Before reading on, note there's scam website under the peace equalizer name. Only this site here on SourceForge is the actual website by me, Peter Verbeek.
Peace equalizer is a Windows PC interface for Equalizer APO http://sourceforge.net/projects/equalizerapo. Besides an system-wide audio equalizer on your Windows PC, Peace has an effects panel for balance, crossfeeding, delay, etc., a graph window and much more.
In short: Peace is an equalizer and audio mixer for all your PC software on any Windows version from Vista to 11.
Your configuration (e.g. EQ, preset, profile) can be saved and activated again by 1 click, hotkey, tray or desktop shotcut.
Install by running downloaded PeaceSetup.exe. Equalizer APO has to be installed first. After a Windows update a re-install of Equalizer APO might be needed.
Also, all Peace apps have a code signing certificate by Certum, Asseco.

5 out of 5 starsHad to join up just to compliment the devs on this, this really saved my life! I needed a front-door EQ for external Windows inputs and it works like a bomb! First time install, Windows 11 vanilla on HP Pavilion laptop. Recording an audiobook, needed to EQ my funky voice, using a Volt1 audio interface, EQ passes all the way through to audiobook recorder engine, amazing. Didn't get any Windows Defender or other virus blocker popups, the gods sometimes smile, thank God. Well done all of you from a veteran corp I.T. dog (leaving Support rating blank as I haven't had any yet).Reply from Peace Equalizer, interface Equalizer APOPosted 2026-10-28

5 out of 5 starsI know this is just the interface, but aside from being brilliant in terms of practicality and features, it is the most powerful equalizer I know of. Thanks for such a masterpiece.Reply from Peace Equalizer, interface Equalizer APOPosted 2026-09-13
