FLUX Pure Expander Plug-In

In addition to the common controls on a dynamics processor (ratio, attack, release), Pure Expander offers control over the fundamental characteristics of the dynamics processing, all in order to provide full control over the processing even in the most demanding situations.

• Extended envelope settings with Manual, Auto, and Advanced release modes
• Zero attack time for the dynamics processing by introducing a delay reflecting the attack time into the signal path
• Eight different detection modes interacting with the time and envelope settings and the integration times for the RMS detection, including specific Feed Backward modes inspired by vintage hardware for a beefy sound
• Dynamic Factor: amplifies or diminishes the extracted real-time dynamic information
• Dynamic Velocity: controls the speed of variation on the extracted dynamics information

Two parameters are provided that are unique to dynamics processing: Dynamics Ratio and Level Independent Detection (LID), which uses the dynamic range content of the signal and not just the signal levels as standard processors do.

• Dynamics Ratio controls the amount of auto ratio determined by the signal dynamics and the manual ratio setting. This literally opens up the sound, increases dynamic impression, and keeps some crests by adjusting the ratio of dynamic processing of each section in real time
• Level Independent Detection controls the amount of auto threshold determined by the signal dynamics and the manual threshold value, providing processing of the audio signal strictly in regards to dynamic range
• A Maximum mode can be engaged on the LID control, allowing for processing that accounts for the maximum values of both the standard and LID detection systems

To control the actual stereo width of the mix, a built-in M/S encoder/decoder is used to split the stereo signal in its mid and side components. The MS Width control sets the stereo width of the processed signal. A -6 dB value deceases the stereo width, while a +6 dB value increases the wideness of the stereo mix but can produce phasing issues.

The MS Mode control enables one M/S encoding matrix at the input and one separate M/S decoding matrix at the output of the dynamic processing in order to control the stereo width of the mix. When engaged, the side-chain is fed by an M/S encoded signal that is reflected in the display section. Mid channel corresponds to the normal left channel and the Side channel corresponds to the normal right channel.

Up to sixteen channels of simultaneous processing for multichannel surround configuration is provided. The processing can be disengaged on any of the channels leaving the material unprocessed, bypassing the original sound.

When operating on a multichannel bus, all channels are processed by default, though the processing can be disengaged for any number of channels, leaving the material unprocessed and bypassing the original sound. By doing this in combination with serial instances, the material on any number of channels can be processed with individual settings.

The built in preset manager and the preset morphing slider provide instant and intuitive control of all parameters and controls. In a second, everything is copied from one of the two preset slots to the other, even during playback.

The two Preset/Parameter slots, A and B, can be loaded with two full set of parameters at the same time, and the morphing slider will allow you to mix them and record the morph into your host automation.
