Tagr ~ Music Metadata Editor

Posted by tom2tec on

Self-hosted web app for browsing, playing, and editing music file metadata. Features a three-panel UI to navigate your library, listen to tracks, and write tag changes directly back to audio files. Built with Next.js, React, Prisma + SQLite, and node-taglib-sharp.

Most metadata editors are either desktop-only, command-line tools, or bloated apps with steep learning curves. If your music lives on a NAS, a server, or a headless machine, editing tags means SSH, mounting drives, or syncing files back and forth.

Tagr takes a different approach:

  • Run it anywhere — Docker, bare metal, your NAS. If it runs Node.js, it runs Tagr.
  • Edit from any browser — No installs, no plugins. Just open a tab.
  • Do one thing well — Browse your library, edit tags, save. That’s it.

Features:

Metadata Editing
  • Edit 40+ metadata fields inline — title, artist, album, year, genre, composer, BPM, lyrics, and more
  • Album art management — view, replace, and upload cover images directly
  • Star ratings (1–5) with a visual widget
  • Support for track/disc numbering, sort fields, catalog numbers, barcodes, and extended tags
  • Read-only display of audio properties (codec, bitrate, sample rate, channels, bits per sample)
Tagr Interface
Music Player
  • Built-in audio player with interactive waveform visualization (WaveSurfer.js)
  • Play/pause, previous/next track navigation
  • Click-to-seek on the waveform
  • Auto-advance to next song
  • Collapsible sidebar player with album art, title, and artist display
Library Browsing
  • Three-panel layout — folder tree, song list, and detail editor side by side
  • Folder tree with hierarchical navigation and real-time search
  • Sorting on any column — title, artist, album, year, duration, bitrate, date added, and dozens more
  • Advanced filtering — text, numeric ranges, date ranges, and boolean filters across all fields
  • Customizable columns — show/hide any of 40+ columns to match your workflow
  • Virtual scrolling and infinite pagination for large libraries

TidyMP3 ~ Metadata Removal Tool

Posted by tom2tec on

This tool removes every kind of trash from your mp3-files. It searches for valid mp3 audiodata-frames and removes everything else. This has the big advantage that it will also remove tags which are in the middle of the file (as is the case with joined tracks) as well as broken frames (half-downloads) and malicious tags (Tag-buffer-overflow bug in WinAMP and Windows XP). Use this tool to cleanup your mp3 files before you add your own tag. No more double tags, or annoying ‘Lyrics’ data containing group names or misspelled song names.

Axone.jar ~ mp3 Examination

Posted by tom2tec on

Axone.jar is a utility allowing you to view all the information available in an MP3 file. This is not to be misunderstood: all the possible information. In the tag version 2 (ID3V2), the information is subdivided into frames and there are many more frames declared than frames actually displayed by MP3 players. Well Axone.jar knows how to display them all, without exceptions and whatever the version!

  • Very classic frames such as title, album, artist, year, genre, track and comment.
  • Other frames displayed by only some MP3 players.
    • the image(s).
    • the composer.
    • the text of the song.
    • volume control (itunes)
  • The frames that are hidden from you (not necessarily with bad intentions).
    • private frames (MusicMatch).
    • encapsulated objects (RealJukebox).
    • abusive comments (iTunes, Mediaplayer, MusicMatch, SoundJam).
    • identification of coding software (LAME, iTunes)
    • the identification of the original CD (LAME)
    • internet links (MusicMatch)
  • Undeclared frames, not understood and therefore clearly hidden from all MP3 players.
  • The other frames usually not used.

Other data

The Lyrics and TAG+ tags, which are completely obsolete, may remain forgotten in certain files. If they are present, Axone.jar displays them.

When the software reads an MP3 file to display the current tag, it does a summary check of the audio data. It gives you the classic information on bitrate, sampling frequency, duration, etc.; but also if it finds excess or erroneous data. Excess data can be a sign of corrupted audio data, or of data intentionally hidden if the file was purchased on a merchant site (or if you did P2P). At this level, it is important to understand that the audio decoder is robust in the sense that data that is incomprehensible to it is simply skipped. It is therefore very easy to hide data between audio data, without risking disturbing MP3 players.
