Noise Gate

The Noise Gate fuses three detectors instead of trusting one: a fast peak follower, a smoothed RMS average and a transient-flux sensor that spots onsets before they peak. Three Styles re-weight the blend - Classic balances all three for general program, Vocal leans on RMS so speech rides smoothly through the gate, Drum leans on peak and flux so hits crack through the instant they land. A five-state machine (closed, opening, open, hold, releasing) with separate open and close thresholds - the Hysteresis gap - ends the chatter single-threshold gates produce, Hold keeps short gaps from clipping word endings or cymbal tails, and up to 10 ms of Lookahead opens the gate before the transient arrives.

Range sets how deep the gate shuts, from gentle bleed reduction to a hard mute, and the Mode switch re-purposes the whole detector: Expander eases the floor down along a Ratio slope instead of slamming shut, Ducker inverts the law so the track dips whenever the key gets loud. Key HPF and LPF focus detection on the band that matters, the key can come from an external sidechain, and Auto Floor tracks the noise bed with a rolling-minimum estimator so the effective threshold rides just above hiss that drifts over time. The editor plots the real fused key level against the engine’s own effective thresholds, with draggable threshold and range handles, a live gain-reduction meter, a history strip and a gate-state readout.

Why it hits different

The GhostWare take.

  • Three fused detectors with per-style weighting - opens on the hit, not after it.
  • True hysteresis plus hold: two thresholds and a five-state machine end gate chatter.
  • Auto Floor learns a drifting noise bed and keeps the threshold riding above it.

Control Showcase

Every control, explained.

16 controls, named exactly as they appear in the plugin.

Threshold -80 to 0 dB (default -36 dB)

Level the key signal must reach to open the gate.

Hysteresis 0 to 24 dB (default 6 dB)

Gap between the open and close thresholds - the key must fall this far below Threshold before the gate starts closing, which kills chatter.

Attack 0.02 to 250 ms (default 3 ms)

How fast the gate opens once the key crosses the threshold.

Hold 0 to 2000 ms (default 40 ms)

How long the gate stays fully open after the key drops, before the release begins.

Release 1 to 5000 ms (default 120 ms)

How fast the gate closes once the hold time runs out.

Range 0 to 96 dB (default 0 dB)

How deep the gate shuts - 0 dB passes everything, high values hard-mute the floor.

Ratio 1 to 20 (default 4)

Expander slope: how many dB of attenuation for each dB the key falls below the close threshold.

Mode

Gate mutes below the threshold, Expander eases the floor down along the Ratio slope, Ducker inverts the law and dips the track while the key is loud.

Style

Detector blend: Classic balances peak and RMS, Vocal leans on RMS for smooth speech, Drum leans on peak and transient flux for fast hits.

ClassicVocalDrum
Key HPF 20 to 2000 Hz (default 20 Hz)

High-pass on the detector only - stops rumble and footsteps from opening the gate. The audio itself is untouched.

Key LPF 500 to 20000 Hz (default 20000 Hz)

Low-pass on the detector only - stops hiss and cymbal bleed from opening the gate.

Key Input

What the detector listens to: the module input, or an external sidechain key.

InternalExternal
Auto Floor 0 to 100 % (default 0 %)

Auto Floor: a rolling-minimum tracker learns the noise bed and lifts the effective threshold just above it as the hiss drifts.

Lookahead 0 to 10 ms (default 0 ms)

Delays the audio slightly so the gate can open before the transient arrives. Adds latency while nonzero.

Stereo Link 0 to 100 % (default 100 %)

How much both channels share one gate decision. 100% keeps the stereo image stable.

Mix 0 to 100 % (default 100 %)

Balance between the gated and dry signal.
