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.

Requirements:
- Windows Vista or later (Windows 7 - 11 have been tested)
- CPU architecture x64 (64 bit), x86 (32 bit) or ARM64 (on Windows 10/11)
- applications must not bypass the system effect infrastructure
(APIs like ASIO or WASAPI exclusive mode can't be used)

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

Please have a look at the Wiki (http://sourceforge.net/p/equalizerapo/wiki/) for instructions on installation and configuration
