Flux Pure Expander (Digitalt produkt)

Pure Expander, capable of anything from mild expansion to hard noise-gating, is a versatile tool for cleaning up spillage from recordings, remove noise or reverb, leakage from drum sessions or microphone bleed. By reducing the gain below threshold, it gives you full control over the material making it easy to tighten up the mix and reduce any unwanted low-lever clutter.
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.
Two parameters are provided that are kind of unique to dynamics processing; Dynamics Ratio and Level Independent Detection (L.I.D), using the dynamic range content of the signal and not just the signal levels as standard processors do.

To control the actual Stereo width of the mix a built-in MS encoder/decoder is used to split the stereo-signal in its M and S components in order to control the actual stereo width of the mix.

The MS Width Control – Sets the stereo width of the processed signal. A -6 dB value deceases the stereo width. A +6 dB value increases the wideness of the stereo mix but can produce phase issue.

The MS Mode Control – Enables one MS encoding matrix at the input and one MS 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 a MS encoded signal that is reflected in the display section. M channel corresponds to the normal left channel. And the S channel corresponds to the normal right channel.

Up to eight 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 multi-channel bus all, up to eight in total, 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.
