Free lame mp3 codec software for linux

LAME is short from LAME Aint an MP3 Encoder and is a research project for learning about and improving MP3 encoding technology. LAME includes an MP3 encoding library, simple frontend application, a much-improved psycho-acoustic model (GPSYCHO), and a graphical frame analyzer (MP3x).
Please note that any commercial use (including distributing the LAME encoding engine in a free encoder) may require a patent license from Thomson Multimedia.
Main features:
- Many improvements in quality in speed over ISO reference software. See history.
- MPEG1,2 and 2.5 layer III encoding.
- CBR (constant bitrate) and two types of variable bitrate, VBR and ABR.
- Encoding engine can be compiled as a shared library (Linux/UNIX), DLL or ACM codec (Windows)
- free format encoding and decoding
- GPSYCHO: a GPLd psycho acoustic and noise shaping model.
- Powerfull and easy to use presets
- Quality is comparable to FhG encoding engines and substantially better than most other encoders.
- Fast! Encodes faster than real time on a PII 266 at highest quality mode.
- MP3x: a GTK/X-Window MP3 frame analyzer for both .mp3 and unencoded audio files.

- out_lame (Windows) Winamp output plug-in. Create MP3 files directly from Winamp!
- RazorLame (Windows) The RazorBlade front end now supports LAME.
- winLAME (Windows) The only *nice* windows UI for LAME, according to the author :-)

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.

Apache::MP3::Sorted is a Perl module to generate sorted streamable directories of MP3 files.

SYNOPSIS

# httpd.conf or srm.conf
AddType audio/mpeg mp3 MP3

# httpd.conf or access.conf
< Location /songs >
SetHandler perl-script
PerlHandler Apache::MP3::Sorted
PerlSetVar SortFields Album,Title,-Duration
PerlSetVar Fields Title,Artist,Album,Duration
< /Location >

Apache::MP3::Sorted subclasses Apache::MP3 to allow for sorting of MP3 listings by various criteria. See Apache::MP3 for details on installing and using.

BladeEnc is a freeware MP3 encoder. It is based on the same ISO compression routines as mpegEnc, so you can expect roughly the same, or better, quality . The main difference is the appearance and speed.
BladeEnc doesnt have a nice, user-friendly interface like mpegEnc, but it is more than three times faster, and it works with several popular front-end graphical user interfaces.
BladeEncs output quality is one of those rare subjects that completely divides the world in two parts. Either you love it or you hate it, there never seems to be an opinion inbetween. Different audiophiles and mp3 experts tends to come to completely different conclusions depending on their methods and testsamples.
The reason for this is of course that BladeEnc is a very different mp3 encoder (compared to Fraunhofer, LAME etc) with a very unique approach to mp3 encoding.
In order to compress sound to an mp3 file, you need to make certain sacrifices in quality. Taking into account how we percieve sound, the mp3 encoder tries to remove the details that it believes us to be least likely to notice. How much that needs to be removed depends on the bitrate and the encoder often has the choice of doing different kinds of sacrifices.
It can remove low volume tones that are "shadowed" by high volume tones of similar frequencies, remove the high frequency part of the sound spectrum, cut down the stereo effect (so called joint stereo) and simply decrease the samplerate. What approach is the best depends on a lot of things, like the style of music and the selected bitrate.
Main features:
- Sourcecode available under the LGPL-license!
- Stereo or Mono output. Can downmix to Mono on the fly.
- Supports the following bitrates: 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256 and 320 kBit/s. However, for bitrates lower than 128 kBit we seriously recommend you to use another encoder.
- Flags like Private, Original and Copyright can be set.
- Input samples can be in either 32, 44.1 or 48 kHz.
- Both 8 and 16-bit samples are supported.
- Working CRC checksum generation (since 0.80). The ISO reference code had broken CRC calculations, which has been inherited into every ISO based encoder that havent added a fix for it.
- Can be plugged directly into many popular 3rd party products, giving them integrated mp3 encoding abilities.
- Encodes chunks of data from memory to memory, no need to use files or pipes.
- Can be compiled for nearly any operating system still in use.
- Commandline based, makes it easy to include BladeEnc into BAT files and shell scripts.
- Only mp3 encoder that supports gapless encoding.
- Reads standard uncompressed WAV- and AIFF-files as well as well as RAW PCM-data.
- Batch encoding. Can encode any number of samples in a row.
- Wildcards supported. You can for example encode all WAV-files in a directory by typing *.WAV".
- Input samples can be automatically deleted after encoding.
- Large selection of graphical frontends available.
- Task priority can be set from the commandline and is by default set to LOWEST so that you still can use your computer effectively while encoding (Windows & OS/2 only).
- Full support for pipes and redirection (stdin and stdout).
- Textbased configuration file where you can change default settings.

Apache::MP3::Skin is a subclass of Apache::MP3::Playlist with the ability to "skin" the output using HTML::Template.

SYNOPSIS

# httpd.conf or srm.conf
AddType audio/mpeg .mp3 .MP3

# httpd.conf or access.conf
< Location /songs >
SetHandler perl-script
PerlHandler Apache::MP3::Skin
PerlSetVar HomePath /songs # optional
PerlSetVar DefaultSkin default.tmpl # required

# Without DefaultSkin being set to a valid file
# Apache::MP3::Skin will be the same as Apache::MP3
< /Location >

Apache::MP3::Skin subclasses Apache::MP3::Playlist enabling the use of skin files which are html files with special tags enabled by HTML::Template. See Apache::MP3 for details on installing and using.

cdmp3 uses cdparanoia or cdda2wav to extract single tracks or even a whole CD and converts them on-the-fly into MP3 or Ogg Vorbis files. Using the CDDB database it is possible to include information like the artists name or the tracks title into the file name or as meta tags into the file content.
cdmp3 consists of a single perl script. Copy it to where ever you want it to reside, /usr/local/bin might be a good place. You might also want to create a symlink, named "cdogg", which points to cdmp3, so that by running cdogg, you preset cdmp3 to creating Ogg Vorbis files instead of MP3.
Additionally you will need the next packages, but this depends on the command line arguments you give to cdmp3:
cdparanoia http://www.xiph.org/paranoia/
cdda2wav ftp://ftp.berlios.de/pub/cdrecord/ (package cdrtools)
lame http://www.mp3dev.org/
oggenc http://www.vorbis.com (package vorbis-tools)
CDDB_get perl module http://armin.emx.at/cddb/
bfr http://www.glines.org:8000/software/buffer.html
If you are running Debian, all these packages are provided by the Debian
project itself or by third parties.
Enhancements:
- converted cdmp3 to perl
- merged get_cddb into cdmp3 main script
- added "--print-cddb": fetch and print cddb entry, exit
- added %y and %g filename format patterns
- support two-digit track numbers (%0n and %0u)
- patterns are really handled printf(1)-like now
- more flexible command line arguments

Template::Plugin::MP3::Tag is a Perl interface to the MP3::Tag Module.

SYNOPSIS

[% USE tag = MP3("path_to_mp3_file") %]

[% tag.title %]
[% tag.album %]

# perldoc MP3::Tag for more ideas

Template::Plugin::MP3::Tag provides a simple wrapper for using MP3::Tag in object oriented mode; see MP3::Tag for more details.

Although Template::Plugin::MP3 can fetch MP3 files, but it Supports only ID3v1. When you have to fetch MP3 files ID3v2, I recommend you to use this module.
