to demo. I see HEA many times trying to reinvent the wheel, but that just leads to heated discussions and I’d rather be listening to music.


>>>>>Well, you started the thread. Define vibration. Define audio signal. Otherwise you’re the troll. And you’re the one who asked to keep trolling to a minimum, remember? Don’t be alarmed by the word argument. It’s not supposed to be a threatening word. Well, not usually, anyway. 

If you find physics to be pretty simple stuff then you are one of the very few. I think it was Feynman who said, if you think you understand electricity you probably don’t.

And yes this is RoomTune’s 30th Anniversary (can you believe it). I did tuning long before that but 1989 was when RoomTune hit the scene.

Oh wow 30th anniversary thats cool I didn't know that!!. Ever since I have been tuning with your PZC's and using the tunable room that you designed it has brought a new perspective to me towards this hobby and what the variable tuning design can do, it's powerful. Tuning a system base on vibrations or others may say in other ways makes a lot of sense to me.

Am still burning in your Rev 6 Signature speaker hopefully it will be ready for a review soon :).

Damage Control! Damage Control! 😬

By the way, yes, I can believe it’s been 30 years as I was one of the first customers of Corner Tunes, Echo Tunes and those super cool looking brass cones.

Hi tjbhuler

Good to see you having fun! Also good to see you on Agon.

Hope it’s ok for me to share your TuneLand thread.

I think for a lot of listeners it helps following someone who has gone from the typical HEA system to a Tunable setup and seeing the path. As people are emailing me wanting to know more your presence on this forum will be helpful for those on the tuning journey themselves.

I look forward to having some exchanges with you here! It would be great if the Tunees made this a hangout.
