    Equalizer APO

    A system-wide equalizer for Windows 7 / 8 / 8.1 / 10 / 11

    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
