Features

  • Automatic gain control audio plugin (VST3 & AU)
  • Adjustable target level and response time
  • Input gating with dynamic threshold
  • Alt mode for immediate response without hysteresis

atkAutoGain is an automatic gain control audio plugin that helps maintain a consistent signal level in real-time. It is especially useful on speech, dialogue and other voice-driven material where overall level needs to stay controlled without constant adjustment. Input gating combines a manual threshold with a dynamic relative threshold that follows the signal, helping gain adjustment react to intentional content while ignoring low-level background sound. Adjustable target and timing controls make it easy to balance steady results with natural dynamics in both live and post-production work, while Alt mode allows more immediate level tracking when hysteresis is not desired.

Parameters

  • Threshold: atkAutoGain only operates when input signal exceeds this level.
  • Target: Desired output level. Gain adjusts to bring signal to this level.
  • Time: Smoothing speed. Controls how quickly gain adjusts to level changes, and hold time before dynamic threshold starts decaying.
  • Alt: Enables immediate response without hysteresis. Useful for content requiring precise level tracking. When off, hysteresis reduces constant gain adjustments for content with natural level variations.

Threshold Guideline

Guideline shows dynamic threshold. atkAutoGain only operates when signal exceeds both manual and dynamic thresholds, ensuring only intended signal gets adjusted. If signal stays below dynamic threshold for duration set by Time parameter, dynamic threshold starts decaying.

Usage

  1. Set Threshold to match intended input signal level
  2. Set Target to desired output level
  3. Adjust Time for faster or slower gain riding

Notes/Tips

  • Use limiter (such as atkSpeechLimiter) after atkAutoGain to prevent clipping on transients and loud peaks.
  • If AutoGain pumps up quiet parts, or misses low-level intended signals: adjust threshold.
  • If low-level intended signals are not boosted: lower threshold.
  • AutoGain does not explicitly target any loudness standard, but results are close to LUFS scale.
