drtagger
Audiophile metadata tagging for your NAS library
drtagger is a focused metadata editor for high-resolution audio collections. It works directly against your NAS over WebDAV, edits whole albums at a time, and never touches a single audio frame.
Built for lossless
Supports FLAC, WAV and DSF — the formats audiophile rips actually use. Tags are read and rewritten in place; the audio payload is preserved byte-for-byte so MD5 verification still passes after every save.
Album-centric workflow
Open a folder and drtagger parses every track at once, presents the album as a single object, and shows candidate releases from MusicBrainz and Discogs side by side. Multi-disc rips with Disc 1 / Disc 2 / Art subfolders are detected automatically.
Find the exact pressing
Catalog numbers buried in your existing tags are mined as search hints, so Japanese SHM-CDs, MoFi One-Steps and audiophile reissues surface immediately. Tap an artwork scan to read its OBI strip, catalog code or EAN-13 barcode with on-device Vision recognition — drtagger looks the exact pressing up on Discogs in one tap.
Safe by design
Every apply writes a timestamped JSON backup of the original tags to the album folder before anything is rewritten. A built-in restore flow rolls any album back to a previous backup. Writes are atomic (.tmp + MOVE on the server), so a crash mid-save can never leave a half-written file.
Cover art
When the candidate brings a canonical front cover (Cover Art Archive or Discogs primary), drtagger fetches the high-resolution image and replaces your local cover.jpg, backing up the original first.
Deep linking
A drtagger:// URL scheme lets your music player hand off the current album folder for tagging — no copy/paste of paths.
