This folder contains all measurements in AutoEQ and tools to crawl them from the supported databases.

Additional Python packages are required for processing the measurements:

python -m pip install -U -r measurements/dev-requirements.txt

Measurement crawlers require Google Chrome installed and ChromeDriver binary in the measurements folder (or anywhere in the PATH).

Measurement crawlers also require C++. This should be installed by default on Linux but on Windows you need to install Microsoft Visual Studio build tools for this. https://visualstudio.microsoft.com/downloads/ -> "Tools for Visual Studio 2019" -> "Build Tools for Visual Studio 2019".

oratory1990 and Innerfidelity require Ghostscript installed: https://www.ghostscript.com/download/gsdnld.html

Numerical data for Crinacle's measurements is not available in this repository. Crinacle has Patreon and a certain subscription tier unlocks the raw numerical measurement data. If you are a patreon and have access to the Google Drive containing the measurement files, you can download the data to crinacle/raw_data folder. Download the IEM "IEM Measurements (TSV)", legacy headphone measurements "Legacy Data (Ears + 711)" and the new GRAS headphone measurements "FR Data (CSV)" separately. The directory structure should be:

measurements
    crinacle
        raw_data
            FR Data (CSV)
                99 Classic L1.txt
                99 Classic L2.txt
                ...
            IEM Measurements (TSV)
                1 Plus 2.2 L.txt
                1 Plus 2.2 R.txt
                ...
            Legacy Data (EARS + 711)
                A990Z R1.txt
                A990Z R2.txt
                ...

update_measurements.py will then process these files and create AutoEq compatible CSV files in crinacle/data organized by headphone type.

1. Remove measurements that have updates
2. Prune results: python results/prune_results.py
3. Crawl new measurements: python measurements/update_measurements.py --prompt
4. Run results update: python results/update_results.py --new_only
5. Update result indexes: python results/update_indexes.py
6. Add files to git: git add results measurements/*/data measurements/*/name_index.tsv
7. Commit: git commit -m "New measurements with pre-computed results."
8. Push: git push
