Free mp3 encoder ubuntu 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.

neostrada-sagem-ubuntu is a script, that configures ubuntu for networking with Sagem fast800 (neostrada tp).

Booting Ubuntu To RAM is an article aims to document the process of creating a customized Ubuntu that loads an image from the hard disk to RAM, then boots an entire Ubuntu session out of RAM. It is intended for intermediate to advanced Ubuntu users who are familiar with the shell, and may have limited experience customizing the livecd (LiveCDCustomization) and shell scripting. We will customize a LiveCD and copy it to the hard drive, and make a few modifications to bootup scripts so that it copies to RAM via our good friend tmpfs.
WARNING: The author asserts that this procedure works for him, but cannot guarantee that this procedure works for anyone else. Although this procedure is meant to be 100% safe, it is feasible that there may be mistakes, or a chance of misunderstanding the instructions in a manner that causes loss of data. Please make a backup and do not attempt on mission critical systems. Read through this article thoroughly, and do not attempt if you do not comprehend or feel comfortable about any of the instructions!
CAUTION: I hope this is intuitively obvious, but Ill humor you and state it bluntly: Changes you make under the live session are NOT saved and WILL BE LOST when you reboot or shut down. Dont save anything important to the "home directory" and expect it to still be around! If you want to save data permanently, mount a permanent medium (such as your hard drive), plug in a thumbdrive, or use some network functionality built into Ubuntu to save your data to a non-volatile destination.
There are many cases where one would like to boot Ubuntu to RAM:
- Performance: The desktop performance is dramatically improved. A 400MB squashed filesystem in RAM, that holds 1200MB of data, is read back on a 1.6GHz Core Duo in about 3 seconds, including decompression time.
- Power, Noise, Durability: Although modern hard disks dont use much power compared to other system components, this may still be important for some. In laptops, hard disks are often the noisiest components, so this setup can reduce system noise. With the hard disk spun down, a laptop can potentially withstand greater shocks without damage.
- Abrupt poweroff: Since the hard disk is only momentarily used in read-only mode during boot, then never touched again, there are few or no negative consequences of an abrupt poweroff. If a system is used where power is inconsistent, or the system is regularly used in a context where fast shutoffs are required, this is very handy.
- Privacy: Anything you do in this session are lost when you reboot or power off. This is great for kiosks or other systems where permanent modification are not desired. (Note that by default the livecd user has full sudo access, so potentially a malicious user can still make permanent changes by mounting the hard drive and following this HOWTO)

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;

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.
