# AutoEQ to targets ( )

The simplest way to use EQ is by using AutoEQ, a project that aims to create automatic EQ presets using measurements and a specific target. There are various implementations of AutoEQ: in most cases, AutoEQ aims for the HarmanIE 2019 target. The following sections cover most cases, and also have pros/cons added.
AutoEQ has a wiki that explains how it functions, but in short, it aims to match the FR of a model to a chosen target in the range of 20Hz to 10kHz. For the guide, both the lower and upper limits will be used.

# AutoEQ website

AutoEQ.app is a web application for the AutoEQ project, and has additional features for further tweaking and customization.

Find your IEM model
Select the EQ app you plan on using
2*. Under the Advanced option in the Profiles tab, select your target of choice
Download the file
Import/use the file in your EQ app of choice.

Pros	Cons
Live demo'ing	Somewhat overwhelming/convoluted at first
Customization available	Customization can lead to bad results
Wide EQ app support	Somewhat limited model selection

# EQ app

Several EQ apps have also implemented the AutoEQ project, such as Poweramp on Android and PeaceGUI on Windows. In this case, simply pick the IEM model you have and the preset should apply automatically.

Find your IEM model and apply the preset

Pros	Cons
Easy to use	Somewhat limited model selection
No additional installation

# Squigs

Squig databases also have an Equalizer tab that implements AutoEQ. To use it, select the target that you want (under the FR graph), then select your IEM model in the Models tab, ensuring that only the chosen target and IEM are on the FR graph. In the Equalizer tab, find the AutoEQ option, adjust the range (maximum upper limit around 10kHz as specified by the AutoEQ project), generate the preset, then export it accordingly.

Select the wanted target under the FR graph
Select the IEM model in the Models tab, ensuring that only the chosen target and IEM are on the FR graph
Find the AutoEQ option in the Equalizer tab
Adjust the range (maximum upper limit around 10kHz as specified by the AutoEQ project)
Generate the preset
Export the preset accordingly

Pros	Cons
Extensive selection of models and targets	Export only exports the filter values which need to be manually re-input in whatever EQ app is being used
Customization available	Default range extends to 15kHz, far above what is recommended
	Can be inefficient since it only uses peak filters

# Wavelet

Wavelet is an Android app that has AutoEQ implementation and allows for system-wide equalization.

Enable Wavelet
Choose your IEM model in the AutoEQ section
2*. If needed, import presets made in squig.link or AutoEQ.app

Pros	Cons
Easy to install and use	No customization possible
Presets available from other sources	Hassle when making a new preset
