I went ahead and created this app because I'm a huge fan of AutoEQ. Sadly, every music player out there is paid and doesn't really have the full functionality of AutoEQ for every pair of headphones, so I went ahead and built it myself.

The tool uses two EQs: one is for the target curve, and the second one is for me as the user to fine-tune it to my liking, just how the AutoEQ developer advises to do.

I have a lot of music that's downloaded from YouTube and converted to MP3, and YouTube Music just didn't cut it—especially with how bass-heavy most headphones are nowadays. Plus, with Pixel devices being crap right now, I didn't want to stay with Android. I came over to iPhone for good now (or at least until there's a good Pixel again), so I really miss Wavelet, and it shows in what I built.

I hope I don't get shamed for doing this, like I did in other forums.

I have been an AutoEQ nerd ever since Wavelet came out, so I'm a big fan and enthusiast. I really appreciate the concept, and I'm incredibly grateful to oratory1990 and the many others who have done so much for the community.

I used to use Peace EQ, but it isn't very user-friendly or robust. I wanted to make something cleaner, more straightforward, and highly user-friendly. Personally, I don't see anything wrong with what I've built, but I would love for you to test it. Any feedback you can provide would be awesome and highly appreciated. It does not have community presets. You are more than welcome to download them from AutoEQ or squiglink and then import them. It does have a second set of 10 bands that you can adjust to your liking, but I would suggest the target bands not be adjusted after importing the .txt file.

A clean install of APO is recommended !

To get started:

1. You must have APO installed already. Just follow the standard instructions to set it up.
2. Select the outputs you want to adjust.
3. Reboot your system.
4. Install the program I am sharing here today.

It is totally free, and I'm not asking for anything in return. I just want your feedback and any feature requests you might have. If they fit my vision for the project, I will probably implement them.

Please let me know what you think, and enjoy!

A free Windows app for system-wide parametric EQ via Equalizer APO.

Made for audiophiles who want to:

1. Load a target curve (AutoEQ / Squiglink / measurement-based correction)
2. Keep a separate personal EQ for taste
3. Save and switch targets without re-importing every time

Not a Peace replacement. Peace is a full APO control panel. This is a focused target + personal workflow tool.

Download: [your installer link]

Requires: Windows 10/11 + Equalizer APO (https://sourceforge.net/projects/equalizerapo/)

link to the app -> https://drive.google.com/file/d/1MawGqMy5WdN4tv2Hw57XnXXhBcyOBOjs/view?usp=drive_link

───

What it does

• Writes Equalizer APO config (ParametricEQ.txt) so EQ is system-wide (on devices where APO is enabled)

• Target layer: 10 peak bands + preamp (correction)

• Personal layer: 10 peak bands + preamp (your taste — never wiped by import)

• Target library: import once → name it → pick from a dropdown later

• Full setup profiles: optional save of Target + Personal together

• Live frequency graph (20 Hz–20 kHz, ±20 dB), layers + combined

• Master EQ On/Off, live apply, dark/light + accent themes

Audio chain: apps → Windows device → Equalizer APO → this app’s config → headphones.

The app does not process audio by itself; APO does.

───

Install if you do not have Equalizer APO

1. Install Equalizer APO from SourceForge.
2. In Configurator, check the playback device you actually use.
3. OK / reboot if asked.
4. Install Parametric EQ (setup .exe).
5. If SmartScreen appears: More info → Run anyway.
6. Open the app → leave EQ On green → follow “How to use” below.

If APO is not enabled on that device, the app will run but you won’t hear EQ.

───

Install if you already have Equalizer APO

1. Confirm in Configurator that your current Windows output device still has APO enabled.
2. Install Parametric EQ.
3. If you use Peace:• Close Peace while using this app (it can rewrite config.txt).• This app uses Include: ParametricEQ.txt and keeps a backup:

config.txt.backup-before-parametriceq

• To go back to Peace: restore that backup or set Include: peace.txt again.

4. Open Parametric EQ and use as below.

How to use

Everyday workflow

1. Target curve tab → Import new…• Load an AutoEQ/Squiglink/APO .txt, or paste lines like:

Preamp: -6.2 dB

Filter 1: ON PK Fc 1000 Hz Gain 2.5 dB Q 1.41

Filter 2: ON PK Fc 3000 Hz Gain -3.0 dB Q 2.00

2. Check the graph and Target gains (should not all be 0.0).

3. Save target with a name (e.g. “AirPods Max Rtings”).

4. Personal taste tab → tweak gain/Fc/Q to what you like.

5. Later: open Target library dropdown and pick another saved curve — personal stays.

Optional: Full setup → Save setup stores Target + Personal as one named profile.

Layers (why this exists)

Import / library → TARGET (filters 1–10) = headphone correction

You tweak → PERSONAL (11–20) = preference

Both sum → Equalizer APO

• Import only updates Target.

• Switching targets does not reset Personal.

• Each layer has its own preamp and on/off switch.
