Compactor

Kilohearts

Compactor is a surgical ducking compressor that uses sidechain ducking to control one signal based on another at sample-rate accuracy. It enables precise level ducking and mixing control without sacrificing loudness, and can also be used for creative distortion effects. Available as a free plugin that works as a standard plugin or snapin in the Kilohearts modular ecosystem.

Key Features

01Sidechain ducking with sample-rate accuracy
02Three detection modes: PEAK, ISP (inter-sample peaks), and RMS
03Attack, Hold, and Release controls for envelope shaping
04Range parameter to scale sidechain sensitivity from 0-100%+
05Stereo correlation control for independent left/right processing
06Threshold-based level limiting and silencing

Things to Try

  • 01Use PEAK mode for most applications to ensure no transients pass the threshold
  • 02Switch to ISP mode for maximum accuracy when detecting inter-sample peaks
  • 03Use RMS mode for smoother, more musical response based on average signal power
  • 04Set Range below 100% to ignore quieter input levels and trigger ducking only on strong signals
