Hi all,
someone interested in my experiences about MS Matrix on OS9?
I tried to setup the first time a MS Matrix in order to master a stereo track independently as mid and side information.
Because I would like to let all of you be a part of my learning process or maybe someone can give me an explanation about the following:
Okay, I have tried the MS Matrix setup with some hints of a youtube video (-> link below). But I was afraid all the time that the sound in MS could be different than to original source stereo file.
Therefore I run the following test: I setup the MS-matrix and tried to "erase" my created MS-Matrix with a (out-of-phase) original source. Then I could be sure that I have reproduced the stereo file exactly in mid-sid-matrix and have no loss in quality.
After some hours testing I have achieved the cancelation – but with some tricks:
The usual way is to instantiate an waves S1 MS Matrix plugin in the stereo source. The strange thing was that I have only achieved a complete cancelation when I dropped the "sides"-information by -2.5dB. The "mid"-information was 0dB, but the sides needed to be -2.5dB less. Can someone explain this to me? It seems to me that the Mid-Information (when instantiating the Waves MS Matrix) is +2.5dB higher than the sides!!!!
But why?
In order to get the cancelation done (if you want to test it in Pro Tools) is to drop the source-out-of-phase-stereo-file also -2.5dB. Then flip the phase (and check the delays because of the used plugins) and then you get total cancelation. But why this -2.5dB drop in the sides (or in other words +2.5dB more on the mid information)?
Maybe someone else find this helpful too and maybe some genius can tell me why?
Best, paule.
