Topic: M/S Decode in Post?

[sickrick43]

Wanna try some M/S recording with the 744, but don't want to configure for M/S since I won't be able to accurately monitor the blend during the recording.

Got just about every audio proggie for the PC (soundforge, wavelab, samplitude, audacity)- which one has M/S mixing functions?  I
supposed I could run it analog through the V3, but I don't want to introduce an analog generation (obviously).

wavelab has a plugin called "toolsone" under the VST plugins.  that will handle your m/s matrixing.  i think you want to invert your side channel (which should be the right channel).  you'll have to set up a batch process to render the new file after you get the settings how you want them.

good luck!  PM me if you have any more questions.

Assuming you didn't have a matrix plugin, couldn't you make a copy of the figure 8 track, invert the phase on one of them and then pan the tracks hard left and right? Then you'd have two tracks (L&R of the side mic) and the one mid track? Probably harder to control this way, but I think it would work in a pinch?

yeah, this would work.  you have to pan the non-inverted one to the left and the inverted one to the right (assuming you had the negative side of the capsule facing right).  then to finish it off, you take the mid channel and mix it on top of both of these single channel recordins using the same ratio for both and you get one M+L and one M+R (which is actually M-(-R) )

I use Waves S1 Imager plugin with Wave Lab.

Also, I believe the 744 (& 722) have a built in m/s monitor function with the headphone output.  You can record discrete M & S channels, but it will do a 50/50 m/s>stereo mix to the headphone output so you can get an idea of what you're recording.  You'll have to dig into the manual for more details, but I think SonicSound did this when recording m/s at AllGood a few months back.

Voxengo offers a free VST Mid-Side plugin.

I think SF can do it natively. I forget how, but search the help file -- pretty sure it's built in somewhere...

Right you are.  Pan/Expand off the process menu.  Also have the Waves S1 Imager plugin that will work in sampllitude (which I use to bring in the whole 96/24 tracks, process and dither down to 16 bit), but that seems less "intuitive" than the soundforge one.  Guess I'll have to go out and record a "throwaway" to play with before going out and trying it on a "keeper".

On the TLM-170, I'm assuming the front of the mic (in figure goes to the left side, and rear to the right?  I've done blum a number of times from onstage, but in the room, too much close crowd on the rear lobes - especially in venue's where the floor goes up and 5 rows back may end up higher than 6/7' mic height - so you've got folks chatting directly into your rear pattern.

I know Ratdogs sound guy runs M/S from FOH (which I would think unusual, due to how far back he is).

I was just thinking of giving it a try, just to see if there's a major difference between M/S & Blum in the final output...

Thanks for the input guys...

yeah, the front of the lobe will face left.  this will make the M/S decoders work like they were planned.  if you mess it up, its not hard to fix, but the plugins are all designed for the left side to be positive and the right side to be negative.

+t and good luck!

Soundforge does it.  It is really easy.

another question for Neumann ak 20 users.  Which side does the "figure 8 - 20" logo face while recording?  Left or right?

the 20 faces the left.  that is the front of the cap.  if you look at my avitar, the 20 is on the closed side of the mount.

any mac users in the house..? have any of you folks used the matrix+ plugin..? i am stuck usinig an ibook for the forseeable future, so i will need to be using audacity to do this...

weird thing is, it seems like the plugin makes the left channel louder than the right. it isnt a big deal to boost the right channel a few db's, but this shouldnt be necessary. shouldnt both channels be of equal amplitude..? or was i just enough off center that it shows up dramatically in the end...?

it looks to me like on my akg c422, the front lobe of the fig 8 faces right.  i am assuming that the side with the leds is the front...

[BWolf]

i'm pretty sure that the front of the lobe is always going to face left.

m/s formulas are M+L and M-R, so if they were reversed, the summing formulas will be all messed up.

can't you turn the fig 8 180 degrees on that thing?
