For video game developers, Polyspectral MBC is available as a plugin for Audiokinetic's Wwise audio middleware. It has been carefully designed specifically for real-time mastering of a game's audio mix.

Use cases

The Polyspectral MBC plugin can be placed anywhere in the signal chain in a Wwise project, and its settings can be used to improve your game's sound in many different ways:

  • Apply gentle, natural-sounding compression to the full game mix, to get a fuller, more detailed, more “glued” sound. Hear more of your music and ambience without sacrificing intelligibility of voice and sound effects.
  • Use it as a final-stage limiter. Ducking only the loudest parts of the content avoids unnatural changes in unrelated frequency bands.
  • Use it on an interactive music mix to achieve levels of polish and cohesion previously possible only in linear, non-interactive music production.
  • Quickly adjust your EQ and dynamics to suit different platforms or different output devices. With minimal effort your work can be tailored for laptop or phone speakers, or for a world-class theater sound system.


  • Wide platform support. The plugin has been built to work in all modern game platforms—desktop, mobile, and console.
  • Flexible bus layout. All common speaker layouts, as well as Ambisonic formats, are supported transparently. LFE and Center channels can be excluded from processing if desired.
  • Low CPU usage. The signal processing algorithms used have been selected carefully and optimized for x86/x64 and ARM processor cores, for low overhead on every platform.
  • Negligible latency. The use of minimum-phase filters means the plugin can do its work without adding any noticeable delay to the output.
  • Elegant, responsive interface. With clear, intuitive parameter adjustment and a real-time spectral display, Polyspectral MBC sets a new interface standard for game audio plugins.
  • Sonically transparent. The compression algorithm was designed with mastering in mind. It is extremely transparent and will not give the mix any undesired color.
