Moth balls work pretty well. When I lived in Desoto I would throw moth balls over the fence into the wooded creek area so the snakes wouldn't come into the yard. One day I did that and noticed an entire family of Possums scramble when they smelled it. Racoons are real bad in attics. They may work on...

Okay, now I think I understand it. It's pretty cool. I would like to hear it. Thanks for that BTW! I'm pretty sure the guy a Nuemann that thought it up was a major MS geek. Takes one to know one I guess. :oops: :geek: I was proposing doing the the normal EE response in the same style as the VAB. Ma...

Since you only have the encode side would you do the same kind of thing where you subtract the side channel HPF from the main signal by summing it with the main signal reverse polarity? You mean only the encode side available when the decoder is used for the "VAB84" configuration? There m...

In the case where the low frequency uncorrelated information is small there is no reason to switch it in. The lathe automation can take care of it. You need to use it when there is a lot. True. What I also found is that the LF is highly uncorrelated it should be mono'd regardless of whether it's go...

Paul when I ran tests on this using program material I didn't experience level build-up from the additive process. I think that's because the level of side relative to mid is usually quite small. The EE will have no effect on mono sources that are mono by virtue of being panned center. When they bec...

I was thinking it might help you make that sausage faster without having to patch in that EQ and compressor to fix what the EE took away. It would basically have a single knob like an EE: Out, 75, 150, 300 etc. For in phase it would act like an EE. For out of phase more like the original LF was mono...

The dynamic nature of the filter makes it more audible than a simple EE IMO. Conceptually it seems better, like it would only do what is necessary and get out of the way when it's not necessary. In practice having the filter cutoff move around mostly serves to make it more audible. That is of cours...

Thanks Paul for checking in. I'll pore over those docs. What I think you may have missed in this thread as it eventually evolved is that the technique I'm showing here doesn't actually use MS. It just uses the MS board. In fact Mid isn't used at all. The first experiment I ran was to HPF Side in MS....

The schematic below shows how the decode section of the Precision MS Matrix board can be used to emulate the Neumann VAB84 with a fixed frequency filter and optional increased slope. The VAB84 and this implementation are both different from the EE70 and E77 which eliminate low frequency difference ...

I found a second way to do this externally as an insert to the MS matrix. The circuit I'm testing right now is second order with a high cutoff. There is virtually no separation below 200 Hz; at 1 kHz its about -25 dB. On a lot of material - already mastered - I can't hear it working which I suppose ...
