Free mp3 editor software for linux

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.

Dynamic MP3 Lister was a project I started a long time ago to create dynamic lists of MP3s quickly and easily.

Features MP3 Information extraction for things like bitrate, channels, playtime and more.

Please note that this script is discontinued, and is only shown here now as an example of my work.

An MP3 LEnder is a simple MP3 server written in C.
AMPLE is short for "A MP3 LEnder" (interesting name just to make a good abbreviation?)
I wrote AMPLE one summer when I was coding for a company and got fed up with having to FTP over all my MP3 files from my home server to the computer at work just to listen to them. And the other "MP3 servers" I could find didnt fit my needs for one of the following reasons:
Depended on libfoo, libbar, python, perl, php3, Apache, libssl, etc, etc, etc...I just wanted to listen to the files
Had a lot of features for "DJ:ing" etc that I really didnt need
Well....it was fun to write too :)
So whats good with AMPLE?
Small, standalone (written in C using no external libraries)
Portable (I think), I often try to compile it on the SourceForge compile farms
Allows you to listen to your own MP3s away from home, nothing more, nothing less
This is beginning to sound like marketing cr*p so Ill just stop right there, check out the links on the left for more info.
Enhancements:
- Make ID3v2 code understand versions 2.2.0 -> 2.4.0 (all currently existing versions)
- Reformat HTML output somewhat
- Fix search-and-replace error in libwrap code
- Made servername a config option
- Renamed -r to -n (NON-recursive)
- Changed the DEF_LOGFILE (it pointed to ample.conf instead of ample.log)
- Much work on autoconf stuff, should work much better now
- Some more testing on other architectures (Ive compiled it on everything from Tru64 to Linux to *BSD)

This module enables to listen to mp3-streams according to certain security policies (enabled user). The mp3s do not have to be in the web-servers document root.
Main features:
- XHTML compliant.
- Admin interface allows you to change position, visibility and title of the stream playlist Box.
- You dont have to fiddle around with config files. Interface is provided to configure the paths etc., user access and reset the access counter.
- Dynamic directory parsing for mp3-files
- mp3-file names are not held in a database as the File/Directory names are used to create the displayed Songs, album titles etc. as mp3 tags extraction capabilities are not included in php by default.
- Artist, Album, mp3-file browsable
- Playlist handling capabilities with playlist editor
- Demo mode for guests possible, e.g. streaming not enabled.
- Clicking on a Song will send a mpeg-url type information to the mp3-player application such as winamp or xmms. (Tested under linux with xmms only).
Version restrictions:
- The software only searches through 2 Directory structures. It is meant to go through: $mp3dir/Artist-Name/Album-Name/mp3-files.mp3 It however detects files in the Artist-Directory and shows these accordingly. As I didnt use this function, I dont know what it looks like though.

MP3 Report Generator is a customizable program to scan a list of (sub)directories, creating a report from an HTML template.

Also calculates various statistics and each songs playing time. Supports ID3 and ID3v2 tags.

All options can be configured through the command line, see mp3report.pl --help for more info. You may also want to modify the hard coded defaults at the top of the program file.

Usage: mp3report.pl [options] [directory...]
--help shows this help screen
--printmode uses a smaller font for printing
--title=TITLE sets the title used in the report
--outfile=OUTFILE file to write report to, - for STDOUT
--template=FILE file to use as report template
--stdgenres use standard genres instead of winamp genres
--id3v2 enable id3v2 support (experimental)
directory... dirs to scan (subdirs included)

Installation:

You should be able to run mp3report.pl directly after decompressing it:

tar xfzv mp3report-1.0.0.tar.gz
cd mp3report-1.0.0
./mp3report.pl --help

If your perl interpreter isnt in /usr/bin/perl, youll need to change the first line of mp3report.pl

xmpgedit project is an MP3 editor for VBR and CBR encoded files.
xmpgedit is an MPEG 1 layer 1/2/3 (MP3), MPEG 2, and MPEG 2.5 audio file editor that is capable of processing both Constant Bit Rate (CBR) and Variable Bit Rate (VBR) encoded files.
xmpgedit can cut an input MPEG file into one or more output files, as well as join one or more input MPEG files into a single output file. Since no decoding or encoding occurs during editing, there is no audio quality loss when editing with xmpgedit.
Enhancements:
- This release fixes an occasional crash in xmpgedit when adjusting the volume after playback has stopped.
- xmpgedit playto start time is fixed, which would play beyond the specified edit time in some circumstances.
- Added the command "Copy start time" to the xmpgedit edit menu.

MP3::Info is a Perl module that can manipulate / fetch info from MP3 audio files.

SYNOPSIS

#!perl -w
use MP3::Info;
my $file = Pearls_Before_Swine.mp3;
set_mp3tag($file, Pearls Before Swine, q"77s",
Sticks and Stones, 1990,
q"(c) 1990 77s LTD.", rock & roll);

my $tag = get_mp3tag($file) or die "No TAG info";
$tag->{GENRE} = rock;
set_mp3tag($file, $tag);

my $info = get_mp3info($file);
printf "$file length is %d:%dn", $info->{MM}, $info->{SS};
my $mp3 = new MP3::Info $file;
$mp3->title(Perls Before Swine);
printf "$file length is %s, title is %sn",
$mp3->time, $mp3->title;

$mp3 = MP3::Info->new(FILE)

OOP interface to the rest of the module. The same keys available via get_mp3info and get_mp3tag are available via the returned object (using upper case or lower case; but note that all-caps "VERSION" will return the module version, not the MP3 version).

Passing a value to one of the methods will set the value for that tag in the MP3 file, if applicable.

use_mp3_utf8([STATUS])

Tells MP3::Info to (or not) return TAG info in UTF-8. TRUE is 1, FALSE is 0. Default is TRUE, if available.

Will only be able to turn it on if Encode is available. ID3v2 tags will be converted to UTF-8 according to the encoding specified in each tag; ID3v1 tags will be assumed Latin-1 and converted to UTF-8.

Function returns status (TRUE/FALSE). If no argument is supplied, or an unaccepted argument is supplied, function merely returns status.

This function is not exported by default, but may be exported with the :utf8 or :all export tag.

use_winamp_genres()

Puts WinAmp genres into @mp3_genres and %mp3_genres (adds 68 additional genres to the default list of 80). This is a separate function because these are non-standard genres, but they are included because they are widely used.

You can import the data structures with one of:
use MP3::Info qw(:genres);
use MP3::Info qw(:DEFAULT :genres);
use MP3::Info qw(:all);

remove_mp3tag (FILE [, VERSION, BUFFER])

Can remove ID3v1 or ID3v2 tags. VERSION should be 1 for ID3v1 (the default), 2 for ID3v2, and ALL for both.

For ID3v1, removes last 128 bytes from file if those last 128 bytes begin with the text TAG. File will be 128 bytes shorter.

For ID3v2, removes ID3v2 tag. Because an ID3v2 tag is at the beginning of the file, we rewrite the file after removing the tag data. The buffer for rewriting the file is 4MB. BUFFER (in bytes) ca change the buffer size.

Returns the number of bytes removed, or -1 if no tag removed, or undef if there is an error.

set_mp3tag (FILE, TITLE, ARTIST, ALBUM, YEAR, COMMENT, GENRE [, TRACKNUM])

set_mp3tag (FILE, $HASHREF)

Adds/changes tag information in an MP3 audio file. Will clobber any existing information in file.

Fields are TITLE, ARTIST, ALBUM, YEAR, COMMENT, GENRE. All fields have a 30-byte limit, except for YEAR, which has a four-byte limit, and GENRE, which is one byte in the file. The GENRE passed in the function is a case-insensitive text string representing a genre found in @mp3_genres.

Will accept either a list of values, or a hashref of the type returned by get_mp3tag.
If TRACKNUM is present (for ID3v1.1), then the COMMENT field can only be 28 bytes.

ID3v2 support may come eventually. Note that if you set a tag on a file with ID3v2, the set tag will be for ID3v1[.1] only, and if you call get_mp3tag on the file, it will show you the (unchanged) ID3v2 tags, unless you specify ID3v1.

get_mp3tag (FILE [, VERSION, RAW_V2])

Returns hash reference containing tag information in MP3 file. The keys returned are the same as those supplied for set_mp3tag, except in the case of RAW_V2 being set.
If VERSION is 1, the information is taken from the ID3v1 tag (if present). If VERSION is 2, the information is taken from the ID3v2 tag (if present). If VERSION is not supplied, or is false, the ID3v1 tag is read if present, and then, if present, the ID3v2 tag information will override any existing ID3v1 tag info.

If RAW_V2 is 1, the raw ID3v2 tag data is returned, without any manipulation of text encoding. The key name is the same as the frame ID (ID to name mappings are in the global %v2_tag_names).

If RAW_V2 is 2, the ID3v2 tag data is returned, manipulating for Unicode if necessary, etc. It also takes multiple values for a given key (such as comments) and puts them in an arrayref.

If the ID3v2 version is older than ID3v2.2.0 or newer than ID3v2.4.0, it will not be read.

Strings returned will be in Latin-1, unless UTF-8 is specified (use_mp3_utf8), (unless RAW_V2 is 1).

Also returns a TAGVERSION key, containing the ID3 version used for the returned data (if TAGVERSION argument is 0, may contain two versions).
get_mp3info (FILE)

Returns hash reference containing file information for MP3 file. This data cannot be changed. Returned data:

VERSION MPEG audio version (1, 2, 2.5)
LAYER MPEG layer description (1, 2, 3)
STEREO boolean for audio is in stereo

VBR boolean for variable bitrate
BITRATE bitrate in kbps (average for VBR files)
FREQUENCY frequency in kHz
SIZE bytes in audio stream
OFFSET bytes offset that stream begins

SECS total seconds
MM minutes
SS leftover seconds
MS leftover milliseconds
TIME time in MM:SS

COPYRIGHT boolean for audio is copyrighted
PADDING boolean for MP3 frames are padded
MODE channel mode (0 = stereo, 1 = joint stereo,
2 = dual channel, 3 = single channel)
FRAMES approximate number of frames
FRAME_LENGTH approximate length of a frame
VBR_SCALE VBR scale from VBR header
On error, returns nothing and sets $@.
