E-NoiseGate600 (Windows-G)

An advanced JSFX noise gate plugin for REAPER that offers:

* Lookahead Control (0 ms to 20 ms): Controls the lookahead time of the gate in milliseconds. Lookahead delays the main track's audio slightly to let the gate analyze the audio ahead of time and open before the transients arrive. This ensures that the first milliseconds of transients are preserved and not chopped off. This is great for preserving the attack of percussive sounds. The latency it introduces is reported to the DAW for automatic delay compensation. Turn lookahead off by setting the control to 0 ms.

* Two Detection Source Modes:

1. Main Input: The gate uses the main track's audio for both detection and gain reduction processing.

2. Sidechain Input: The gate listens to external sidechain input for detection while applying gain reduction to the main track's audio.

* Detection Gain (-30 dB to +30 dB): Boosts or attenuates the level of the detection signal only (it does not affect the main track's level). This is useful for ensuring the detection signal is at the optimal level to trigger the gate accurately.

* Detection HPF (10 Hz to 20 kHz): A 12dB/oct high-pass filter that removes low frequencies from the detection signal. This is useful for preventing unwanted low-frequencies from falsely triggering the gate. The filter becomes active only when the frequency is set above 10 Hz.

* Detection LPF (20 Hz to 21 kHz): A 12dB/oct low-pass filter that removes high frequencies from the detection signal. This is useful for preventing unwanted high-frequencies from falsely triggering the gate. The filter becomes active only when the frequency is set below 21 kHz

* Two Level Detection Modes:

1. Peak: Makes the gate respond to instantaneous peak levels in the detection audio. The loudest peak levels are held for 30 milliseconds to minimize "gate chatter" (rapid opening and closing). This mode is ideal for audio requiring fast gate response like drums or percussion.

2. RMS: Uses Root Mean Square calculation to make the gate react to the average power of the detection audio over a time window. This makes the gate less responsive to instantaneous peak levels. This mode is ideal for audio requiring slower, smoother gate response like pads, piano or other sustained sounds.

* RMS Window (1 ms to 1000 ms): Only active in RMS mode. It defines the time window for RMS averaging and determines how averaged the RMS level is. Shorter windows (1 ms to 140 ms) make the gate react quickly to changes in peak level, longer windows (400 ms to 1000 ms) make the gate react very slowly to changes in peak level, while medium windows (150 ms to 390 ms) offer a middle ground between fast and slow gate response.

* Three Detection Channel Modes:

1. Stereo: Makes gate dynamically react to the loudest of the left and right channels. Ideal for stereo detection signals where the content may shift between the left and right channels.

2. Left Only: Makes the gate react only to the signal levels from the left channel. This is useful when the detection signal is panned to the left.

3. Right Only: Makes the gate react only to the signal levels from the right channel. This is useful when the detection signal is panned to the right.

* Threshold (–80 dB to 0 dB): Displayed as a white line on the detection level meter. This is the main threshold the detection signal must exceed for the gate to open. When the signal drops below this threshold, the gate closes (unless the Hold or Hysteresis is set above 0).

* Hysteresis (0 dB to 30 dB): Creates a second, lower closing threshold displayed as a yellow line on the detection level meter. The gate opens when the detection signal exceeds the main threshold, but only closes when the signal drops below this close threshold. This prevents rapid opening and closing of the gate that occurs when the detection signal hovers around the main threshold.

* Range (-80 dB to 0 dB): Controls the maximum amount of gain reduction applied when the gate closes. At 0 dB, there is no gain reduction (the gate is disabled). A setting of -20 dB provides gentle gain reduction and preserves ambience, −50 dB is nearly silent, and −80 dB provides complete silence.

* Attack (1 ms to 1000 ms): Controls how fast the gate opens from a closed state when the detected signal exceeds the threshold. It's the gate's opening time in milliseconds and uses an exponential curve for a smooth opening. Fast attack (1 ms to 10 ms) preserves transients, mid-range attack (15 ms to 40 ms) softens transients, while slower attack (50 ms to 1000 ms) creates a pronounced fade-in effect as the gate opens.

* Hold (0 ms to 1000 ms): Controls how long the gate remains fully open after the detected signal drops below the close threshold. Once the signal level falls below the close threshold, hold keeps the gate fully open for a set time in milliseconds, preventing the gate from closing during brief dips in the signal level. Hold is inactive when set to 0 ms.

* Release (1 ms to 1500 ms): Controls how fast the gate closes after the detected signal drops below the close threshold and the hold time has expired. It is the gate's closing time in milliseconds and uses an exponential curve for a smooth closing. Fast release (1 ms to 40 ms) makes the gate to close quickly, which is ideal for drums, percussion, and for creating choppy rhythmic gating. Slow release (150 ms to 1500 ms) makes the gate close gradually, which is ideal for sustained sounds requiring smooth gate closure. Medium release (50 ms to 140 ms) provides a middle ground between fast and gradual gate closure.

* Dry/Wet (0% to 100%): Controls the mix between the original (dry) signal and the gated (wet) signal, ranging from 0% (fully dry) to 100% (fully gated). This is useful for subtle and experimental gating effects.

* Output Gain (–30dB to +30dB): Sets the final output level of the gated signal only. This control does not affect the detection signal level.

* Filter Priview ON/OFF (Button): When turned ON, it solos the output of the detection high-pass and low-pass filters, allowing user to hear the exact signal being used to trigger the gate. This is useful when tweaking the filters to isolate the desired trigger frequency. It is available for automation as “Filter Preview” in the plugin's parameter list.

* Invert/Duck ON/OFF (Button): When turned ON, it inverts the gate's behavior. Instead of the gate opening when the detected signal exceeds the main threshold and closing when the signal drops below the close threshold, it opens when the signal drops below the close threshold and closes when the signal exceeds the main threshold. This is typically used for ducking when combined with Sidechain Input mode, making the plugin function like a sidechain compressor. For example, inserting the plugin on a music track and routing a vocal track as a sidechain to the plugin (with detection source set to Sidechain Input and Invert/Duck turned ON) will make the music automatically duck whenever the vocal track plays. It is available for automation as "Invert/Duck" in the plugin's parameter list.

* GUI Detection Level Meter: Displays the current detection signal levels on a -80 dB to 0 dB scale. The white line represents the threshold, and the yellow line (when Hysteresis is set above 0 dB) represents the close threshold.

* GUI Gain Reduction Meter: Displays the current amount of gain reduction being applied by the gate. The meter reflects normal gain reduction by default, but shows inverted/ducked gain reduction when the Invert/Duck button is ON.

* GUI Detection Level Readout (dB): A numerical display of the maximum detection signal level since playback started. The value automatically resets on each playback start.

* GUI Gain Reduction Readout (dB): A numerical display of the current amount of gain reduction being applied by the gate.

* GUI HPF/LPF Status Indicators: Show the active/inactive status of the detection high-pass and low-pass filters.

* Zipper-Noise-Free Operation: Advanced interpolation ensures no zipper noise during slider automation or real-time adjustments.

* Minimal CPU Usage
