What TagVault does

Everything your library
deserves

Purpose-built for music collectors, audiophiles, and DJs who demand accurate, complete metadata across large libraries.

🎵
Audio Fingerprinting
Identifies tracks by their actual audio content — not by filename or existing tags. Works even on unlabelled, mislabelled, or incorrectly named files.
🔍
6-Source Metadata Pipeline
Queries multiple independent databases in sequence. Each source fills gaps left by the previous — cross-referencing to find the most accurate title, artist, year, and label.
🎛
BPM, Key & Energy
Professional-grade BPM detection, musical key in Camelot notation, and energy scoring — all computed locally on your machine. No audio ever leaves your device.
✍️
Tag Writing
Writes ID3, Vorbis, APE, and WAV tags to MP3, FLAC, WAV, AIFF, and DSF files. Tags written once, correctly, with your approval.
📤
DJ Software Export
Export your analysed library directly to Rekordbox XML, Serato M3U, CSV, or Excel. Filtered exports included — export exactly what you need.
🔒
Review & Approve
High-confidence matches are tagged automatically, so you're not reviewing thousands of tracks by hand. Anything uncertain lands in your Review queue for approval first. Lock approved tracks so manual edits are preserved — batch approve, undo, and re-analyse at any time.

What you get

From chaos to
complete

TagVault transforms unidentified, poorly-tagged, or incomplete music files into a fully enriched, organised library — ready for any workflow.
