This is a lightweight and easy to use library to create and add ID3 metadata tags to MP3-files. It only concerns itself with ID3 version 3.2.0 and only handles the most common types of information, but creating a tag and adding it to a file is much easier than with the other solutions that I have used.
It also has one fairly esoteric feature that is interesting from a algorithmical standpoint but that I doubt that anyone but me will ever use, and that is the ability to create CRC32 neutral ID3-tags. That means that you can add such a tag to any MP3-file and the CRC32 sum of the resulting MP3 file with the tag is the same as the file without the tag. A handy feature if you have a system that generates dynamic metadata information for pre-generated MP3-files and use the combination of dynamic metadata and static MP3 files to create large dynamic zip archives and don't want to re-calculate all the checksums. I happened to have built such a system that can be used at http://voxbiblia.com/ but it would surprise me if anyone else has use for that feature, ever.
- Lightweight. The binary jar is less than 16k at the moment, and has no external dependencies except JDK 1.5. When developing, I use JUnit for automated testing but that is not needed when using or compiling the library.
- Easy to use and develop. Clean and maintainable code.
- Handles international characters outside of the US-ASCII range correctly, using full unicode when needed.
- Free software. Released under the GPL 3.0 license, this software can be used, modified and redistributed by anyone respecting the terms of the license. If you need other licensing options, please contact me.
The basic use case looks like this
ID3Tag tag = new ID3Tag();
tag.setArtist("Tingsek");
tag.setAlbum("World Of It's Own");
tag.setName("So Real");
ID3Tool.writeToFile(new File("so_real.mp3"), tag);
For further details, please see the JavaDoc documentation.
