A. BeforeUsingThisManual
a.1. Basic Terminology
This manual assumes that you are familiar with basic operational principles and terms used in Macintosh/Windows
systems, such as Menus, Windows, Scrollbar use, Cursor, Markers, Files, Data, and Commands. Below is a list of
terms used in this manual:
Drag
Hold down the mouse button and drag the mouse to move les or data.
Click
Place the cursor, then quickly press and release the mouse button. Used for selecting objects on screen.
Double Click
Place the cursor, then quickly press and release the mouse button twice. Used for executing onscreen tools.
Shortcut Keys
Combinations of key strokes used to execute a command.
On a Macintosh, "shift", "control", "option(alt)", "command(apple)", as well as Function "F" keys are used.
On Windows, "shift", "control", "alt(option)", as well as Function "F" keys are used.
For example, to save the current le, you can either use the mouse to select Save in the File menu, or just press
on a Mac, and on Windows.
Default/Default Value
Initial settings or conditions for parameters.
Dialog
For operations that require the user to make a choice, a window containing buttons and check boxes (Dialog) will
open. An example of a use of this term in this manual: "a Dialog box will be displayed." Alert
This is a window that contains warnings about the current operation. An example of a use of this term In this
manual: "An Alert will be displayed/An Alert box will appear" when an operation cannot be undo-ed.
Clip Board
This is where data that has been cut or copied is temporarily stored. This is a standard feature on both Macintosh/
Windows.

B. General
NML RevCon-RR is a Pro Tools Audio Suite plug-in that was developed to enable the removal of reverberation from
a sound source.
NML RevCon-RR's feature set includes not only reverb reduction, but also two types of augmentative parameters
tailored to dialog sound. The rst is an envelope correction feature called Attack/Release Suppression, which
improves the clarity of dialog recordings by suppressing reverberation that could not be removed completely. The
other is a Noise Separation feature that increases the effectiveness of the Reverb Reduction, together with a Remix
feature that adds noise back to the processed audio for more natural sounding results. This Noise Separation &
Remix feature can help balance dialog and background levels, and add natural sounding clarity to the dialog in a
way that, until now, could only be achieved by placing the mic closer to the source.
b.1. Features
- The world's rst removal process that uses reverberation prediction- Simple operation with a single Reduction knob
- Spectrogram, audio envelope display (before/after process)
- Correction parameters tailored to dialog sound (Attack Suppression, Release Suppression)
- Noise Separator & Remix processing

1. Preparation
Because the NML RevCon-RR is an Audio Suite plug-in, basic operation consists of making a selection containing the
source audio, then generating a reverb reduction processed le.
Here we assume that there is already a Pro Tools session open.
1.1. Opening the Plug-in
1. In the Pro Tools Edit window, select a range of audio or region(s) that you would like to process.
The maximum selection length for processing is 15 minutes.
2. Select "NML RevCon-RR" from the AudioSuite menu.
3. The NML RevCon-RR will open. The currently selected waveform will be displayed on the plug-in graphic
display.

2. NMLRevCon-RROperation
2.1. Using Reverb Reduction
To use Reverb Reduction - NML RevCon-RR's primary function - adjust the "Reduction" and "Release" knobs.
1 "Reduction" determines how much reverb is reduced (removed). Parameter values are 0~100%.
The default setting is 0%, which has no effect.
100% is the maximum amount of reduction.

2 "Release" determines the length of reverberation that is to be targeted for processing.
The value range is 30~500msec, set in 5msec increments.

2.2. Using Reduction and Level Adjustment on Dialog
Attack Suppression and Release Suppression are augmentative functions designed for dialog sound, that suppress
the reverb elements that could not be removed using the Reverb Reduction function. Attack Suppression suppresses
the prominent sonic energy following loud passages, while Release Suppression suppresses the sonic energy
following a drop in level. This results in increased clarity of the dialog sound.

2.3. Separating Noise
Noise Separation and Noise Remix are augmentative functions that enhance the effectiveness of the Reverb
Reduction process. The reverb reduction process works better when there is less noise, thus the inclusion of the
Noise Separation function which can separate noise from the dialog. This noise separation process enables the
removal of reverb that is associated only with the dialog sound.
The Noise Remix function adds the separated noise back to the reverb-reduced (processed) sound. This function
helps preserve ambience, which is an important element of a natural sounding background, while allowing dialog to
stand out. The Remix level, which adds the noise elements back to the signal, can be adjusted to taste, allowing you
to balance the noise level with the processed dialog.
1 Set the Sample Period which is used as the basis for Noise Separation.
Click on the to enable Noise Sample Period setup mode. While in this mode, you can adjust the noise
sample period in the graphic display by dragging.
If you place the mouse cursor on the edge of the noise sample period, the cursor will turn into a allowing you to
drag the edge.
Initially, the noise sample period is automatically set to the rst section in the selection that is under -20dB below
Median Level.

2 If you would like to nely adjust the noise sample period, click on to zoom in on just the noise period in
the graphic display.
Clicking on will loop audition only the noise sample period, so that you can listen to the noise elements.
3 Enabling Noise Separation processing
Clicking on will execute the Noise Separation process.
Use the ReMix Noise fader to set the amount of noise that you would like to add back to the processed signal.

If you would like to completely remove noise from the signal, we recommend using a dedicated noise
reduction plug-in before using the NML RevCon-RR.
