LoudLAB ToolBox

The navigation bar on the left-hand side presents us with the means to navigate between tools. Starting with the "Inserts" section (EQ & Dynamics), followed by a "Loudness Leveller" and the "Master Bus" tool.

Tools can be switched on and off (when available), by the toggle boxes next to the tool name.

Furthermore, the "Filter Designer" and "Dynamics" tools can be dynamically flipped (order of processing) by pressing the arrow next to the section name.



Filter Designer

LoudLAB Filter Designer

The "Filter Designer" tool offers 8 fully controllable filters.

All bands can be either: "high-pass", "low-pass", "high-shelf", "low-shelf" or "bell" filters.

Each band is assigned to a color represented on the graph, and the black line represents the sum of all curves.

Parameters:

Frequency (20 to 20000 Hz), Q factor (0.3 to 100) and Gain (-24 to 24 dB).



Dynamics

LoudLAB Dynamics

The "Dynamics" tool is a Multiband(3) Linear-Phase compressor/expander.

The three bands can be individually bypassed and switched between compressor and expander mode.

Parameters:

Threshold (0 to -70 dBFS), Ratio (1.1:1 to 50:1), Attack (0.01 to 1000 ms), Release (1 to 10000 ms) and Makeup Gain (-40 to 40 dB).



Loudness

LoudLAB Loudness Leveller

Loudness Distribution Graphs and Leveller.



The Loudness Distribution is a phenomenal way of analysing the results of compression, and therefore LoudLAB displays it for both the input and output signals.

The output distribution is extrapolated from the leveller parameters in real-time. Therefore, in order to get the output distribution, we need to plot the input one first. The later can be plotted at any time by pressing the plot button.

We can always use the Distribution Graphs for the purpose of analysing the file loudness range, even if the Leveller is not in use.



The Loudness Leveller is based on psychoacoustic principles and therefore ideal to control Loudness Levels. The attack / release times are calculated automatically by LoudLAB, yet, the user can select the Time Base (Momentary and Short-term loudness) that best fits the type of signal that is being levelled.

Parameters:

Time Base (Momentary and Short-term Loudness), Threshold (0 to -70 dBFS), Ratio (1.3:1 to 4.0:1) and Makeup Gain (-40 to 40 dB).



Master Bus

LoudLAB Master Bus

Finally we have the actual master bus, which is composed of the "Master Out" section, the limiter and Peak+RMS meters.

The "Master Out" section is divided into Mid/Side and Left/Right faders, plus individual Phase Shift, Mute and Solo functions for a full control of the output signal.



The Limiter is the last tool on the chain, and uses an automatic attack/release system exclusively designed for LoudLAB, which also makes it very straightforward to use.

Parameters:

Ceiling (0 to -30 dBFS) and (pre ceiling) Gain (0 to 30 dB).



The Peak+RMS meters (green -> peak || blue -> RMS) on the right-hand side, display amplitude information for both the Mid/Side and Left/Right signals.

The red dots represent the maximum amplitude found since the last "reset", which can be performed at any time by pressing the reset button.
