Post Subject: The mental aimPosted by Romy the Cat on: 6/14/2023
Paul, what I am saying has nothing
to do with your Troels project but rather a psychological exercise to understand
what truly is going on. Also, I very much not knocking at your door with my
mental approach to audio objective am trying to demonstrate that everything is
not so simple.
So, you are injecting int
the room one more acoustic system that for sure “increase the density of Music”
in your room. How can we methodologically differentiate from the changes you
experience after you put your central channel in play and the changes you would
experience if you increased the radiating surface of your right and left
channel? It is not clear what kind signal you use to drive your central channel
and not clear how your right and left channels are installed in the context of
your listening room. So, from perspective of general audio analysis we still do
not know if the improvements you might have related to the functionality of the
“central channel” or related to the functionality of “another channel”. Here is
a little methodological tip that I use myself to understand what is going on. When
you make acoustic change like this, try to take your focus from what became
better towards to observing what become worse. For whatever reason when this
think about what become worse we are dealing with known N it multiple time help
me to debug problem much more accurate.
Anyhow, if I were in your
shoes I would experiment to drive the center channel from different type of
signals, probably a good digital signal processor would help you with
experiments To get out of main signal sum, delta, different phase shifts, and all
of it might be very much frequency dependent. The digital companies did a tone
of research in this direction. While you experiment with this do pay attention
not only to what became but what became worse. Interestingly, I do not
recommend to find error configuration when amount of worse is minimal and to
use it. However, knowing in which configuration the damage from central channel
is minimal will give to you a reference point upon which you can keep your
mental aim.Rerurn to Romy the Cat's Site
