Perl Module MP3::Tag

How to edit MP3 meta tags in Perl with the MP3::Tag Perl module.

Perl can be a great way to process your ever growing collection of MP3's - you can use it to organize them, queue them to play, or using the MP3::Tag, you can read and even edit the ID3 tags to clean them up.

First, like all non-standard Perl modules, you will need to install MP3::Tag from CPAN, and then you can include it at the top of your Perl programs with the use statement:

use MP3::Tag;

Then you can load up an MP3 file and grab the file information with some pre-made functions like autoinfo:

$mp3 = MP3::Tag->new($filename);
($title, $track, $artist, $album, $comment, $year, $genre) = $mp3->autoinfo();

Or you can use the get_tags function to grab the fill ID3 tags and read them:

$mp3->get_tags;
if (exists $mp3->{ID3v1}) {
print $mp3->{ID3v1};
}
if (exists $mp3->{ID3v2}) {
print $mp3->{ID3v2};
}

For ID3v1 and ID3v2 tags, you can even change or delete the values, giving you a powerful processing tool if you need to edit large batches of MP3 or just want to make sure your tags are nice and clean. Module Links:
