Site credits

lufs.to is a hand-curated project. These are the people, sources and tools it's built on.

Project

Created, measured and curated by Mastering.to. Every loudness figure on the site comes from audio measured in-house; see Methodology for how.

Credit data

Mastering engineer, studio, label, catalog number, barcode and artist credits are checked against published sources and left blank when they can't be verified.

• Discogs: release, credit and pressing information. Each release page links back to its Discogs entry where one was used.
• Beatport: release and track information for digital-only electronic releases.
• Liner notes, label and artist websites, and printed packaging where they state a credit directly.

Measurement

Loudness (LUFS), true peak, loudness range, dynamic range and short-term maximum are measured with the Mastering.to analyzer following ITU-R BS.1770 and EBU R128. Cover art is shown only to identify the recording measured.
