Librae#

Mastering-grade mid/side and stereo dynamics processor

Overview#

Librae is a mid/side and stereo dynamics processor capable of compression, expansion, limiting, and many types of distortion. It is useful for both master-bus applications and creative processing: its harmonic and dynamic processing options make it a dream for contemporary sound design as well as mixing. Its controls are somewhat nontraditional but quite simple to use, as the envelope extraction is adaptive and designed to be as transparent as possible. Whether you need gentle compression to bring together a drum kit or extreme limiting to make a mix loud and impactful, Librae is an excellent addition to any session.

Adjusts the output level of the plugin.

Mid <-> Side

Changes the balance of mid vs. side. Signal flow: applied after Pre/Mid/Side and before Post.

Goniometer

Displays the level and correlation of the left and right signals.

Envelope display

Shows audio processing over time. The dark gray is input audio, and light gray is output. The orange and cyan line shows the difference in amplitude: orange is compression, and cyan is expansion. Magenta shows the gain difference from input to output.

| |

Pauses the envelope graph.

Scale

Changes the speed (time scale) of the envelope graph.

Presets#

Presets are stored in the computer’s file system, and the controls below allow for modification and navigation through the files and folders of presets. You can create a new preset “Category” by creating a subfolder in the preset directory, and saving new presets within it.

load

Load a preset.

save

Save a new preset.

< > (category)

Loads the next/previous folder of presets in the preset directory.

< > (preset)

Loads the next/previous preset.

nudge

Applies a small amount of randomization to all tonal parameters and modes. Randomization can be bypassed per control in individual parameter modulation menus. Useful for creating slight variations of sounds.

rand

Completely randomizes all tonal parameters and modes. Randomization can be bypassed per control in individual parameter modulation menus. Use this to create inspiring new sounds and ideas.

reset

Resets all parameters to their default settings.

Processor select and quick-access controls#

Librae contains four dynamics processors: Pre, Mid, Side, and Post. The four tabs in the center column contain five duplicated parameters per band for quick access, and a bypass button. Click on a processor in the center column to edit it further. Each band has the following controls:

Static curve graph:

Displays the curve applied to the signal, and the level of the signal.

Input level

VU meter(s) displaying the level of incoming audio. The green bar is RMS, the yellow line shows peak, and the red line shows maximum peak level. Reset maximum peak by clicking.

Output level

VU meter(s) displaying the level of outgoing audio. The green bar is RMS, the yellow line shows peak, and the red line shows maximum peak level. Reset maximum peak by clicking.

Blend

Dry/wet blend: at left, only the unprocessed signal is passed through, and at right, only the processed signal is passed through. Points in the middle are a blend of both signals (useful for effects like parallel processing).

Gain

Adjusts the level of the signal into the limiter. Higher settings increase average level and reduce dynamics.

Room

Increases the amount of compression applied to the signal.

Floor

Increases the amount of expansion applied to the signal; at high levels this adds a noise-gating effect.

B (bypass)

Bypasses all processing.

Out

Adjusts the output level of the processor.

Processor controls#

Each processor has its own dynamics and distortion parameters. To edit a processor’s settings, select it by clicking in the center column.

Blend (linked with Blend knob in center column):

Dry/wet blend: at left, only the unprocessed signal is passed through, and at right, only the processed signal is passed through. Points in the middle are a blend of both signals (useful for effects like parallel processing).

Gain (linked with Gain knob in center column):

Adjusts the level of the signal into the limiter. Higher settings increase average level and reduce dynamics.

Saturate

Increases saturation after Gain.

Room (linked with Room knob in center column):

Turning this up increases the amount of compression applied to the signal.

Floor (linked with Floor knob in center column):

Increases the amount of expansion applied to the signal; at high levels this adds a noise-gating effect.

Release

Adjusts the rate of the envelope extractor. Higher settings result in more aggressive processing.

Soft Drive

Increases the amount of soft clipping.

Soft Blend

Blends between the unclipped signal at left and the soft clipped signal at right.

Zero Pop:

Turning this up adds zero-crossing distortion to the signal.

Hard Drive

Increase the amount of hard clipping.

Hard Blend

Blends between the unclipped signal at left and the hard clipped signal at right.

[name] Out (linked with Out knob in center column)

Adjusts the output level of the processor.

Stereo Link:

At right, the same dynamics processing is applied to both channels. At left, the left and right channels are processed separately. Points in between are a mix. Settings toward the right can emphasize stereo imaging but can also create unwanted emphasis on either channel.

Weight High:

This controls a high-shelf EQ in the sidechain path, increasing or decreasing the dynamics processor’s sensitivity to high-end signals.

Weight Low:

This controls a low-shelf EQ in the sidechain path, increasing or decreasing the dynamics processor’s sensitivity to low-end signals.

Modulation#

All Noise Engineering plugins feature a comprehensive routing system making use of a variety of modulation types and sources. When modulation is enabled on a parameter, a box showing the range of enabled modulation will appear, and a small indicator will move within the range box showing the exact position of the modulation.

Types of modulation#

Parameters can be modulated from a variety of sources:

LFOs

Four onboard LFOs that offer a variety of modes, from simple waveforms to step sequencers. More detail on LFO modes can be found in the section below titled “Modulation page.”

Macros

Four macro sliders can be assigned to any number of parameters. The macros can in turn be mapped to MIDI controllers, automated, or modulated with other LFOs.

Env

Envelope follower. Turns the dynamics of the incoming signal into a modulation source.

MIDI CC

Parameters can be assigned to MIDI CCs. (Note: MIDI mapping of effects is not supported in all DAWs.)

Modulation Assignment#

When a parameter is right-clicked (Control+click on Mac), a context menu appears with modulation routing options:

Parameter slider

A copy of the parameter being modulated, for easy adjustment.

On

Each modulation source has a checkbox; when checked, modulation from that source is enabled.

Index

Sets the amount of modulation from a particular source. Fully left, modulation is bypassed.

Dir

Direction. Sets the polarity and inversion of incoming modulation.

• --> (unipolar): modulates from the point selected on the parameter up to the level indicated by the Index setting
• <-> (bipolar): modulates around the center point set by the parameter
• <-- (inverted unipolar): opposite modulation from unipolar
• >-< (inverted bipolar): opposite modulation from bipolar

Curve

Each modulation source has a Curve slider that changes how modulation affects the parameter. In the center, modulation is linear, and the parameter movement matches incoming modulation exactly. To the right modulation is more logarithmic, and to the left more exponential.

Allow Randomize

When checked, this parameter can be randomized when “rand” (Tone page) is clicked.

Learn CC (only visible when MIDI Learn is checked on the Config > Interface page)

Click this to enable MIDI CC learn on a parameter. Move a parameter on your MIDI controller and the plugin will exit learn mode and the parameter will now respond to that CC. If clicked by mistake, click Waiting on CC to exit learn mode. Click Forget CC to remove an assignment.

Clear modulation

Resets modulation checkboxes, amounts, direction, and curve. Does not affect CC assignments.

Modulation Page#

Click the sections in the left column to navigate to that page and edit modulator settings and routings.

LFO 1-4#

Index

Sets the modulation range of the LFO.

Type

Sets the type of LFO. Options include Wave, Step, and ADR, described in detail in the sections below.

Sync

Sets the source of timing for the modulator. * Free: A single completely freerunning LFO; never resets. * Transport: Speed is set in seconds, but the LFO follows the transport of the DAW. * Tempo: A single LFO that is synced to the DAW’s tempo and transport.

Speed/Beats

Sets the rate of the LFO. In unsynced modes, this is a slider that sets the rate in seconds. In synced modes (Tempo and Poly Tempo), this is a fraction that sets the rate in beats (for example, 4/1 would be equal to 1 bar in 4/4 meter). If a synced mode is selected, the rate can be doubled or halved with the *2 and /2 buttons respectively.

Reset LFO

Resets the LFO back to its default state, respecting Type.

Type: Wave#

Shape

Morphs between different waveforms.

saw/sin/tri/sqr/was

Selects a shape preset for the waveform. Choose saw, sine, triangle, square, or inverted saw.

Phase

Changes the starting point of the wave.

0/90/180/270

Selects a preset for the phase of the waveform.

Time Warp

Skews the timing of the waveform.

Noise

Adds randomness to the waveform.

Color (only visible when Noise is above minimum)

Changes the intensity of randomness added to the waveform.

Type: Step#

Speed/Beats

Sets the rate of the sequencer. In unsynced modes, this is a slider that sets the rate in seconds. In synced modes, this is a fraction that sets the rate in beats (for example, 4/1 would be equal to 1 bar in 4/4 meter). If a synced mode is selected, the rate can be doubled or halved with the *2 and /2 buttons respectively.

Count

Sets the steps in the sequencer; the up and down arrows change the count by one, and the *2 and /2 buttons respectively double or halve the count.

Smooth

Adjusts how smooth the transition between steps is.

Time Warp

Skews the timing of the sequencer.

Random

Adds per-step randomization to the sequence.

Graph

Edit your sequence here by clicking and dragging or use the preset buttons: * rand: Randomizes the sequence entirely. * nudge: Slightly changes the values of each step. * up: Generates an ascending pattern across the steps. * dn: Generates a descending pattern across the steps. * ud: Creates a triangle pattern across the steps. * du: Creates an inverted triangle pattern across the steps.

Macro#

Mac 1-4

Four sliders that can be assigned to any number of other parameters, and modulated by LFOs or MIDI CCs.

Env#

Envelope

Modulated parameters column#

When a modulator (LFO, Macro, or Other) is assigned to a parameter, the parameter will appear in this list when on that modulator’s page. For instance, if LFO 1 is modulating Attack, click LFO 1 on the left side to view the modulation amount, curve, and checkbox for Attack (and any other LFO 1 modulated parameters) on the right.

Group

Selects a category of parameters, grouped by location in the interface. For example, the Fold parameter is in the Oscillator group.

Param

Selects a parameter from the current Group category.

Add Route

Adds modulation routing for the selected parameter from the selected modulator.

Clr Routes

Click twice to remove all modulation assignments for the current modulator. To remove a single assignment simply uncheck the On box.

Add Rand

Adds a random modulation destination.

On

Each modulation source has a checkbox; when checked, modulation from that source is enabled. When unchecked on this page, it is removed.

Index

Sets the amount of modulation from a particular source. Fully left, modulation is bypassed.

Dir

Direction. Sets the polarity and inversion of incoming modulation: * --> (unipolar): modulates from the point selected on the parameter up to the level indicated by the Index setting * <-> (bipolar): modulates around the center point set by the parameter * <-- (inverted unipolar): opposite modulation from unipolar * >-< (inverted bipolar): opposite modulation from bipolar

About NE#

Noise Engineering is located in Los Angeles, California. We started around 2014 when Chief Noisemaker Stephen McCaul wanted a hobby for his off time from his day job and started making Eurorack modules in a spare bedroom at home. One thing led to another and a couple of years later, he and wife Kris Kaiser quit their day jobs and took the company full time. Noise Engineering has since grown in size and has established itself as a well-regarded and innovative synthesizer brand, with products in Eurorack, 5U, and multiple software platforms.
