What is peace-equalizer-apo?

This repository provides a graphical interface for a Windows audio tool called Equalizer APO. Equalizer APO is a system-wide audio processing engine, meaning it applies sound adjustments across everything playing on your computer at once: music, games, video calls, and streaming apps. Peace is the visual front end that makes Equalizer APO easier to configure without editing configuration files by hand. With Peace installed on top of Equalizer APO, you can adjust audio using a parametric equalizer or a graphic equalizer, import preset profiles tuned for thousands of specific headphone models through a feature called AutoEQ, and create custom sound profiles. The README mentions presets from known headphone measurement databases. You can apply bass boost, configure per-application settings, and switch between profiles. Installation is Windows-only, optimized for Windows 11. The steps are: install Equalizer APO first as a prerequisite, then download and extract the Peace archive from the releases page, run the executable as an administrator, and follow the setup guide. The troubleshooting table in the README covers common issues such as the application not starting, audio distortion, profiles failing to load, and Windows 11 compatibility errors. The repository notes this is for educational and personal use only, and the authors disclaim responsibility for audio issues or system changes. The license is MIT.
