BG Sidechain Dynamics
version 1.0
What is the BG Sidechain Dynamics all about ?

BG Sidechain Dynamics is a combined Compressor and Noise Gate effect
with sidechains based on auxilairy communication (channels).
It has been designed according to hardware prototypes , and special care
has been taken in the audio algorithm design to make it sound just as good
as any high quality analog hardware compressor and noise gate available
in the market !
Based on a unique emulation of a high-end analog compressor & noise gate
used in professional studios - it also have a commercial VST version !
(see bottom)

How does it work ?

The plugin have 4 Modes of operation : SIMPLE, LEVEL, COMPRESSOR
and AUDIO GATE.
SIMPLE mode contains of a single chain 2-in-1 effect box with Noise Gate
and Compressor that operates one after the other and with no sidechains.
LEVEL mode contains a single Noise Gate , and its output is redirected
to one of the 3 auxilairy bus channels selected to be used as sidechains
for the two remaining modes (COMPRESSOR and AUDIO GATE).
COMPRESSOR mode is a Sidechain Compressor that have its sidechain
coming in from one of the selected auxilairy bus channels.
AUDIO GATE mode is a Sidechain Gate that have its sidechain
coming in from one of the selected auxilairy bus channels.
Here's a little background on Noise Gates and Compressors:
A Noise Gate is a dynamic processing effect used to expand dynamics range.
Basically it is an automatic gain control device that will increase the signal
level when it passes a specific threshold level , and leaving it quiet or low if
the signal is below the threshold level.
Noise Gates are in the top importance when it comes to the mix stage.
They form the basic noise reduction and cleaning effects that makes the
mix sound more clear and much more pleasant to the ear which makes the
big difference between amateur sound to professional sound !
A Compressor is a dynamic processing effect used to reduce dynamics range.
Basically it is an automatic gain control device that will reduce the signal
level when it passes a specific threshold level , and leaving it unchanged if
the signal is below the threshold level.
Compressors are one of the most important consideration within a mix
and have the same level of approach as an EQ might have since a proper
use of a Compressor can make the small/big difference between an amateur
or unpolished production, to a finished & professional sounding mix !

How to use BG CompGate ? (Parameters Description)

Noise Gate
Threshold | : | This sets up the Noise Gate's threshold limit. Whenever the signal passes this volume level it will activate the expander and make it start working.
Ratio | : | This sets up the Noise Gate's volume increase ratio. If the signal is above or below the threshold (depends on Mode) its volume will be reduced to 1: Ratio of its volume.
Attack time | : | This sets up the Noise Gate's attack time. The attack time setting tells the Noise Gate how long it takes to fade into the expansion once the signal's threshold limit exceeded !
Release time | : | This sets up the Noise Gate's release time. The release time setting tells the Noise Gate how long it takes to fade out of the expansion once the signal got out of the threshold zone !

Mode

:

This sets up the Noise Gate's way of operation.
Usually , most noise gates operate on NORMAL mode
which means they will expand dynamic range when
signal is above the threshold , INVERSE mode
makes the Noise Gate work in the opposite direction -
it will expand the dynamic range when signal is below
the threshold level.

Compressor
Threshold | : | This sets up the Compressor's threshold limit. Whenever the signal passes this volume level it will activate the compressor and make it start working.
Ratio | : | This sets up the Compressor's volume reduce ratio. If the signal passed the threshold , its volume will be reduced to 1: Ratio of its volume.
Attack time | : | This sets up the Compressor's attack time. The attack time setting tells the Compressor how long it takes to fade into the compression once the signal's threshold limit exceeded !
Release time | : | This sets up the Compressor's release time. The release time setting tells the Compressor how long it takes to fade out of the compression once the signal got out of the threshold zone !
Output Gain | : | This sets up the Compressor's output gain increase. This is required since the Compressor reduces the dynamic range , and by that it decreases the signal's volume.

Knee

:

This sets up the Compressor's gradient of compression.
Usually , a soft knee settings causes signal to sound
more "warm" when its compressed while a hard knee
might cause signal sometimes to sound "compressed"
and change the ammount of power that was in the
original signal.

Other Parameters
Mode | : | Switches between the 4 modes of operation - SIMPLE , LEVEL , COMPRESSOR and AUDIO GATE
Channel | : | Selects which auxilairy channel will be used for the sidechains.
Sidechain | : | On modes COMPRESSOR and AUDIO GATE only - solos the sidechain signal only.
