Free lame mp3 encoder software for linux

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.

mpTcv is a GUI for LAME to convert MP3 to other bit rates. mpTcv lets the user choose a directory to recode to another bit rate.

This is useful for cramming more data onto USB sticks, MP3 players, etc.

POE::Component::Enc::Mp3 is a mp3 encoder wrapper.

SYNOPSIS

use POE qw(Component::Enc::Mp3);

$mp3 = POE::Component::Enc::Mp3->new($bitrate => 160);

$mp3->enc("/tmp/tst.wav");

POE::Kernel->run();

This POE component encodes raw audio files into mp3 format. It is merely a wrapper for the notlame program.

METHODS

The module provides an object oriented interface as follows:

new

Used to initialise the system and create a module instance. The following parameters are available:

alias

Indicates the name of a session to which module callbacks are posted. Default: main.

bitrate

Should be self-evident. If left unspecified, defaults to 160.

enc < file-name > [del-orig]

Encodes the given file, naming it with a .mp3 extension. An optional true value for the second parameter indicates that the original file should be deleted.

e.g. $mp3->enc("/tmp/tst.wav");

Oyez is a portable, standalone streaming audio server written in Python. Oyez is a standalone server capable of playing playlists of Vorbis or MP3, or of accepting input from an external encoder such as Oggenc or Lame.

Grip is a CD player and CD ripper/MP3-encoder for the GNOME desktop. It has the ripping capabilities of cdparanoia built in, but can also use external rippers (such as cdda2wav).
It also provides an automated frontend for MP3 encoders (presets for lame, bladeenc, l3enc, xingmp3enc, mp3encode, and gogo), letting you take a disc and transform it easily straight into MP3s.
The Ogg Vorbis format is also supported. Internet disc lookups are supported for retrieving track information from disc database servers.
Grip works with DigitalDJ to provide a unified, "computerized" version of your music collection.
Main features:
- Full-featured CD player with a small screen footprint in "condensed" mode
- Database lookup/submission to share track information over the net
- HTTP proxy support for those behind firewalls
- Loop, shuffle, and playlist modes
- Ripping of single, multiple, or partial tracks
- Encoding of ripped .wav files into MP3 files (as well support for OGG and FLAC)
- Simultaneous rip and encode
- Support for multiple encode processes on SMP machines
- Adding ID3v1/v2 tags to MP3 files
- Cooperating with DigitalDJ, my SQL-based MP3 jukebox
Enhancements:
- de.po: updated (G?tz Waschk)
- it.po: updated (Ceoldo Costantino)
- fr.po: updated (Eric Lassauge)
- pl_PL.po: added (Piotr Adamocha)
- id3.c: put a zero byte before the id3v1 track number (Vladimir Petrov)
- discdb.c: string parsing fixes to support i18n (Vladimir Petrov)
- discdb.c: better handling of non-UTF-8 local discdb files (Vladimir Petrov)
- various: tweaks to filesystem-safe character escaping (Vladimir Petrov)
- cdplay.c: allow retrieving of non-UTF-8 discdb entries (Vladimir Petrov)
- discdb.c: fixed a possible buffer overflow crash (Dean Brettle)
- grip.spec.in: added some missing BuildRequires (Stephen E. Dudek)
- configure.in: upped version to 3.3.1

mpegrec is a FREE, Open Source command-line tool for recording audio on Windows and Linux. It may be used to record direct-to-disk WAV files, and MP3 files. MP3 encoding requires an external MP3 encoder such as the lame encoder. Other encoders can be used with minimal changes to the source code.

Unlike other WAV recorders available online, mpegrec is free -- even on Windows. (MP3 encoding may require a licensed encoder.) The command-line inteface is easy to use -- easy enough you will not miss a silly GUI. If you have an audio card capable of hardware-mpeg encoding, mpegrec for Windows can utilize the cards features for direct-to-disk MP3 recording.

NOTE: mpegrec on Linux is slightly dated and may require porting to newer kernels. If you port mpegrec feel free to share it in accordance with the GNU GPL license. If you can make the package small enough, I will consider posting it here.

To install wavrec and mpegrec simply type make at the shell:

make

To install wavrec and a sym-link for mpegrec type make install:

make install

WideMP3 is a relatively simple distributed MP3 encoder. It works in a client-server fashion, with multiple servers and a client that feeds the PCM audio over a network connection to the server. The server sends back the encoded audio, which the client then writes to a file. The actual encoding is done via an external encoder, such as BladeEnc.

Installation is very simple simple.

Extract the source distribution, and compile and install as follows:

./configure
make
su
make install

Current supported platforms are:

Debian GNU/Linux 2.2 on Intel x86 and Alpha.
Debian GNU/Linux 2.1 on Intel x86
OpenBSD 2.7 on Intel x86

It should also work on FreeBSD, although this has not yet been tested. Positive and negative reports on different platforms will be appreciated, especially if accompanied by a patch to make it work.

If you want to contribute a patch, you must be willing for the patch to be released under the GNU General Public License. Patches should be in context diff format (diff -c) or unified diff format (diff -u).

Currently supported MP3 encoders:
Bladeenc 0.9x - http://bladeenc.mp3.no/
Positive and negative reports for different encoders will be appreciated, especially if accompanied by a patch to make it work.
