Free mp3 encoder freeware software for linux

KmPg2 is a very simple to use MPEG2 encoding wizard that allows the user to create high quality DVD compatible MPEG2 streams, without requiring any technical knowledge.
Creating high quality MPEG2 streams involves a lot more than simply feeding the input video to mpeg2enc/transcode/mencoder/etc.
The input video needs to be carefully prepared by pulling it through a chain of stream processing tools like low-pass filters, color correction filters, static and dynamic chroma and luma noise filters, scalers, and so on.
This processing chain needs to be tuned in such a way that all irrelevant data (like noise) is removed before the video enters the encoder. KmPg2 uses the video processing / encoding tools from the MJPEGTools project to achieve this.
KmPg2 features a profiler that enables the user to interactively create custom pre-processing pipelines that are optimised for a specific type of video material. These preprocessing pipelines (profiles) can be stored and used with the actual encoding wizard.
For example, you could create a profile that is designed especially for restoring a single aging VHS tape, or you could create a profile tuned for your digital camcorder and re-use it for every new recording that needs to be encoded.
At this moment KmPg2 accepts only one format of input video: Raw Sony DV video streams. This is the video format that most people use nowadays for high quality video processing and editing. Support for using AVI files for input is expected in future versions.

iPod Video Encoder is a command line tool for convenient encoding of video files for use on iPod video. iPod Video Encoder project uses the ffmpeg tool for the actual encoding.
It features recursive encoding of all files in a directory, and generating a podcast.xml file for convenient use in iTunes.
It can be used in a cron job that periodically checks directories for new files and encodes them without user intervention.
Main features:
- Encoding of single files
- Optional specification of a/v bitrates
- Recursively encode all files in a directory
- Generating a podcast.xml for convenient use in iTunes
Options:
--version show programs version number and exit
-h, --help show this help message and exit
-R, --recursive Process directories recusively
-f, --force Force re-encode existing iPod videos
-t, --test Only encode first 10 seconds, to produce test videos
-e EXTENSIONS, --extensions=EXTENSIONS
Comma separated list of input extensions. Default: avi
-i IPODEXT, --ipodext=IPODEXT
iPod extension. Default: .ipod.mp4
-b VIDEO_RATE, --video-rate=VIDEO_RATE
Video bit rate, in kbps (default: 1024)
-a AUDIO_RATE, --audio-rate=AUDIO_RATE
Audio bit rate, in kbps (128)
-W WIDTH, --width=WIDTH
Video width, in pixels (default: 320)
-H HEIGHT, --height=HEIGHT
Video height, in pixels (default: 240)
-P, --pretend Do not really encode, just print out the ffmpeg
commands which would be executed
-v, --verbose Enable verbose output
Podcast options:
-p, --podcast Generate a podcast.xml file for each directory.
--podcast-documentroot=PODCAST_DOCUMENTROOT
Podcast document root; eg. /var/data/Movies/
--podcast-baseurl=PODCAST_BASEURL
Podcast base URL; eg. http://localhost/
Enhancements:
- Only uses the -e option for processing directories.
- The default ipod extension is now _ipod.mp4 for Windows compatibility.
- The README file has been extended with information on the .ipod-encoder settings file.
- The program no longer crashes when HOME is not set on Windows.
- --width and --height parameters have been added.

mp3cue cuts an input MP3 file according to the information stored in a .cue file (for example multiple tracks of DJ mix), and writes the output to multiple MP3 files.

poc is a mp3 and ogg streamer supporting following protocols:

HTTP (mp3 and ogg)
RTP (RFC 2250) (mp3 only)
RTP (RFC 3119) (mp3 only)
homegrown FEC protocol (mp3 only)

It should work under any POSIX platform, and does not require any additional library. You need a C99 compiler though.

poc is still beta software, ipv6 and ogg support was not tested extensively.

poc includes mp3cue, a mp3 CUE cutter, and mp3cut, a mp3 command-line editing tool.

MP3c is a special program for converting audio-cds to ogg/mp3-format. It is a frontend for every grab-program and mp3-encoder. Nearly every program should be supported. MP3c has two different run-modes: An interactive mode with a menu-enviroment (based on curses-lib), which can used on textconsoles as well under X11, and a batchmode, which allows automatic encoding of cds inside shellscripts (eg at night within cronjobs).
There are two different possibilities for encoding (depends on your ripper and encoder): Non-Fly encoding, where an audio-track is first grabbed from cds and then encoded, and On-Fly encoding, where grabbing and encoding is one step. Normally you should refer to Non-Fly encoding, since your cdrom-drive hasnt to work all the time, and some encoder produces a "click" at the beginning of mp3/ogg-files if On-Fly encoding is used. The only disadvantage of Non-Fly encoding is, that there is a temp-file, which can grow up to 50-100 MB sometimes.
Information about songtitle on your cds are received with help of CDDB database. In contrast to other programs, an CDDB-entry is detailed analyzed to find every information even for sampler-cds.
Creation of filenames is userdefined. You can use pattern to constitute the appearance of your mp3-files individually. Furthermore you can decide how spaces within filenames should be handled (you can allow them, convert them to underscores "_" or just kill them).
Interessting is the possibility of shellscript creation, which contains all functionality for encoding your cds. You can start these scripts as daemon-processes or run them at night inside a cronjob.
Recommended programs for the use of MP3c are: CDparanoia as audio-cd grabber, Encoder as MP3-encoder and MP3info for creating MP3-ID-tags. For OGG use oggenc. If you need, you can download these programs here, or a complete package with these programs inside. Furthermore you can download runable binaries, but only for glibc 2.1 (linux i386) at the moment. If you like to create RPMs and/or binaries for other systems and libraries, please send these to me, so that I can put it on my page.
Enhancements:
- Switched to CDDB protocol level 5 to support detection and saving of year and genre information.

MP3::Daemon is a daemon that possesses mpg123.

SYNOPSIS

MP3::Daemon is meant to be subclassed -- not used directly.
package MP3::Daemon::Simple;

use strict;
use vars qw(@ISA);
use MP3::Daemon;

@ISA = qw(MP3::Daemon);
Other perl scripts would use MP3::Daemon::Simple like this:
my $socket_path = "/tmp/mp3d_socket";

# start up a daemon
MP3::Daemon::Simple->spawn($socket_path);

# get a socket thats good for one request to the daemon
my $client = MP3::Daemon::Simple->client($socket_path);

print $client @command;

MP3 Jukebox-Tk is an organizer/jukebox for local mp3 collections. MP3 Jukebox-Tk sorts your mp3 files by band and presents a jukebox style interface to let you choose which ones to play.

It then passes these off to XMMS for playing. It also keeps stats on what you listen to, and can use those stats to generate a weighted random playlist for you. Non-weighted (truly random) playlists are also available.
