Equalizer APO is a parametric / graphic equalizer for Windows. It is implemented as an Audio Processing Object (APO) for the system effect infrastructure introduced with Windows Vista.
Features:

  • virtually unlimited number of filters
  • works on any number of channels
  • very low latency, which makes it suited for interactive applications
  • low CPU usage
  • modular graphical user interface
  • VST plugin support
  • integrates into Voicemeeter (www.voicemeeter.com)

Equalizer APO is best used in conjunction with Room EQ Wizard (www.roomeqwizard.com ), because it can read its filter text file format.
