REAPER 7.0: What’s New
Gain Reduction Metering
The mixer Master Track main controls have the same functions as the Master Track which 
can be shown via the Track Master in track view. 
Gain reduction metering is now available as an option.

Left click on the Output button (shown above right) to toggle 
between Stereo (gray) and Mono (orange) modes.

Right click on the Output button to set any one of four available 
Mono modes – Left + Right, Left only, Right only, Left - Right.

Left click on the FX button to display the master FX Chain.

Right click on the FX button for the Add FX context menu.

If the Master FX chain is displayed you can use any of the FX 
management keyboard shortcuts that you can use on your tracks.

Right click on the VU area to display controls to manage the VU 
meters display settings (right). Meter options for the master when 
displayed in the TCP are Peak or Loudness: for the mixer, these 
are Peak + Loudness (as shown here), Loudness Only or Peak 
only. Options for loudness meter display are:
RMS (Root Mean Squared) stereo/max or  RMS/Max only
Loudness Units relative to Full Scale momentary (LUFS-M)/max
LUFS-M/LUFS-I (integrated)
LUFS-S (short term) /current
LUFS-S/ max (loudness range)
LUFS-S/LRA

Optionally, you can choose for gain reduction to be displayed on 
the meter (as a vertical bar descending from the top, as shown 
below right). This can only be shown when you are using a third party or native 
plug-in (such as ReaLimit) that calculates gain reduction and reports it to the host.

Readout can be set to LUFS-I or Maximum.

LUFS, RMS and Peak issues are explained in Chapter 6 of the User guide.

There is an option to display multichannel peak metering.

Settings, where appropriate, available for managing the window include RMS 
window, Display offset, Display gain and Red threshold. 

This includes the option to display output in multichannel mode (e.g. when working 
with surround sound). Disabling this option will ensure a two channel display.
Loudness meter settings include:
Meter display: Stereo RMS, Combined RMS, LUFS-M, or LUFS-S.
RMS Window: the length of time (in milliseconds) that should be used for RMS 
calculation.
Display offset: this offsets the coloring of the RMS metering while keeping the position 
constant. 
Display gain: this applies gain to the RMS meter value: for example, if you set display 
gain to, say, 6dB, a sine wave will show the RMS value a t a higher meter reading than 
the peak value.
Red threshold: this determines the level at which the meter will turn red.
In the example shown above, if you were targeting -14dB LUFS or RMS, then with display offset at 14dB the 
display would go green at -14dB, and with red threshold 4.0dB, it would go red at -10dB.
Note: There is an option in Appearance, Track Meter settings to scale gain reduction from plugins by a level 
that you can specify.
Track Gain Reduction Metering: 
Track gain reduction monitoring for plug-ins that measure gain reduction and report it to the host can be 
enabled in Preferences, Project, Track/Send Defaults. Display the Track meter display dropdown and 
enable Display gain reduction for plug-ins that support it.
Track meter defaults will be applied to new tracks only, not to existing tracks on existing projects.
