Title: Schoeps Double M/S plugin...(new, I think?)
Post by: RebelRebel on April 04, 2007, 09:23:40 AM

I subscribe to resolution magazine, and saw mention of this plugin from schoeps, so I thought id post it here. requires two cardiods and a figure 8.

That's seriously cool.
Don't think I'll have an application for it anytime soon but it's really cool.

Free taboot!

Cool tool.

Looking at the photo of the interface, I was struck by the ability to adjust mic angle and polar pattern independantly.  This is confirmed by a statement at the bottom of the page:

One of the shortcomings of a conventional M/S recording is the mutual dependency of opening angle and polar pattern: when the opening angle is varied, the polar pattern is also changed and vice versa. In the Double MS Tool the signal processing automatically avoids this artefact: any change of a parameter is independent of the other. This also makes the PlugIn interesting for two-channel recording...

I wonder how they do that?  any insights?
This could be a very interesting tool for 'regular stereo' M/S work.

+ T Teddy nice I would love to screw around with this all I need is to borrow an mk8

The site mentions that the software makes some EQ and polar pattern corrections based on the Schoeps mics' responses. I'd guess that means a low frequency boost for the mk8 if nothing else.  No reason you couldn't try other mics, the corrections would not be as optimized, but some form of low end augmentation would be adventageous for any fig-8 with a typical low end roll-off I'd think.  Since those optimizations are made for mics that are good in polar & freq response and to begin with, I doubt they would be any worse than a 'dumb' M/S matrix for non-Scheops mics & may be better.

Doubtful, but I wonder if there is some way to adjust the EQ and pattern corrections, which could optimize the software to other mic choices as well.

Can you use this with single M/S?

Nop. The whole idea is how you mix the forward and backward pointing cards. Adds nothing if you only have one mid mic.


Theoretically (always remember that theory and practice are two different things).

1) you can describe a cardioid as having one figure 8 and one omni mic (some early ones actually were made this way).

2) if you have two of these cardiods, back-to-back and add equal amounts from them, the 8 part is removed and all you have is the omni.

3) if instead you subtract the two signals, the omni parts are removed and all you have is the figure 8 part.

So in effect, by simple means you can modify the M mic to go from omni over cardioid to figure 8 and all the patterns between. This is what underlies the independant adjustment of stereo width and pattern.

  No, but you can use it to make an MS recording out of a DMS one.

cool thanks. didn't know if there was something out there better than my Kelly Stereo Tools

This is what the plug-in looks like to give you an idea of what it is and how it works.

Gutbucket, when the magazine said that "this also makes the PlugIn interesting for two-channel recording," the "also" refers to "5.1 surround and also two-channel stereo"--but in both cases, you need three coincident microphones and three recorded channels.

In other words the plug-in can produce a two-channel output from three recorded channels, though its primary mode (and the main reason it was invented) was to produce 5.1 surround from three recorded channels.

Is that a little clearer?

Yes.  The 3rd mic is required to gain the pattern/angle independence regardless of the number of output channels.

Can anyone please walk me through the procedure of loading this decoder into Sound Forge?? 
I have the file....  I think.....  but I don't know what to do with it. 
Thanks.
