SoftGate is a universal AU plugin designed to assist in sampling and crafting sample-based instruments. Unlike traditional noise gates that abruptly cut off sound, SoftGate focuses on gentle noise reduction and de-essing by softly rolling off high frequencies as the gate engages. This approach maintains natural decays in instrument samples and reverb impulses, allowing them to fade smoothly rather than stopping suddenly.

The plugin offers intuitive controls such as Bright Threshold and Darken Speed to shape how the gating and high-frequency attenuation behave. The Base Silence parameter acts like a de-esser, defining how deeply the gate reduces noise and hiss. Instead of completely eliminating background noise, SoftGate aims to reduce it subtly, preserving a natural sound while minimizing listener fatigue and harshness.

Using SoftGate enhances sample instruments by delivering a warmer, cleaner sound with less intrusive background hiss. It also improves the decay of reverb impulses, enabling more realistic spatial effects. The included SoftGateLinked version supports stereo processing, ensuring balanced noise reduction across both channels. This plugin is ideal for producers and sound designers seeking refined noise control without sacrificing natural audio decay.
