As glupson, the first to respond said, "Sound is, in the simplest term, a vibration. No vibration, no sound." I totally agree - no debate necessary! Yes we have the sound waves in the room and the audio signal itself is an oscillating/vibrating signal. So the question is - do we want to use these vibrations which we agree exist, to our advantage, or to damp them out, thereby affecting the musical signal that created them. To me, the answer is obvious - we want to use them to enhance our musical experience. However, knowing how to do that is something very few people understand and even fewer people actually experience it to its fullest extent. Those who don't experience it will always question and debate it. I agree totally that isolating vibrations affects the sound, some think creating a better "sound", others like me, think is just creates a "different" sound. But stepping back and learning how to truly use all those vibrations to enhance the sound is what will drive this hobby to the "fun" place it should be! Michael Green is the only person who has shown me how to do this, and has demonstrated it to me in its fullest extent. Kudos to Michael for starting this thread! Everyone is entitled to their opinion, and I'm sure plenty of folks will come up here with opinions contrary to mine, and that's fine, that's what this forum is for. Just let me leave you with this final thought - experience one of Michael's fully tuned systems that uses all the vibrations to enhance the music, before you throw rocks at the idea. I'm sure Michael would be happy to have everyone stop by, just not all at the same time! Cheers!
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

MG - I concur. I have never heard two isolated systems sound the same - only different from an non isolated system. Regarding Geoff's continuing problem with the word vibratory in this context, I offer the Merriam-Webster definition:1
: consisting of, capable of, or causing vibration or oscillation
2
: characterized by vibrationWe all know that the pressure waves in the room coming from the speakers are a result of the amplifications of the audio signal, which oscillates over a range of frequencies and changes in amplitude. The pressure waves produce vibrations. Therefore, we are dealing with a variety of vibrations/oscillations/vibratory signals and waves. Choose the wording you prefer - it's just different ways of saying the same thing. |
