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.

The Attack Suppression function settings are made using the Threshold Level fader and Suppression Curve

Setting buttons.

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.

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.

2.3. Switching the Graphic Display

The graphic display section can display either the original or processed signal.
