Flux Elixir v3

Elixir v3 – The Premier Real True Peak Multichannel Limiter Plug-in

Elixir v3 is a novel kind of program limiter carefully designed to accomplish a truly pure natural sounding result without altering the nature of the audio material and its timbre.

Intended to fulfill the requirements of the broadcast, post-production and mastering industry, Elixir v3 provides real True Peak output level in accordance with the ITU-R BS.1770 and EBU R128 norms, and for surround/multichannel operation Elixir provides up to eight channels of simultaneous processing.

User Interface And Workflow

Elixir’s straightforward interface makes it exceptionally easy to achieve great results, even under a tight deadline. Simply set the input level, adjust the Threshold according to the amount of limiting desired, and finally enable Make Up for gain compensation and loudness addition – That’s it!

For truly delicate and fine processing tasks (mastering etc.) Elixir v3 presents a new innovative concept called Stages, providing the option to set the algorithm to perform the limiting processing in multi-stages, in order to achieve even more precise and natural sounding results.

Example: If the threshold is set to -3 dB and the ‘Stages’ parameter set to 3, the first stage will limit at -1dB, the second stage will limit at -2dB and the third will limit at -3dB, with analyzing performed in each of the three stages.


Elixir v3 is built around our latest 64-bit version 3 framework, improving the processing performance dramatically with 500 to 1000 percents improvement measured depending on the host environment.

The graphic rendering in Elixir v3 is using a GPU-efficient 2D/3D graphic engine. The engine, introduced first in the Pure Analyzer System, is based on the OpenGL standard optimizing the audio-to-visual experience utilizing the GPU on the computer’s built in graphics card.

The algorithm in Elixir v3 uses an oversampled representation of the audio sample as reference when defining the gain envelope, while the actual processing is applied only to the original none oversampled data, all in order to reduce artifacts (like aliasing) and to achieve the most precise and excellent sounding result presenting none, or effectively reduced, conventional limiting pumping effects even during heavy processing.

Open Sound Control Support

Open Sound Control (OSC) is a content format for messaging among computers, sound synthesizers, and other multimedia devices that are optimized for modern networking technology. Bringing the benefits of modern networking technology to the world of electronic musical instruments, OSC’s advantages include interoperability, accuracy, flexibility, and enhanced organization and documentation.

With the Flux:: version 3 (v3) framework support for OSC is introduced in order to allow for remote control of the plug-in parameters using OSC enabled devices and software applications such as TouchOSC for iPhone / iPod Touch / iPad.
