Is a chaotic track starting to get to you? Maybe you should make it a little more "Smoov". Smoov is a soft, clean and transparent sounding program-dependent compressor. It takes inspiration from hardware compressors of the past with a focus on peak detection, meaning that it can quickly and effortlessly react to incoming signals and blend them in with the surrounding audio field. When a busy track needs taming, Smoov softly settles your tracks.

The compressor uses a program-dependent envelope influenced by old hardware making the compression sound smooth and dynamic. The peak detection means that Smoov detects the actual amplitude of a signal, resulting in an extremely fast response to tame and control anything that is thrown at it.

You've got a big, groovy track you think you're happy with, but you have to ask yourself... "Is it Smoov?"


Available as: VST3 for Windows, AU + VST3 for MacOS, AUv3 + IAA + standalone app for iOS and iPadOS. Please ensure your DAW supports one of these formats.


Versatile Ratios

Smoov gives 4 styles of ratios to choose from:

  • 0.1:1 to 0.9:1 for expansion and gate effects.
  • 1:1 to 20:1 for standard compression.
  • ∞:1 for infinite limiting compression.
  • -20:1 to -1:1 for over-compression effects.

More than just typical compression, Smoov has a variety of different ratio settings to provide different effects to shape the dynamics.


Sidechain Control

Smoov's sidechain can either use the internal signal to calculate the gain reduction or an external signal via the sidechain bus input to calculate gain reduction.

In both these circumstances the sidechain signal can be filtered so that the compressor only responds to specific frequencies. This filtering can in turn be shaped using the Low Pass Filter (LPF) and High Pass Filter (HPF) knobs.

The Low Pass Filter and High Pass Filter knobs both range from 1Hz to 22000Hz.
