Free mp3 software for linux

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.

Canzoniere is an Mp3 mood classifier.

Canzoniere is an mp3 classification tool, which allows users to classify their songs using personal criteria such as artist score, song score and moods (i.e. romantic, relax, party, etc.). Users can then select their mood and play songs that match.

AutoRip is a non-interactive, non-intrusive mp3 rip-and-encode front end. Simply drop your CD into your CD-ROM drive, wait for your CD to eject, wash, rinse, and repeat.

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

Mp3 renamer 2006 by MiKe is a shell script for Linux. MP3 renamer goes by the Unix name of rename-mp3. It looks at MP3 files in a Directory and, using id3v2, will rename all the mp3 files in a nice format according to the id3 tags rename-mp3 will look at both v1 and v2 id3 tags, and will make the output file in a Title-Album-Artist.mp3 format.
It saves time, and not only will it read the id3 tags, but in the event that the MP3 file has no id3 tags, you will be given 4 options
1)abort 2)skip 3)rename 4)write id3 tags, and you are asked what you would like the id3 tag artist, track name and album to be.
This is great if you want the track to be easy to view and yet you still like having a library of music that is all tagged nicely!
Enhancements:
- New stuff: The INSTALLER now works, whereas before it wouldnt copy...

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)

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 $@.
