Free mp3 tag database software for linux

MP3DB2 is a collection of bash scripts for keeping track of large MP3 collections. It will retrieve song information from the filenames and ID3 tags of a directory or CD of MP3s and store them in a local database.
This program is a complete rewrite of my MP3 database version 1. Version 1 only stored the data that was present in the filenames while version 2 actually retrieves information from the ID3 tags of each MP3.
Please note that as of this version the database format is NOT considered carved in stone. I have already added a few fields mid-development and this will continue for a while if I think the format can be made better. See the changelog for a list of changes to the database format since V2.0.
Enhancements:
- mp3dupe: now just displays the name of the directory we are checking not the full path in the host filesystem.

pytags is a Python library capable of reading and writing MP3, FLAC and OGG file tags.

Being tired of having to use a different API calls for the main 3 media files in my library I created this library class. It utilizes pyid3lib, python-vorbis and python-flac as backends. None are required, however, it is up the program implementing the class to decide which backends are needed. Note this library has not been widely tested yet. It is just being subject to release early and release often. That being said I have not suffered any corruption during any part of the development besides perhaps the loss of tag data.

Given that the Vorbis and FLAC tags are wildly different from ID3 some liberties have been taken on my part. While ID3 is limited to one field of each data Vorbis/FLAC can have as many as you want. This library handles that by only returning the first match on a get query. (Perhaps in the future they will all be returned) On a set query the new item will just be added on to the others. If a set then get occurs the last one set will be returned. Feel free to contact me tkorody you.know.what.to.do socal.rr.com with any questions or comments you may have.

Example of the API:

import pytags, os

print pytags.tags.get_Supported_Formats()
try:
media_file = pytags.tags(a_cool_song.flac)
except FileNotSupported:
print This file doesnt seem to be supported
os.exit(-1)

# Note the str() is used because None type object can get returned!
print Artist is + str(media_file.get_Artist())
print Album is + str(media_file.get_Album())
print Title is + str(media_file.get_Title())
print Track Total is + str(media_file.get_TrackTotal())
print Track Number is + str(media_file.get_TrackNumber())
print Genre is + str(media_file.get_Genre())
print Disc Number is + str(media_file.get_DiscNumber())
print Comment is + str(media_file.get_Comment())
print Date is + str(media_file.get_Date())

print Now Settings Tags!

MP3::Tag::ID3v2-Data can get_frame() data format and supported frames.

SYNOPSIS

$mp3 = MP3::Tag->new($filename);
$mp3->get_tags();
$id3v2 = $mp3->{ID3v2} if exists $mp3->{id3v2};

($info, $long) = $id3v2->get_frame($id); # or

($info, $long) = $id3v2->get_frame($id, raw);

This document describes how to use the results of the get_frame function of MP3::Tag::ID3v2, thus the data format of frames retrieved with MP3::Tag::ID3v2::get_frame().

It contains also a list of all supported ID3v2-Frames.

get_frame()
($info, $long) = $id3v2->get_frame($id); # or

($info, $long) = $id3v2->get_frame($id, raw);

$id has to be a name of a frame like "APIC". See also L .

The names of all frames found in a tag can be retrieved with the L function.

MP3::Tag::LastResort is a Perl module for using other fields to fill autoinfo fields.

SYNOPSIS

my $mp3extra = MP3::Tag::LastResort::new_with_parent($filename, $parent);
$comment = $mp3inf->comment();

see MP3::Tag

MP3::Tag::LastResort is designed to be called from the MP3::Tag module.
It uses the artist_collection() as comment() if comment() is not otherwise defined.

PGID3 is an ID3v1 and v2 tag editor for manipulating the information on files such as MP3s. PGID3 Tag Editor project is written in PHP and uses PHP-GTK, so it can take advantage of the GTK+ Toolkit for rendering a GUI.

The program itself is broken into three parts, a PHP Function Library called Pid Three (Pid3), a PHP CLI interface (PCLID3), and the GTK+ GUI itself. All three parts come together ready to go, so do not go freaking about uber amounts of dependencies to fill. All together they create the PGID3 Tag Editor.

"But Bob," you might say, "PHP is for the web!" Sure it is, but you should then check out the link below for the PHP Command Line Interface. That document describes using PHP to develop shell and desktop applications. Why PHP? Because I like to abuse it, that is a little hobby of mine.

Simply, PGID3 is an ID3 tag editor for MP3 files. The ID3 tags are what tell your media player the information about the tune such as title, album, etc. You can get by with slack tags if you just use a player like XMMS or Winamp, but if you have a portable like an iPod or some kind of database for the files, then correct and neat tags are a must. PGID3 can handle both the v1 and v2 of ID3 tags.

As for the program itself, it is the combonation of three seperate pieces that together work to create a user friendly envrionment to manipulate your ID3 tags. The base of it all is the Pid Three Function library, which is a fully custom set of functions for the reading and writing of ID3 tags. Since these are seperate from the application itself, the actual dirty work of messing with the data can be easily updated as well as easily included into other projects.

The second part of PGID3 is the Command Line Interface that I have lovingly called PCLID3. Using this you can manipulate your tags from the command line without using any type of graphical front end. By not having this built into the GUI, the opportunity is left open to build alternate GUIs, or even just not use any at all.

The third and final piece is the PHP-GTK GUI. This is the actual PGID3 component, though all of the parts together form a complete package under the PGID3 name. I designed this GUI to be light, compact, and solve as many problems in one spot as possible. As a bonus feature, PGID3 has built in intergration with QueryXMMS which is a command line utility for Linux that can ask XMMS what is currently playing so PGID3 can open it. This speeds up editing of playlists considerably.

Enough acronymns, what about features? Well, it is an ID3 editor so the features I would expect to find in one is what it has. It has the ability to read, write, and strip ID3v1 and ID3v2 tags from files. You can open a file from anywhere in the filesystem with a dialog, or using the above mentioned QueryXMMS integration you can zap right to whatever XMMS is playing.

If you leave the comment field blank when you write a tag, it fills it in automaticly with "Tagged by PGID3" which might be an easily disabled in future releases - depends if I get any feedback on that. It also automaticly removes excess whitespace on the end of tags which if I recall correctly happens because Winamp pads with spaces instead of nuls. Anyway it cleans that for you. Stripping a tag automaticly unchecks the related checkbox for writing it back, and the boxes are dynamicly checked as you load a file depending if it already has a v1 or v2 tag.

There are also a few keyboard shortcuts. F1 toggles the Write ID3v1 checkbox, and F2 toggles the Write ID3v2 one. F9 opens the currently playing file in XMMS, and naturally Enter writes tags.

PHP Tag Engine project is a library that allows you to easily add tagging functionality to a PHP application.
Main features:
- PHP Tag Engine has a full AJAX front-end for tagging, as well as methods for programatically adding tags in your code. The front-end tagging interface even has auto-complete functionality using the excellent Yahoo! Auto-Complete library.
- A built-in cache to reduce database queries.
- The PHP Tag Engine code is fully documented in PHP Doc format, and PHP Doc generated documentation is available for download.
- Fully internationalized including Javascript strings. English localization included.

MPEG::ID3v2Tag is a Perl module that parses and creates ID3v2 Tags for MPEG audio files.

SYNOPSIS

use MPEG::ID3v2Tag ;
use IO::File ;

# create a tag
$tag = MPEG::ID3v2Tag->new() ;
$tag->add_frame("TIT2", "Happy Little Song") ; # one step
$frame = MPEG::ID3Frame::TALB->new("Happy little album") ;
$tag->add_frame($frame) ; # two steps
$tag->add_frame("WCOM", "http://www.mp3.com") ;
$tag->add_frame("APIC", -picture_type => 0, -file => "happy_little_song.gif");
.....
$tag->set_padding_size(256) ;
print OUTFILE $tag->as_string() ;

# read a tag from a file and dump out some data.
$fh = IO::File->new(" binmode $fh;
$tag = MPEG::ID3v2Tag->parse($fh) ;
foreach $frame ($tag->frames()) {
print $frame->frameid(), "n" ; # prints TALB, TIT2, WCOM, etc.
if ($frame->flag_read_only()) {
print " read onlyn" ;
}
if ($frame->fully_parsed() && $frame->frameid =~ /^T.../) {
print " frame text is ", $frame->text(), "n" ;
}
if ($frame->fully_parsed() && $frame->frameid =~ /^W.../) {
print " url is ", $frame->url(), "n" ;
}
}

MPEG::ID3v2Tag is a class capable of parsing and creating ID3v2 revision 3 tags. While not all frames are fully supported, its easy to add support for more.
The object doesnt (currently) support modification of .mp3 files; the caller has to handle the mechanics of prepending the tag to the file.
