Goals¶

Automatically analyse thousands of tracks in FLAC and DSF
Extract and normalise metadata from the files
Calculate the DR value per track
Build a SQLite database
Generate visualisations and conclusions from the data

What's included¶

Analysed library¶

The collection includes material from:

CD
SACD / DSF
XRCD
SHM-CD / SHM-SACD
other audiophile editions and personal rips

Processed data¶

Each track may include:

format
artist
album
title
year
genre
DR value

Insights → observations and notes on the results
Methodology → how data is extracted and processed
Pipeline → technical flow of the project
Charts → visualisations generated from the database
Conclusions → analytical synthesis of the collection

Project philosophy¶

This site does not aim to be a universal database or a normative reference on mastering. Its goal is more modest — and perhaps more interesting:

to document, explore and understand a specific music collection from a technical and audiophile perspective.

Status¶

The project is in continuous evolution. Metadata will be corrected, cleaning criteria refined, and new visualisations added over time.
