LoudLAB 3

LoudLAB App

Loudness Control Solution

Mac OS X 10.11 Ready

LoudLAB is a powerful Audio File Editor, Converter and Loudness Control Solution for professionals and students alike.

LoudLAB makes loudness monitoring & control of real-time audio and files a pleasant experience. Also, the editing capabilities and built-in audio processors provide all the necessary tools to produce great masters at an extraordinary price.


LoudLAB includes a real-time metering suite that can be used on signals, with a channel setup that goes from mono to 5.1, and is completely independent from the file editor.

With it, engineers can measure real-time loudness levels to comply with EBU R-128 and ITU-R BS.1770-3 industry standards. It also includes a Spectrograph and a Goniometer.

To help with loudness compliance on different territories, LoudLAB also provides a variety of metering scales and targets.


• Momentary Loudness

• Short-term Loudness

• Integrated (a.k.a Programme) Loudness

• Loudness Range (LRA)

• True-Peak (a.k.a inter-sample peak)

• Goniometer

• Spectrograph


The LoudLAB editor also provides all of the above real-time meters, plus PPM, RMS and maximum dBFS peak meters. Plus non real-time metering utilities such as a maximum True-Peak finder, a peak history graph (Amplitude Distribution) and a loudness history graph (Loudness Distribution), which is beautifully integrated with the Loudness Leveler to display the before and after compression levels.


The editor provides operations like: Delete, Erase, Trim, Cut, Copy, Paste, Reverse, Insert Silence, Phase Invert, MS Encode / Decode and more.

LoudLAB also has a pencil tool to edit the waveform with sample precision.


All audio tools were carefully crafted for LoudLAB to guarantee a discrete and yet unique sound experience.


• Multiband (3) Linear-Phase Compressor / Expander

• 8 Band Parametric Equalizer

• Loudness Leveler + Offline Loudness Distribution meters

• Limiter / Maximizer

• MS and Stereo Mixer

• PPM and RMS meters

• Loudness, LRA and True-Peak meters

• Goniometer and Spectrograph



The DeNoiser is an essential tool in the audio restoration process.

By capturing the unique characteristics of the noise to remove, LoudLAB reduces noise precisely and seamlessly.

Linear-Phase EQ Match

The EQ Match with Linear-Phase response, allows you to equalize a signal based on the spectrum or frequency response of another.

Plus, the one of a kind Smoothing function was developed to be both precise and musical to accommodate different applications.

8 Band Parametric Equalizer

The 8 Band Parametric Equalizer is designed to fulfill the majority of equalization needs.

It operates with five curve types (Bell, High-Pass, Low-Pass, High-Shelf and Low-Shelf), a Q factor that goes up to 100 and an easy to use Musical Note to Frequency finder.

Compressor / Expander / Gate

This Dynamic Processor allows you to compress (upwards and downwards), expand or gate the signal with analogue or digital amplitude detectors and a soft or hard knee.

The unique ability to flip the transfer function, both vertically and horizontally, delivers a total freedom of control.


The LoudLAB DeEsser, offers a very discrete way of reducing voice sibilance.

Because of it's Linear-Phase Split-band characteristics, you won't even notice that the DeEsser is being used.

Pitch Shifter (DIRAC Technology)

Dirac, by DSP Dimension, is a critically acclaimed pitch shifting technology that works with both musically monophonic and polyphonic signals with equal ease and success.

Fast Loudness/Peak Analysis and Normalization + DeClipper

This is a very fast tool for peak and loudness analysis and normalisation.

With a single click you can analyse the loudness and peaks or normalize them to any target and for a variety of standards.

Furthermore, you can recover the dynamic range with our unique DeClipper technology.
