Equalizer APO 64-bit v0.9.1

Open source
Vista / Win7 / Win8
Equalizer APO (64-bit) is a parametric equalizer for Windows. It is implemented as an Audio Processing Object (APO) for the system effect infrastructure introduced with Windows Vista.

  • virtually unlimited number of filters
  • works on any number of channels
  • very low latency, which makes it suited for interactive applications
  • low CPU usage

  • Windows Vista or later (currently only Windows 7, 8 and 8.1 have been tested)
  • Sound card driver must support APOs (this includes most onboard sound drivers)
  • The application must not bypass the system effect infrastructure (possible by using special APIs like ASIO)
