AUpresetConverter

Here are set of utility to manipulate an EQ generated by REW or in APO format.

A common use case on macOS is that when you have done a room calibration, you are getting some EQs generated by REW, you may have to manually copy the EQ into AUNBandEQ. It takes 5 minutes to copy the parameters, but it is very error-prone and boring.

Another use case is to use an EQ generated by autoEQ for your headphone. You feed it to the tool, and you get a preset.

After creating the EQ in the format that matches your software or your hardware, you can easily import it in one click.

How it works?

The easiest way is to use eqconverter.spinorama.org/

You can also run it locally:

Installation

python3 -m venv venv
source ./venv/bin/activate
pip3 install -r requirements.txt
pip3 install -r requirements-dev.txt
npm i .

Run it

./eq2eq.py

will display usage.

AUNBandEQ

./eq2eq.py -input eq.txt -format aupreset

will copy the AUpreset to the standard output.

You may want to copy it where most DAW can find it:

./eq2eq.py -input eq.txt -format aupreset -install

you can redirect to a file with the -output flag.

./eq2eq.py -input eq.txt -output eq.aupreset

will copy the AUpreset where DAWs(1) expect to find them (2).

• (1) at least Reaper and Logic will
• (2) ~/Library/Audio/Presets/Apple/AUNBandEQ

REW TotalMix EQ

./eq2eq.py -input eq.txt -format rmetmeq -output eq.tmeq

You can then import the eq in TotalMix.

Running the App

In development mode

Start the backend:

export EQCONVERTER_ENV="dev"
python3 ./backend.py &

and then a reverse proxy for the frontend, either

python3 ./scripts/debug_server.py &

or

mkdir -p logs
nginx -p `pwd` -c ./etc/nginx-dev.conf

In production

If you want to expose it on the internet, you can use a reverse proxy, you will need a domain name and the associated certificate. In the etc directory, you will find a config file for nginx (the reverse proxy) and a systemd service config file.

the systemd file should go to ~/.config/systemd/user, edit the path, and then, you can run it via:

systemctl --user enable eqconverter.service
systemctl --user start eqconverter.service
systemctl --user status eqconverter.service

The nginx file should go to /etc/nginx/site-available. Look at the nginx manual for more details.
