NAME

MP3::ID3Lib - ID3v1/ID3v2 Tagging of MP3 files

SYNOPSIS

  use MP3::ID3Lib;
  my $id3 = MP3::ID3Lib->new($filename);

  foreach my $frame (@{$id3->frames}) {
    my $code = $frame->code;
    my $description = $frame->description;
    my $value = $frame->value;
    $frame->set("Orange") if $code eq 'TPE1';
    print "$description: $value\n";
  }

  $id3->add_frame("TIT2", "Title goes here");
  $id3->commit;

DESCRIPTION

This module allows you to edit and add ID3 tags in MP3 files.

ID3 tags are small pieces of information stored inside the MP3 file. They can contain bits of metadata about the MP3, such as album name, song name, artist, original artist, genre, composer, year of release, additional comment fields, and many more.

This module is an interface to the high-quality id3lib library available from http://id3lib.sourceforge.net/, which must be installed. At the moment, it is a bit of a low-level interface and some knowledge of ID3v2 is useful. You should know about tag names and tag usage. The best website for this is http://www.id3.org/.

However, to get started, a few frame names you may find useful are:

  • TIT2: Title/songname/content description

  • TPE1: Lead performer(s)/Soloist(s) (artist)

  • TALB: Album/Movie/Show title

  • TRCK: Track number/Position in set

  • TYER: Year

  • TCON: Content type ('genre')

  • COMM: Comments

Please note that id3v1 has length restrictions on these fields.

BUGS

The API could be better and there are a couple of small memory leaks.

This module currently only returns the first 100 ASCII characters of a text tag.

This module is currently unable to read or write ID3 v2.4.0 tags.

THANKS

Thanks go to Chris Nandor for letting me use his test MP3s and to Paul Mison for the idea.
