Carat is a lightweight, automated GUI utility designed to accept Dolby Atmos music releases in practically any format, locate the primary title in the release, retrieve metadata and cover art from the internet, and incorporate the release directly into your digital music library in a single click.
From the moment a new Blu-ray arrives in your mailbox, Carat handles the entire pipeline—extraction, processing, metadata acquisition, and cover art—with zero friction. If your source files are already on your SSD, Carat will process an entire release in a minute or two (depending on the speed of your computer). If you are starting from a physical disc, the time is limited by the read speed of your optical drive (expect five to ten minutes).

A high-performance CLI toolkit for music collectors who manage their own libraries. Lattice provides a suite of tools for library visualization, integrity verification, cover art extraction, and metadata auditing — all from a single, zero-dependency script.
Modern music players often hide your library behind proprietary databases. Lattice is built for collectors who treat the filesystem as the source of truth. It reads tags directly via mutagen, ensuring your library is portable and player-agnostic.
| Mode | Flag | Description |
|---|---|---|
| Library Tree | --library | Generate a formatted ASCII/Unicode tree of your entire collection. |
| AI Library | --ai-library | Token-efficient export designed for LLM recommendation prompts. |
| Genre Wings | --all-wings | Generate separate library catalogs segmented by genre. |
| Integrity Checks | --testFLAC | Parallel verification of FLAC/MP3/Opus/WAV integrity via FFmpeg. |
| Art Extraction | --extractArt | Extract embedded covers with format-priority ranking (FLAC > Opus). |
| Tag Audit | --auditTags | Identify and report files with missing or inconsistent metadata. |

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:
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 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.
