Thanks for your quick reply
That "general rule" exactly was my initial guess before I did the experiments.
What I'm doing (or trying to) is not to use Har-Bal as a dynamics processor, rather in this "unusual application" I am using Har-Bal to analyze general dynamic properties of the program material.
In addition to my explanation above, let me clarify:
I am loading the same track as both source and reference.
When I then match (overlay) the green curve of the source to the yellow curve of the reference (the first approach above), what I get is equal to subtracting the difference curve of the two from the green curve: Gs + (Yf - Gs). Switching to the frequency response view after doing this, will show the difference curve (Yf - Gs).
In the second approach I did it the other way around, matching the Yellow curve of the source to the green of the reference: Ys + (Gf - Ys). Switching to the frequency response view after doing this, will show the difference curve (Gs - Yf), and this time the freq. curve is inverted in comparison to the freq. curve of the first approach.
The audible results are really not interesting, but confirms the application. In the first approach everything sounds flat or lifeless, in the second it sounds boomy or overcompressed. This makes sense since one approach reduces the dynamic differences and the other increases them.
But, it is not really the resulting EQ that I'm after, its the frequency response (as a source of information), because this tells me how the material were compressed in the different frequency areas. Information which could be useful for configuring multiband compressors, or learning how compression was done with given material (at least that was the idea..).
See the idea?
