Free lame mp3 encoder audacity 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.

Versatile Encoder allows you to encode your own videos into good quality mpeg4 or h264. The input can be a sequence of files (as generated by blender), a file (if you want to recompress something) or a DVD/VCD (if you need to backup some movie).

This piece of software tries to guess good defaults and to help the user in his choices. It works at least under Windows and Linux, the coding platform is Linux.

It should work without a hassle under all BSD variants and probably under MacOSX too, report me if you get it working somewhere else.

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.

SimpleCDR-X was born in mid-June of 2001. It was clear to me that SimpleCDRs interface had limitations that could only be overcome by going to a GUI interface. I then proceeded to look at the various toolkits and then I discovered Glade.
Glade is perhaps one of the best programming utilities that I have found for Linux to date. It the development of a 2200 line interface much easier than it would have been otherwise. If Glade wasnt around I still might just be playing with the various toolkits instead of having a finished product. Glade allowed me to focus on functionality rather than trying to get the interface to look right with straight C code.
SimpleCDR-X like its brother SimpleCDR is a hybrid of C and C++. Most of the external utilities are managed by C++ classes called from the hybrid callbacks.c. The reason that I didnt opt to use GTK-- instead of the hybird was because most everyone already has GTK+, however, not everyone has GTK-- and some dont want to download a 1.5 MB file to compile or dig up the installation CDs.
Main features:
- Disc-At-Once CD copying
- Audio CD copying via cdrecord and CDparanoia or cdda2wav
- Audio CD Mastering
- MP3/OGG import via MADplay, LAME, or OGG123
- Import from CD via CDparanoia or cdda2wav
- Data CD Mastering
- Multi-session CD writing
- Rip tracks to wav
- Rip tracks to MP3/OGG on the fly via Blade Encode, LAME, or oggenc
- GTK+ Interface

PyMP3Cut is a Python command line tool designed to cut huge (> 100MB) MP3 files at high speed without requiring the extra disk space and processing time usually needed by visual audio editing tools, which convert the MP3 format to more easily manageable formats like WAV before doing anything.
It cuts and reads simultaneously according to the autodetected MP3 frame rate and a timeline passed as a command line argument. It doesnt currently deal with Variable Bit Rate (VBR) MP3 files, though.
Main features:
- PyMP3Cut is a Python command line tool designed to cut very huge MP3 files at a blazzingly fast rate without requiring the extra disk space and processing time usually needed by Audacity or other similar visual audio editing tools, which convert the MP3 format to more easily manageable formats like WAV before doing anything. The WAV conversion usually requires 10 times more disk space !
- PyMP3Cut doesnt convert anything : it reads and cuts simultaneously, according to the autodetected audio frame rate and a timeline passed as a command line argument. You can think of PyMP3Cut as being some sort of very careful chainsaw ;-) Since theres no back and forth MP3 conversion, theres no quality loss either !
- PyMP3Cut was designed to slice high quality MP3 recordings of day-long congresses into smaller per-speaker MP3 files. It only needs the exact same amount of disk space as the original file to slice, even less if you plan to skip some parts, which PyMP3Cut can do automatically if you use a specially formatted *SKIP* entry in your timeline. It was successfully used many times against several hundredths megabytes MP3 files.
Enhancements:
- Bill Eldridge added the --segment command line option.
