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
Every result is reviewed before it's written. 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.
