Peace Equalizer, interface Equalizer APO

System-wide PC Audio Equalizer and Effects app for Windows 7 to 11

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. YouTubers: Please mention Peace Equalizer in your video description. Thanks to all contributors.
