In the Thread: 2+3 surround sound??
Post Subject: I would like to make my own judgmentPosted by Romy the Cat on: 7/14/2021
Well, since Mr. Bongiorno is not around, and his units are
not available to experiment then it is what it is. I have no doubts that this
version of semi-binaural possessing works well. What I do not know if it compromises
what we get from 2 channels. This is why I call it “2+3 surround sound” as the
main playback is still 2ch stereo and center channel and back channels are juts
complimentary that do” something” but they do not make the main channels worse.
I do not have a clear vision how to feed the center channel and back channels. I
would not trust the Mr. Bongiorno’s device as well. You see if I try it have a
negative result then I would not know if it was a conceptual problem, or the
problem was with this specific mixing device and the Bongiorno’s implementation.
So, I would like to make my own judgment. Years back there
was a devise Yamaha DSP-E800 that was center channel and back-channels extractor
and that have delay options. I do not know how they did it, most likely digital
but if it was all that the DSP does then I can deal with it. The phase manipulation
is perfectly fine on DSP level, the key is that DSP should not attenuate or
filter. I do not know how good AD/DA in there and I do not think that it will
be the last solution. Still, I feel it much be “enough” for back channels, at least
to experiment.
Also, I would like to look into the requirement for center channel.
I do not think that I will be able to find a good one ready to go with the demotions
I have in my mind. To build is complicated. I know exactly what tweeter to use
in there to decompress sound, but I have no knowledge of a good 4” MF driver. I
also do not know how full-range my center channel should be. I think I will
take a pair of good JBL monitors, form from it a center channel and will see
what it takes me.
I did some listening today using Bose Solo as center channel.
I certainly had an interesting stereo effects but as soon I begin to “hear” Bose
the sound went sound very rapidly. For
sure that Bose Solo with it’s phase vandalizing is not proper devise to experiment,
but I wanted to test it right the way…Rerurn to Romy the Cat's Site
