# Sidechain Gate Stereo

Detailed: LSP Sidechain Gate Stereo (SCG1S)

Formats: CLAP, JACK, LADSPA, LV2, VST2

Categories: Gate

Developer: Vladimir Sadovnikov

Description:

This plugin performs gating of stereo input signal. Flexible sidechain-control configuration and additional sidechain inputs are provided. Additional Hysteresis curve is available to provide accurate control of the fading of the signal. Also additional dry/wet control allows to mix processed and unprocessed signal together.

Additionally, Stereo split mode allows to apply processing to the left and right channels independently while keeping the same settings for the left and right channels.

Controls:

- Bypass - bypass switch, when turned on (led indicator is shining), the plugin bypasses signal.
- Pause - pauses any updates of the gate graph.
- Clear - clears all graphs.
- Stereo Split - enables independent compression of left and right channels.
- Gain L, R - enables drawing of gain amplification line and corresponding amplification meter.
- SC L, R - enables drawing of sidechain input graph and corresponding level meter.
- Env L, R - enables drawing of gate's envelope graph and corresponding level meter.
- In L, R - enables drawing of gate's input signal graph and corresponding level meter.
- Out L, R - enables drawing of gate's output signal graph and corresponding level meter.

'Sidechain' section:

- Preamp - pre-amplification of the sidechain signal.
- Reactivity - reactivity of the sidechain signal.
- Lookahead - look-ahead time of the sidechain relative to the input signal.
- Setup - Sidechain configuration, available values:

- Internal - sidechain input is connected to gate's input.
- External - sidechain signal is taken from additional (external) sidechain inputs of plugin.
- Peak - peak mode.
- RMS - Root Mean Square (SMA) of the input signal.
- LPF - input signal processed by recursive 1-pole Low-Pass Filter (LPF).
- SMA - input signal processed by Simple Moving Average (SMA) filter.
- Middle - middle part of signal is used for sidechain processing.
- Side - side part of signal is used for sidechain processing.
- Left - only left channel is used for sidechain processing.
- Right - only right channel is used for sidechain processing.
- Min - the absolute minimum value is taken from stereo input.
- Max - the absolute maximum value is taken from stereo input.
- Left/Right - left and right channels are being processed using respectively the left and right sidechain channels in stereo split mode.
- Right/Left - left and right channels are being processed using respectively the right and left sidechain channels in stereo split mode.
- Mid/Side - left and right channels are being processed using respectively the middle and side parts of sidechain signal in stereo split mode.
- Side/Mid - left and right channels are being processed using respectively the side and middle parts of sidechain signal in stereo split mode.

- Listen - allows to listen the processed sidechain signal.
- LPF - allows to set up slope and cut-off frequency for the low-pass filter applied to sidechain signal.
- HPF - allows to set up slope and cut-off frequency for the high-pass filter applied to sidechain signal.

'Gate' section:

- Reduction - the amount of gain applied to the input signal when the gate is closed (if negative) or open (if positive).
- Makeup - additional amplification gain after processing stage.
- Attack - attack time of the gate.
- Release - release time of the gate.
- Curve - Basic gate curve characteristics:

- Thresh - threshold, the level of input signal at which the gate becomes open.
- Zone - the size of the transition zone below the threshold.

- Hysteresis L, R - enables additional hysteresis curve:

- Thresh - threshold (relative to basic curve), the level of input signal at which the gate starts to close.
- Zone - the size of the transition zone below the hysteresis threshold.

- Mix Dry - the amount of dry (unprocessed) signal.
- Mix Wet - the amount of wet (processed) signal.

'Signal' section:

- Input - overall input gain.
- Output - overall output gain.
