Free DownloadEqualizer APO is a parametric equalizer for Windows. It is implemented as an Audio Processing Object for the system effect infrastructure introduced with Vista. It doesn’t use ASIO and doesn’t require any tricks to get it to work. Any Windows audio will be equalized including Itunes, Windows Media Player, games, anything so long as it doesn’t bypass the Windows driver. IE WASAPI or ASIO would bypass the equalizer as well. While Equalizer APO is a really awesome piece of software, it lacks a configuration GUI. You have to download and install a third-party GUI program like PC Equalizer or PEACE that takes the command-line hassle off you.
