Double MS Tool (2011)

Surround Plug-in for RTAS, VST

Properties

  • decodes the three Double M/S signals to a 5.0 mix
  • available for free
  • requires a multi-channel software host

The two older plug-ins "Double MS Tool (2011)" and "Double MS Tool BF (2012)" do not support aax and are no longer supported. The new plug-in will be released soon.

Description

The SCHOEPS "Double M/S Tool" plug-in enables customized, intuitive decoding of the three signals of the Double M/S system.

Features and Application of the "Double MS Tool" are described here. You can download the plug-in for free.

If the plugin doesn't work or the format is wrong, an ordinary dematricing without the plugin is possible easily:

The easiest way of routing the three microphone signals Front, Fig-8 and Rear to the loudspeakers L,R,C,LS and RS works as follows:

  • Front to C
  • Duplicate the Fig-8 channel
  • M/S Matrix from Front and...

  • Front to C
  • Duplicate the Fig-8 channel
  • M/S Matrix from Front and Fig-8 for L and R
  • M/S Matrix from Rear und Fig-8 for LS and RS

System requirements and installation:

VST Windows/Mac: The VST plug-in is used in a sequencer program offering a Steinberg VST interface. The host software has to offer a multichannel VST interface such as Sequoia, Samplitude (both from v9.0), Cubase, Nuendo, Wavelab, Audio Mulch.

VST is a registered trademark of Steinberg Media Technologies GmbH

RTAS Mac: Use the RTAS installer. The installation procedures will guide you and ask for the relevant paths. Digidesign Pro Tools LE systems will need the "Complete Production Toolkit".

Read the Tutorial for the Installation of the plug-in.

The plug-in was designed and developed by SCHOEPS. The VST Windows plug-in was created with the help of the IHA at the University of Applied Sciences Oldenburg/ Ostfriesland/ Wilhelmshaven; the VST and RTAS Mac plug-in was created with the help of the Institut für Musikwissenschaft/ Musikinformatik at the HfM Hochschule für Musik Karlsruhe.

Practice

After recording the three Double M/S signals (front cardioid, figure-8, rear cardioid) to three tracks in a sequencer program, they can be decoded by the plug-in to a 5.0 mix. Decoding is intuitive because the resulting polar diagrams of the virtual “output channels” are displayed in real time.

Any change of a parameter is visible on the spot as a change of the polar diagram. The audio signal also changes in real time without interruptions, allowing settings to be optimized in a quick and comfortable way.

After recording the three Double M/S signals (front cardioid, figure-8, rear cardioid) to three tracks in a sequencer program, they can be decoded by the plug-in to a 5.0 mix. Decoding is intuitive because the resulting polar diagrams of the virtual “output channels” are displayed in real time.

Any change of a parameter is visible on the spot as a change of the polar diagram. The audio signal also changes in real time without interruptions, allowing settings to be optimized in a quick and comfortable way.

The plug-in is customized for the use of SCHOEPS microphones in a Double M/S setup. It has been tailored to the sensitivities of the CCM 4V and CCM 8 compact microphones (cardioid, figure-8) or the corresponding capsules MK 4V and MK 8. The built-in equalization is furthermore designed to match the CCM/ MK 8.

Input and output channels:

  • Input 1 (L): CCM / MK 4V front (cardioid)
  • Input 2 (R): CCM / MK 8 (figure-8, positive phase left)
  • Input 3 (C): CCM / MK 4V rear (cardioid)
  • Output 1, 2: L, R Output 3, 4: C, -
  • Output 5, 6: LS, RS

Control elements:

  • "Polar pattern" of the output channels C, L/R and LS/RS. It is continuously adjustable between 0 (= figure-8) and 1 (= omni)
  • "Microphone angle" between the resulting output microphones L/R and LS/RS. It is continuously adjustable between 0° and 90°
  • "Rear delay" of the LS/RS channels in order to avoid localization errors. It is continuously adjustable between 0 ms and 50 ms
  • "HF roll off" of the LS/RS channels to avoid localization errors - a first-order low pass of (6 dB/oct.), continuously adjustable between 1 kHz and "off"
  • "Volume" for the C, L/R, LS/RS channels - continuously adjustable between 0 dB and "off"
  • "Mute" for the C, L/R, LS/RS channels
  • "Presets": Enables quick recall of factory presets as well as saving and loading of user settings
  • Display of the polar diagrams of the output channel: Five polar diagrams in distinct colors make the resulting directivity characteristics visible. You always hear what you see.
  • Peak meter to control the function and the level of the three input and five output channels

One of the shortcomings of 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 M/S Tool the signal processing automatically avoids this artifact; all parameters may be varied independently.

This also makes the plug-in interesting for two-channel recording. Thus the diversity of coincident recording is optimally demonstrated. Use of the plug-in is intuitive, and does not require training.
