Peace GUI for Equalizer APO: What It Is & When to Use It

Peace is the popular graphical interface for Equalizer APO. How it relates to HeSuVi — and whether you need both.

What Peace Actually Is

Peace (Peter’s Equalizer APO Configuration Extension) is a Windows GUI for Equalizer APO — the same audio engine HeSuVi builds on. Where HeSuVi’s interface focuses on virtual surround profiles, Peace focuses on equalization: sliders, graphs, presets, and per-device profiles.

Peace vs HeSuVi: Different Jobs

• HeSuVi: 150+ HRIR surround profiles, channel configuration, basic EQ, AutoEq integration. The surround toolkit.
• Peace: full-featured parametric/graphic EQ interface, automation, hotkeys, many EQ presets. The EQ workstation.
• Both are free front-ends driving the same Equalizer APO engine underneath.

Do You Need Both?

Usually no — pick the interface matching your priority. HeSuVi already includes EQ and AutoEq, which covers most users. Consider Peace instead if you want deep EQ automation (per-app profiles, hotkey switching) and do not care about virtual surround — or run Peace instead of HeSuVi’s UI, not alongside it, to avoid config conflicts.

Can They Run Together?

Technically they both write Equalizer APO config files, so running both UIs risks overwriting each other’s settings. If you experiment: back up your config folder first (EqualizerAPO\config), use one interface at a time, and know which one ‘owns’ the current config.

Frequently Asked Questions

Is Peace better than HeSuVi?

Different tools: Peace is the better pure-EQ interface; HeSuVi is the virtual-surround toolkit. Most gamers wanting surround pick HeSuVi.

Do I need Peace if I have HeSuVi?

No. HeSuVi includes EQ and AutoEq already. Peace is an alternative, not a requirement.

Is Peace free?

Yes — Peace is free software, like Equalizer APO and HeSuVi.

Can Peace do virtual surround?

Not like HeSuVi — Peace has some channel mixing effects, but HeSuVi’s 150-profile HRIR library is in another league for surround.
