Free vbr mp3 software for linux

Sort MP3 is a script was made to help in organizing MP3s. If you have one directory with allot of mp3s and the names are not very readable you can run this script against them. It will read the id tag of a mp3 and rename the file to the title of the song but with _ instead of spaces. It can also create a directory structure from the id tag if the -c option is used. The structure will be put in the same directory the mp3s are in. It will be something like: "/BANDNAME/CDTITLE/SONG.mp3"

Usage: sort_mp3.pl [options]
Options should be separated by a space and my be
in any order.

-c Create a directory structure from the mp3 tag.
It is made inside the directory holding the un-named mp3s.
If not set the files will just be renamed.
Example: "/BANDNAME/CDTITLE/SONG.mp3"

-d= Path to the directory where mp3s can be found.
There should be no / at the end and no spaces.
Example: "-d=/unsorted_mp3s"

Bundle::MP3 is a bundle to install all MP3-related modules.

SYNOPSIS

perl -MCPAN -e install Bundle::MP3

CONTENTS

MP3::Info - For MP3::Info by Chris Sandor

Digest::MD5 - Used by MP3::Napster

MP3::Napster - For MP3::Napster by Lincoln Stein

Bundle::Xmms - For Xmms by Doug MacEachern

This bundle installs a bunch of modules related to sharing and playing MP3 files, including MP3::Info by Chris Sandor, MP3::Napster, by Lincoln Stein, and the Xmms bundle by Doug MacEachern.

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.

cutmp3 is a small and fast command line MP3 editor. cutmp3 lets you select sections of an MP3 interactively or via a timetable and save them to separate files without quality loss.
It uses mpg123 for playback and works with VBR files and even with files bigger than 2GB.
Other features are configurable silence seeking and ID3 tag seeking, which are useful for concatenated mp3s.
Playback is realized via mpg123, so be sure to have it installed or at least have a symlink to your favorite mp3 playing program.
I recommend a symlink to mpg321 which works better!
You can mark beginning and end of a segment with a and b and save the segment with s.
Using a timetable or direct times with VBR files delivers exact(!) results at the cost of slightly lower speed. cutmp3 even works with files bigger than 2 GB!
If you want a working graphical software you can try mp3directcut,
which runs fairly well in WINE after I asked the author about a WINEd version.
Installation:
make (you will need readline-devel or similar!)
install it to /usr/bin with
make install
Enhancements:
- A small fix for timetable cutting with negative values has been made.
- Another option for silence seeking has been added.
- The documentation has been updated.

PyMP3Cut is a Python command line tool designed to cut huge (> 100MB) MP3 files at high speed without requiring the extra disk space and processing time usually needed by visual audio editing tools, which convert the MP3 format to more easily manageable formats like WAV before doing anything.
It cuts and reads simultaneously according to the autodetected MP3 frame rate and a timeline passed as a command line argument. It doesnt currently deal with Variable Bit Rate (VBR) MP3 files, though.
Main features:
- PyMP3Cut is a Python command line tool designed to cut very huge MP3 files at a blazzingly fast rate without requiring the extra disk space and processing time usually needed by Audacity or other similar visual audio editing tools, which convert the MP3 format to more easily manageable formats like WAV before doing anything. The WAV conversion usually requires 10 times more disk space !
- PyMP3Cut doesnt convert anything : it reads and cuts simultaneously, according to the autodetected audio frame rate and a timeline passed as a command line argument. You can think of PyMP3Cut as being some sort of very careful chainsaw ;-) Since theres no back and forth MP3 conversion, theres no quality loss either !
- PyMP3Cut was designed to slice high quality MP3 recordings of day-long congresses into smaller per-speaker MP3 files. It only needs the exact same amount of disk space as the original file to slice, even less if you plan to skip some parts, which PyMP3Cut can do automatically if you use a specially formatted *SKIP* entry in your timeline. It was successfully used many times against several hundredths megabytes MP3 files.
Enhancements:
- Bill Eldridge added the --segment command line option.

web mp3 player for xmms is a simple Web MP3 player based on XMMS and XMMS-Shell.

The project is useful if you have a Linux server attached to your stereo/home theater and you want to play MP3s easily via a Web interface.

A little playlist support is included. Important note: it is totally insecure, and should only by used in a limited environment.

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 $@.
