what is peace-equalizer-apo fr?

This repository is an unofficial distribution of Peace Equalizer, a graphical interface for a free Windows audio tool called Equalizer APO. Equalizer APO is a system-wide audio processor that runs quietly in the background and modifies sound before it reaches your headphones or speakers. On its own it has no visual controls, so Peace provides the interface that lets you actually see and adjust what is happening. An equalizer lets you change how different frequencies of sound are balanced. Boosting low frequencies makes bass sound heavier. Adjusting mid and high frequencies can make voices clearer or reduce harshness. Peace offers both a parametric equalizer, which gives precise control over specific frequency bands, and a 31-band graphic equalizer, which works like the sliders you might see on a stereo. There is also a real-time frequency graph so you can see the shape of your adjustments visually. The tool includes built-in support for AutoEQ, a community project that has measured and created correction profiles for over a thousand headphone models. If your headphones have a known profile, you can load it and automatically correct their sound signature. Separate presets are included for gaming, music, movies, and voice use cases, and you can save different configurations per device or per application. Installation requires first installing Equalizer APO from its official source, then installing Peace on top of it, and restarting the PC. The repository notes that this is an unofficial distribution and that the original Peace software was created by a developer known as peverbeek and is hosted on SourceForge. It recommends downloading from official sources when possible.
