An introduction to FLUX:: Pure Limiter, based on information from the maker and distributors: what it does, how to use it and who it may suit. It is not scored.
Clean transparent limiting with full control of the audio levels even on dramatically increased levels, without any artifacts introduced on the processed audio material.

What is Pure Limiter?
Pure Limiter is a limiter in FLUX::'s Pure series. The official description presents it as clean, transparent limiting that preserves the character of the material even when the average level is raised a lot, intended for the very end of a processing chain.
Beyond the usual Input, Output, Threshold and Knee controls, it exposes the fundamental characteristics of the release behaviour. Three operating modes are offered: Manual (classic controls), Automatic (minimal interaction) and Advanced (all parameters).
Release has Max/Min limits, with dynamic high-pass and low-pass filters on the signal feeding the release, a Dynamic Factor that scales the extracted dynamics information, and a Dynamic Velocity that sets how quickly it changes. These help when fine tuning is needed.
With up to 16 input/output channels, it can be used on multichannel material as well as stereo. The display shows the waveform and the limiting action so you can see what the processing is doing.
Three operating modes
Manual is classic, Automatic needs minimal interaction, Advanced exposes everything. You could use Automatic when you want a quick setup and Advanced when refining.
Detailed release control
Release Max/Min, high/low-pass filters feeding the release, Dynamic Factor and Dynamic Velocity are adjustable. It might help when the limiter reacts too much to low frequencies.
Lookahead (0/20 ms)
The gain starts to drop before a potential peak arrives, which the maker calls a key point for avoiding distortion.
Two waveform displays
Mode A shows the output waveform with limiting in red; Mode B shows the output as a histogram, with limiting and the release value (blue line) on a separate histogram. The maker says Mode B helps in Advanced mode.
Make Up and channel link
Make Up raises the output gain from the threshold. Link Channels applies limiting on one channel to the others, which could help keep the stereo image steady.
Up to 16 channels
Input and output reach 16 channels, so it may also serve multichannel productions.
A/B slots and morphing
Two full settings are held at once and can be blended with the slider; the morph can be recorded by host automation.

How to use it
- Insert Pure Limiter at the end of the chain, for example on the master bus.
- Start in Automatic mode to get the general behaviour.
- Adjust Input (or Threshold) to decide how much limiting happens.
- Set the final ceiling with Output.
- Choose Lookahead 0 or 20 ms and check its effect.
- For more control, switch to Manual or Advanced and adjust Release max/min and the filters.
- Toggle display modes A and B to watch the limiting action.
- Use True Bypass to compare, and store variants in A and B.
Final mix stage
It might sit on the master bus to manage loudness.
Mastering
The Advanced mode could be used for careful refinement.
Post-production and streaming levels
It may help when you want to raise overall level while holding peaks.
Multichannel work
With 16-channel support it may be considered for surround projects.
Who it may suit
- People looking for a limiter aimed at transparency
- Those who want to switch between automatic and manual operation
- Users who want detailed control of release behaviour
- Producers working in surround or other multichannel formats
Good to know before you buy
- An iLok.com user account is required (the iLok USB key is not required).
- Windows is 64-bit only and needs a graphics card with OpenGL 2.0 support; USB displays are listed as unsupported in the official specifications.
- The standard FLUX:: license does not include VS3 (for Pyramix / Ovation); it is sold separately by Merging Technologies.
- Also included in the All Plugins Pack ($14.95/month) and Complete Pack ($79.95/month) subscriptions.
