Voxengo releases Polysquasher Mastering Compressor v2.0


Voxengo has announced the release of version 2.0 of Polysquasher - a major new revision of the mastering compressor plug-in, now available for Mac OS X and Windows (incl. x64) in VST and AudioUnit plug-in formats.

PolysquasherVersion 2 features the following improvements over version 1:

  • Compressor mode editor.
  • Linear-phase oversampling.
  • Multi-channel support.
  • Multi-platform support.
  • Undo/redo.
  • Routing matrix.
  • Preset manager.
  • User interface coloration.
  • User interface re-scaling.
  • Channel grouping.
  • Plug-in instance naming.
  • Bypass switch.

Polysquasher is a mastering compressor that was designed with one main goal: to be transparent. Polysquasher achieves its goal by using a unique compression algorithm which requires a small number of parameters – basically threshold and ratio only – making this compressor simple to use. More advanced settings are hidden in the "compressor mode editor" panel where you can create your own compressor modes that can be easily recalled later.

Polysquasher is best used as a finishing compressor inserted in the chain before the final mastering limiter.


  • Transparent compression sound.
  • Real-time gain reduction graph.
  • 8 built-in compressor modes.
  • Compressor mode editor.
  • Multi-channel processing.
  • Internal channel routing.
  • Channel grouping.
  • Up to 8x linear-phase oversampling.
  • 64-bit floating point processing.
  • Preset manager.
  • Undo/redo history.
  • A/B comparisons.
  • Contextual hint messages.

Polysquasher can be loaded into any audio host application that conforms to the VST or AudioUnit plug-in specification. Plug-in is compatible with Windows XP, Windows Vista (32- and 64-bit) and Mac OS X 10.4.11 and above (Intel and PowerPC) computers (2 GHz dual-core or faster processor with at least 1 GB of system RAM recommended). A separate binary distribution file is available for each target computer platform for each plug-in format.
