Categories: Expander

Developer: Vladimir Sadovnikov

Description: 

This plugin performs increasing of dynamic range of mono input signal. Flexible sidechain-control configuration and additional sidechain input are provided. Both downward and upward modes are available. Also additional dry/wet control allows to mix processed and unprocessed signal together.

Controls:

• Bypass - bypass switch, when turned on (led indicator is shining), the plugin bypasses signal.
• Pause - pauses any updates of the expander graph.
• Clear - clears all graphs.
• Gain - enables drawing of gain amplification line and corresponding amplification meter.
• SC - enables drawing of sidechain input graph and corresponding level meter.
• Env - enables drawing of expander's envelope graph and corresponding level meter.
• In - enables drawing of expander's input signal graph and corresponding level meter.
• Out - enables drawing of expander's output signal graph and corresponding level meter.
• Link - the name of the shared memory link to pass sidechain signal.

'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 expander's input.
• External - sidechain signal is taken from additional (external) sidechain inputs of plugin.
• Link - sidechain input is passed by shared memory link.
• 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.
• 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.

'Expander' section:

• Mode - expander mode: Up (upward) or Down (downward).
• Ratio - expander ratio.
• Knee - size of the knee.
• Makeup - additional amplification gain after processing stage.
• Attack Level - threshold of the expander, placed in the middle of the knee.
• Attack Time - attack time of the expander.
• Release Level - relative to the Attack Level threshold that sets up the threshold of Release Time.
• Release Time - release time of the expander.
• Hold - the time period the envelope holds it's maximum value before starting the release.
• Mix Dry - the amount of dry (unprocessed) signal.
• Mix Wet - the amount of wet (processed) signal.
• Mix Dry/Wet - the knob that controls this balance between mixed dry and wet signal (see Mix Dry and Mix Wet) and the dry (unprocessed) signal.

'Signal' section:

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