Fuji Immersive Limiter

The Red Rock Sound Fuji plug-in is an advanced level maximizer and lookahead peak limiter
that enables mastering engineers to enhance sound file resolution and boost production
master levels in both stereo and immersive mixes.

Even though the Fuji Limiter can handle multi-channel buses, its controls are as easy to use
as traditional one- or two-channel limiters.

Groups
This module allows you to select an Limiter from four available. The Limiters can be arranged in parallel or in series, this allows you to process channels with different Limiter settings. To select a sequential or parallel arrangement of group effects, click on the gear button in the lower right corner of the plugin, parameter: Effect Group connection.

For example: the first Limiter is only the mid channel, the second Limiter is only the side channel, the third Limiter is the left and right channel. For multi-channel modes: the first Limiter is only the left and right channels, the second Limiter is the center channel, the third Limiter is the LFE, etc.

You can rename Channel Group Buttons for ease of use. To rename the selected Channel Group button, right- click on the button.
In order to turn on the solo (listen) of the Limiter, double-click on the selected Channel Group number.

The Channel Group solo mode glows yellow, to exit solo mode, double-click again. For two-channel modes, only one unit can be solo mode. For multi-channel modes, one or more units can be soloed.

To bypass selected Limiter processing, press the selected Channel Group number one click + shift. In bypass mode, the button will glow red.

You can also copy all Limiter settings to another Channel Group. To do this, select the Channel Group from which you want to copy the settings, then click on the copy button, then select the Channel Group to which you want to copy the settings.

Input Routing
Input Routing lets you choose between 44 common channel setups, starting from Stereo up to 7.1.4 and 9.1.6. Simply select in the input routing module the channel setup that fits your track.

You can also create your own input routing profiles. 16 independent channels are available.

Click on the edit button next to the input routing selection display. Hold down the shift button and select the desired number of channels. Name selected channels in order. Then click save and name the profile.

Channels
In this module, you can select (activate) the channels that the Limiter will process in selected Channel Group.

Threshold Fader
Sets the input level around which limiting starts acting to a significant degree
The available range from -30 to 0 dBFS;

Release Fader
Sets the time it will take for the attenuation to return to 0 dB when the energy falls below the
threshold.
The available range from 0,01 to 1000 ms;

Auto Release
When this button is enabled, the Release control acts as an overall scaling factor around
which Auto Release calculates the ideal time for the signal to return to zero.
When Auto Release is off, the release time is set directly by the Release control.

Global Input Gain

Main Input Gain controls the overall input level of the plug-in input, before all Channel Groups.

Macro Control
In the studio, when working with hardware devices, they often turn knobs with both hands; on a computer with one mouse, this is difficult to do, so we tried to implement something similar using the Combo knob.

For convenience and speed up work, you can bind several parameters to one macro
controller.

For example: Link the Threshold parameter from all 4 «Channel Groups" (The Channel Groups selection is located in the upper right corner of the plugin. More about Channel Groups selection on page 3) to one macro controller and control them all at the same time. Or bind two different parameters to one controller, invert one of them and boost the input gain and lower the output ceiling using only one macro controller. There are many possible uses,
just try this.


To bind parameters to a macro controller, click on the Macro button.
Note: To rename a Macro button, right-click on the button and enter a
new name.

When the Macro button is active, additional parameters appear for those controllers that can be controlled.

Select the parameter you want to control, it has 4 controllers, they correspond to the «Channel Groups" numbers (The Channel Groups is located in the upper right corner of the plugin. More about Channel Groups on page 3), select the one you need. Adjust the parameter control sensitivity, right is positive value (blue color), left is inverted (red color), To return the knob to position 0, click twice. To return the knob to position 0, double-click with the left mouse button.

Global Output Gain
Main Output Gain Main Output Gain controls the overall output level of the plug-in output, after all Channel Groups.

Undo/Redo
Undo and Redo functions allow undo and redo of changes made to the plug-in parameters.

A/B
A/B buttons allows you to load two independent settings and compare them quickly.

Preset Display
Factory presets are included in the plug-in installation, installed in the following locations:
Mac: Users\[user name]\Music\Red Rock Sound\RRS Fuji\Patches
Windows: C:\Users\[user name]\Documents\Red Rock Sound\RRS Fuji
You can save the current Comp settings as the Default preset. - Full Reset – is the default
preset

Load
Load button allows loading of presets not stored in the locations described above.

Save
Save button allows for save of user presets.

Oversampling
OS x_ activates 2x, 4x or 8x oversampling, 1x disables oversampling. (note that when the HQ mode is on, CPU will be loaded more than usual).

Global Preferences
button opens Global Preferences menu.

GUI Rendering
This switch allows you to choose between GUI rendering engine:

Normally, no need in switching rendering mode manually, plug-in try to initialize D3D9 then OGL (if D3D9 failed) and CPU (if OGL failed) automatically. But if you have problems with the GUI, you can manually switch and test different rendering methods at work.

This switch is available only in the Windows version of the plugin. For the Mac version, this is not necessary.

Note: Drivers of some video cards (for example, Intel Arc A380) in D3D mode adversely affect the plug-in (periodic noise or whistle), if you encounter a similar phenomenon, use OGL or CPU.

SIMD optimization
This switch enables or disables SIMD optimization, it can be used by multichannel processing with high oversampling. It is undesirable to use in mono and stereo modes, SIMD only slows down the plug-in due to the overhead of splitting the data for optimization.
(Currently in beta testing)

SIMD MacOS
- In the ARM version, you can enable or disable NEON;
- In the Intel version, you can enable or disable SSE2.

SIMD Windows
- In the Intel version, you can enable or disable AVX (if supported), or SSE2.

The Windows version has a limitation: if the CPU does not support FMA, then the optimization will not work, even if AVX or SSE2 is supported.

Note: Enabling/disabling SIMD is saved in the project for each plugin individually. i.e. if a specific instance of the plugin slows down, then you can enable SIMD for it, and others, if they are in the project, will not be affected by this optimization.

Effect Groups Connection
This parameter switches the arrangement of effect groups to serial or parallel.

Note: If the processing effect introduces latency, then it is better to choose a parallel connection for this plugin, because when using a serial connection, the latency will increase many times.

System requirements

All Red Rock Sound products require a computer with appropriate DAW host software (none of which are included).

Plug-in Activation requires Internet connection!
You can go offline as soon as plug-in is successfully activated.

Versions from 1.0.0 and newer of the Red Rock Sound plug-ins have the following minimum requirements:
Mac OS X 10.14.6 or higher for AU.
Mac OS X 10.14.6 or higher for VST.
Mac OS X 10.14.6 or higher for AAX. Latest version of iLok license manager.
Windows 7 or higher (Windows XP not tested).

Mac: Intel Core i3 / i5 / i7 / Xeon / Full Apple silicon support (M1 or higher).
Windows: Intel Core i3 / i5 / i7 / Xeon / AMD Quad-Core or newer.

In theory, any AAX, VST, VST3, AUv3 compatible host application should work. However, due to plug-in host differences between DAWs - and our own rigorous testing standards - we only officially test our plug-ins and instruments in the most recent versions of Pro Tools, Logic Pro, Cubase, Ableton Live, Studio One, Reaper, and Bitwig. Red Rock Sound plugins are not tested in non-listed systems, but they most likely work as long as the system requirements are met. We cannot guarantee a solution for issues in unsupported systems.
