AutoEq

# AutoEq
AutoEq is a tool for automatically equalizing headphones.

Go to **[autoeq.app](https://autoeq.app)** to get started.

This Github repository now mainly serves developers. The contributions of this project are:
* Web application for easily equalize and tweak headphone frequency responses without needing to install anything
* Library for working with (headphone) frequency responses and optimizing parametric equalizers
* [PyPi package](https://pypi.org/project/autoeq/) for installing the library on your projects
* Collection of headphone [measurements](./measurements) as numerical data from
[oratory1990](https://www.reddit.com/r/oratory1990/wiki/index/list_of_presets/),
[crinacle](https://crinacle.com),
[Innerfidelity](https://www.stereophile.com/content/innerfidelity-headphone-measurements),
[Rtings](https://www.rtings.com/headphones/1-5/graph) and legacy
headphone.com measurements (which are not the same as what the company produces today).
* Collection of different headphone frequency response [targets](./targets) as numerical data
* Pre-computed equalizer settings in [results](./results), although these should not be used by normal users since
**[autoeq.app](https://autoeq.app)** exists

### Updates
**2023-10-29** AutoEq version 4.0.0. Improved and unified naming conventions across the project. Cleaned up obsolete
files and reorganized directory structure. Completely reworked database management tools.

**2022-05-14** Web application. Reorganized measurements and results.

**2022-10-30** Restructured the project and published in PyPi. Source code moved under [autoeq](./autoeq) directory and 
command line usage changed from `python autoeq.py` to `python -m autoeq` with underscores `_` replaced with hyphens `-`
in the parameter names. 

**2022-09-18** Parametric eq optimizer reworked. The new optimizer supports shelf filters, has a powerful configuration
system, run 10x faster, has limits for Fc, Q and gain value ranges and treats +10 kHz range as average value instead of
trying to fix it precisely.

## Usage
AutoEq produces settings for basically all types of equalizer apps but does not do the equalization itself. You'll need
a different app for that. Go to **[autoeq.app](https://autoeq.app)** and select your equalizer app of choice. Quick
instructions for importing the produced settings will be shown there.

## Command Line Use
In addition to the web application, AutoEq can be used from command line (terminal). This is advanced use mainly
intended for developers. The following instructions apply for command line and Python interface use.

### Installing
- Download and install Git: https://git-scm.com/downloads. When installing Git on Windows, use Windows SSL verification
instead of Open SSL or you might run into problems when installing project dependencies.
