  • Wide support. The plugin is available in VST3 on Windows and Mac, and AU on Mac, for use in most major DAWs. AAX support is coming soon. M1/M2 Macs are natively supported.
  • Low CPU usage. The signal processing algorithms used have been selected carefully and optimized for x86/x64 and ARM processor cores, for consistently low overhead. Use it on every track!
  • Negligible latency. The use of minimum-phase filters means the plugin can do its work without adding any noticeable delay.
  • Elegant, responsive interface. Polyspectral MBC features clear, intuitive parameter adjustment and a real-time spectral display, so you can see exactly what it's doing to your frequency spectrum and dynamics.
  • Sonically transparent. The compression algorithm was designed with mastering in mind. It is extremely transparent and will not give the mix any undesired color.
  • Flexible bus layout. All common speaker layouts, as well as Ambisonic formats, are supported transparently.


This free demo version of the plugin is identical to the full version, except that its output is periodically replaced with silence.
