Professional Gate Demo

Accurate noise gate with mathematical signal processing

About Professional Noise Gates

A noise gate attenuates signals below a set threshold using precise envelope control. This demo implements accurate mathematical models including exponential attack/release curves, hold timing, hysteresis to prevent chattering, and variable range control.

Advanced Parameters:

  • Threshold: Gate opens above this level (dB)
  • Attack: Exponential opening time (0.1-10ms)
  • Release: Exponential closing time (10-1000ms)
  • Hold: Minimum open duration (0-100ms)
  • Range: Attenuation depth when closed (-∞ to 0dB)
  • Hysteresis: Prevents rapid switching (3dB)

Mathematical Features:

  • Proper dB to linear conversions (10^(dB/20))
  • Exponential envelope calculations
  • Hold timer implementation
  • Hysteresis-based threshold switching
  • Real-time transfer function visualization
  • Accurate gain reduction metering

Professional Implementation Notes

Threshold Setting

Set 3-6dB above noise floor. Use hysteresis to prevent chattering. Monitor input level during soundcheck for optimal placement.

Envelope Timing

Fast attack (0.1-1ms) preserves transients. Moderate release (50-200ms) avoids pumping. Hold time prevents cutting between syllables.

Range Control

-∞dB for complete noise elimination. -20 to -40dB for natural-sounding background reduction while preserving room ambience.
