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.

I 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

Thanks for reviewing Peace. -
This is the best free equalizer on the internet with preset per device function, the features is also rich. Previously im using the stock B&O Equalizer, and compared to this, peace equalizer is far-far better. loved it so much! thank youReply from Peace Equalizer, interface Equalizer APOPosted 2026-08-19

Thanks for your nice review :) -
Peace Equalizer makes it easier. God bless the developer for having to put lipstick on the pig EAPO is in terms of GUI. Not perfect but nice. Still leaves headphone eq in the realm of hobbyists. EAPO is clunky, clumsy and requires hours to become proficient tbh. I have work. Family. Other hobbies. Made easier enough to put this on top. A less clunky program on top of a clunky program just to listen to music. What fun, said no one, ever. I can't find a one-time download, fire and forget pre-loaded with tons of eq settings already incorporated like Qudelix can do. 🤷♂️Reply from Peace Equalizer, interface Equalizer APOPosted 2026-07-14
Thanks for your elaborate review. I'm not sure what you mean 'tons of eq settings'. Peace has plenty, most of them hidden under the + button above the list of configurations. Also, Peace includes about 10,000 headphones EQ's under the AutoEQ button.
