## What it is
A pure Java library for reading MP3 files and reading, writing, adding, and removing ID3 tags (ID3v1 and ID3v2.2 through ID3v2.4). It supports low-level MPEG frame data, VBR files, embedded album art, and unicode, and is available via Maven Central.

## Use cases
- read id3 tags from mp3 files in java
- rename mp3 files based on their id3 tags
- add or extract album art images from mp3 files
- retag mp3 files programmatically
- get mp3 bitrate, sample rate, and duration
- handle vbr mp3 files correctly
- remove or add id3v1 and id3v2 tags

## When to choose
- you need a pure Java, dependency-light MP3/ID3 tag library on the JVM
- you need support for ID3v1 and ID3v2.2 through ID3v2.4 including embedded images
- you need accurate VBR handling by reading actual MPEG frames

## When to avoid
- you need actively maintained software - the repo is no longer maintained and forks may be better
- you need to write ID3v2.2 tags (read-only support)
- you need to process audio formats other than MP3

## Facets
- artifact type: library
- maturity: maintenance
- function: parser, serialization, developer-tools
- domain: files, developer-tools
- platform: jvm, cross-platform
- tags: mp3, id3-tags, audio-metadata, java-library, audio
