The main screen shows a series of sliders. Each slider matches a specific sound frequency. Move a slider up to increase the volume of that frequency range. Move it down to decrease it.
- Frequency bars: The sliders on the left control low bass. The sliders on the right control high treble.
- Presets: Use the preset menu to choose settings tailored for specific needs. Select a profile for speech, movies, or music.
- Saving configurations: Click the save icon to store your current slider positions. You can load these later by choosing the file from the menu.
- Gain control: Use the preamp slider on the right side to adjust the total volume without changing individual frequencies. Avoid pushing this slider too high to prevent sound distortion.
You can keep different profiles for different hardware. Create one profile for your studio headphones and another for your desktop speakers.

- Rename your current setup.
- Select the device from the dropdown menu.
- Click update to save the link between your device and the profile.
The software includes features to refine your experience.
If you want more impact from your movies or games, increase the sliders at the far left side. Do this in small increments to find the balance that suits your hardware.
The graphical interface provides a visual layout of your sounds. You see the curves change as you move the sliders. If you prefer manual control, input the specific frequency values into the fields provided.
The app integrates with sound databases to apply corrections for specific headphone models. This ensures your hardware hits a neutral sound target. Select your headphone model from the import list to apply these professional settings automatically.
Follow these steps if you experience issues with sound quality or app performance.
- No sound: Check that Equalizer APO is installed. Open the configuration editor for Equalizer APO and confirm the checkmark for your device is active.
- Distortion: Reduce the preamp level on the right side of the Peace window. High boost values create digital clipping.
- App won't open: Right-click the shortcut and select run as administrator.
- Windows updates: If a major Windows update occurs, you might need to re-install Equalizer APO to ensure the audio filters load correctly.
Many users start with a V-shaped curve. This means the low and high frequencies are raised slightly, while the middle frequencies are kept low. This makes music sound bright and energetic. For voices, keep the middle sliders higher to gain clarity while watching videos or calls.
The community maintains the data used for the equalizer profiles. You can search for your specific headphone model online to find custom profiles shared by other users. Download these files and use the import button in the application settings to add them to your library.
Regular updates ensure the software stays compatible with the latest Windows versions. Check the download link below regularly for new versions that include interface improvements.
