FluidEQ vs Peace Equalizer
Peace Equalizer alternative
Peace is a capable window onto Equalizer APO, and it needs APO underneath. FluidEQ brings an engine of its own, so nothing else has to be installed first, and it can still run on Equalizer APO when you want to keep its commands and plugins.
Side by side
Peace and Equalizer APO are two programs that work as one. FluidEQ is one program that needs neither.
| FluidEQ | Peace Equalizer | |
|---|---|---|
| Price | Free, with every sound feature. FluidEQ Plus, optional, adds visualizers | Free, with an optional donation |
| Source code | Open source, GPL-3.0 | Open source, GPL-2.0 |
| How it reaches your sound | Its own engine, inside Windows’ audio service and after your sound card’s effects — or Equalizer APO, if you choose it | Through Equalizer APO, which has to be installed first: Peace writes APO’s configuration |
| Equalizer | Parametric, up to 128 bands with every filter type, under Bass, Mid and Treble knobs | Up to 31 sliders per speaker, each with its own frequency, gain and Q, in peak, shelf, pass, band, notch and all-pass types |
| Headphone correction | 6,229 headphone models, built in and offline | An AutoEQ list of about 10,000 headphone EQs |
| Effects | A 10-stage DSP rack on everything you hear, with surround on headphones in its Room | Up- and downmixing, crossfeed, bass and treble, and channel routing; VST plugins through APO’s Configuration Editor |
| Headphones and speakers | Each output keeps its own tuning, and gets it back when you switch to it | A configuration can be stored with a device, and switched by hotkey |
| Installing | One Windows permission and no reboot on its own engine | Install Equalizer APO, then Peace; on Windows 10 and 11 it may need administrator rights |
| Runs on | Windows 10 and 11 | Windows 7 to 11 |
When Peace Equalizer is still the better choice
You tune surround speakers one by onePeace gives each of up to nine speakers its own sliders, with up- and downmixing and routing between channels: a depth of per-speaker control built for 5.1 and 7.1 setups.
You switch presets from a keyboard or a MIDI controllerPeace maps each configuration to a hotkey and can take a MIDI controller. FluidEQ has neither: its tuning follows your output instead.
