Spectral Sidechain

What it does

A classic sidechain compressor turns the whole target down. Spectral Sidechain only ducks the frequencies the trigger actually occupies, inside a range you choose.

  • Kick carves room in bass without dropping the entire bass level.
  • Vocals can sit in a dense bed without obvious pumping.
  • Active range keeps the effect limited to the frequencies that matter.

Key controls

  • Sensitivity controls when ducking starts.
  • Depth controls the maximum reduction.
  • Attack and Release shape the movement.
  • Range Low and Range High define where ducking is allowed.
  • Mix and Output control blend and level.
