Free lame mp3 encoding 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.

smp-encode is a compact utility that encodes groups of audio files in parallel to make use of multiple CPUs with single threaded encoders.
smp-encode project supports supports OggEnc and LAME.
Usage:
smp-encode is invoked with 3 mandatory arguments.
-e < encoder > where encoder is one of the available builtin modules, "lame" or "oggenc" as of now. encoder arguments are hardcoded in encoder.cpp, but in the future these will be defined on smp-encodes commandline.
-p < N > where N refers to any number over over 0. This will cause smp-encode to generate N processes to be used to encode the given files. Given files are evenly distributed.
The last mandatory argument is a choice between a list of files, either given explicitly or via wildcard (eg. ./*.wav) or the -d < directory > argument.
As of now, successful invocations dont display anything during runtime, in the future some progress info will be reported.
Compile:
You should be fine with just running make and then make install. This will generate a program named smp-encode that is stripped. And throw it in /usr/local/bin
If you need to add encoders or edit the argvs of them, encoder.cpp is where all that stuff is done.
Enhancements:
- A complete rewrite using the GTK+2.0 UI.
- Thread control (pause and cancel).
- Many options from LAME and oggenc are implemented in the GUI.
- Progress bars indicate individual thread progress.
- Many other tweaks and bugfixes related to the rewrite.

mp3CONVERT is a Kommander wizard for easy encoding mp3 songs. For example, when you need get your favourite album, which has 100mb to the cell phone with 40mb memory.

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.

FAME project is a set of tools for encoding multimedia content.

It currently consists in the following tools:

libfame

libfame is a video encoding library.

It can currently encode MPEG-1 and MPEG-4 rectangular video, as well as MPEG-4 video with arbitrary shape.

Compliance

Provide bitstreams compliant to the MPEG-1, MPEG-2 and MPEG-4 video standards.

Speed

Provide a fast implementation of the techniques used in MPEG standards.

Flexibility

Allow the user to choose between different options for speed, compression ratio and quality.

Portability Support many different platforms and architectures.

fame

fame is a multimedia encoder, which captures video from a video4linux device, and optionnaly sound, for MPEG encoding.

It is based on libfame and lame and thus supports the same output formats as these two libraries.

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
