I'm not too familiar with Sound Forge but I strongly believe you can just duplicate the figure 8 channel after you recorded it and flip the phase of the duplicated track, hard panning the 2 tracks accordingly. For MS it's recommended to use the same kind of microphone but it will work fine anyways.
The setup you mentioned is correct, you are picking up the side waves with the figure 8 and the front with the cardioid. You can use this technique with anything (including guitar amps) and it gives you a great stereo image.
Let me know if it helped.

It will be a pain in soundforge since you will need three mono tracks. Get [[url=http://[/URL]="http://audacity.sou…"]Audacity[/]="http://audacity.sou…"]Audacity[/].

thanks guys.
I'll let you know how it turns out. 8-)

I've done MS recordings as 3 mono tracks many times and didn't consider it a pain at all. It was not in Soundforge, but in any case, there's usually more than one way to skin MS decoding in any program you use.

The thing you want to do before you do the recording is figure out how to use your software to decode to MS while you are monitoring so you can check your mic setup and make sure you're satisfied with the sound before you commit.

When you said that, you made it sound as though I had said MS recording is a pain to do in general. Do you see my point?

you only have to record two signals...its not an issue in ANYTHING.

Decoding, however....will be a bit of an interesting proposition in an editing tool.

In Sound Forge:
a) Take the side channel and paste it (ctrl+v) it into a new stereo file (ctrl+n).

b) Process > Invert/Flip the phase on one of the channels

c) Then mix (ctrl+m) the mid into the side... Adjust the volume accordingly.

You could probably write a script for this.

There must be plug-ins that decode M/S stereo to L/R. Soundforge 8 can load VSTs, so you could knock something up in Synthedit in minutes.. :wink:
