Free flac to mp3 conversion software for linux

MOV, MP4 conversion service is final and working version of my script, which I use to convert files supported by ffmpeg to MOV / MP4 format, supported by my iPod Video G5.

Everything was tested to be easy to use (finally, after installation). If You have any problems with it, just let me know - Ill try to help as far as I can.

INSTALLATION:

Just download "avi2mov" script, and save it in /usr/sbin/ directory (You can save it in any directory, but take care later, because i assume, youve saved it in /usr/sbin/ :) ).

After this, You need to set proper permissions, so use chmod:

chmod +x /usr/sbin/avi2mov

Finally, You need to add this converter to Service Menu. Create file

/usr/kde/3.5/share/apps/konqueror/servicemenus/convert-avi-to-mov.desktop

with Kate for example, and copy and paste this code:

[Desktop Action MediaConvertFile]
Exec=/usr/sbin/avi2mov %U
Icon=reload
Name=Convert selected file to mov / mp4 ...
[Desktop Entry]
Actions=MediaConvertFile
Encoding=UTF-8
Icon=reload
ServiceTypes=video/*
ExcludeServiceTypes=kdedevice

Dynamic MP3 Lister was a project I started a long time ago to create dynamic lists of MP3s quickly and easily.

Features MP3 Information extraction for things like bitrate, channels, playtime and more.

Please note that this script is discontinued, and is only shown here now as an example of my work.

Audio Convert is a script to convert Wav, Ogg, MP3, MPC, FLAC, APE, or WMA files into Wav, Ogg, MP3, MPC, FLAC, or APE files.
It has an easy-to-use interface that makes it possible to fill in the tags for a few formats and choose the quality of compression.
The script was initially designed for the nautilus file browser, and can be easily installed into nautilus by copying it to the nautilus-scripts directory, at which point you can right click on the desired audio file(s) and choose "audio-convert" from the "scripts" menu.
The script is also known to work on rox or directly from a shell.
Enhancements:
- The installer was modified to create the directory it is supposed to create.

AudConvert is an application that is designed to take any audio format and convert it to any other audio format.
The idea for AudConvert came from my need to turn my Ogg Vorbis collection into MP3s for portable devices.
Yes, this process sometimes will result in lower quality, but sometimes it must be done.
Main features:
- Input any directory of files, get out the same directory structure (or flat directory) of newly encoded files.
- Multi-threaded: Encode up to 8 files simultaneously.
This is the first release of this software and it needs a lot of testing.
Supported Inputs:
- Ogg Vorbis (oggdec)
- MP3 (mpg123)
- FLAC (flac)
Supported Outputs:
- Ogg Vorbis (oggenc)
- MP3 (lame)

Sound Converter project can convert sound files to other formats.

A simple sound converter application for the GNOME environment. It reads anything the GStreamer library can read, and writes WAV, FLAC, MP3, and Ogg Vorbis files.

audiokonverter is a small utility to easily convert from OGG, MP3, AAC, M4A, FLAC, WMA, RealAudio, Musepack, Wavpack, WAV and movies to MP3, OGG, M4A, WAV and FLAC in Konqueror by right-clicking on them.
It needs oggenc, oggdec, faac, faad, flac, mplayer and lame to work. id3lib is optional for full functionality. Also optional are vorbis-tools and metaflac for handling other metadata. See README how/where to get that software.
Enhancements:
- MP3 metadata: switched from id3tag (V1 and V2) to id3v2 (V2 only) as suggested by Robert Turnbull

FLAC is Free Lossless Audio Codec. Grossly oversimplified, FLAC is similar to MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality.
This is similar to how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio, and you can play back compressed FLAC files in your favorite player (or your car or home stereo, see supported devices) just like you would an MP3 file.
FLAC is freely available and supported on most operating systems, including Windows, "unix" (Linux, *BSD, Solaris, OS X, IRIX), BeOS, OS/2, and Amiga. There are build systems for autotools, MSVC, Watcom C, and Project Builder.
The FLAC project consists of:
the stream format
reference encoders and decoders in library form
flac, a command-line program to encode and decode FLAC files
metaflac, a command-line metadata editor for FLAC files
input plugins for various music players
When we say that FLAC is "Free" it means more than just that it is available at no cost. It means that the specification of the format is fully open to the public to be used for any purpose (the FLAC project reserves the right to set the FLAC specification and certify compliance), and that neither the FLAC format nor any of the implemented encoding/decoding methods are covered by any known patent. It also means that all the source code is available under open-source licenses. It is the first truly open and free lossless audio format.
Main features:
- Lossless: The encoding of audio (PCM) data incurs no loss of information, and the decoded audio is bit-for-bit identical to what went into the encoder. Each frame contains a 16-bit CRC of the frame data for detecting transmission errors. The integrity of the audio data is further insured by storing an MD5 signature of the original unencoded audio data in the file header, which can be compared against later during decoding or testing.
- Fast: FLAC is asymmetric in favor of decode speed. Decoding requires only integer arithmetic, and is much less compute-intensive than for most perceptual codecs. Real-time decode performance is easily achievable on even modest hardware.
- Hardware support: Because of FLACs free reference implementation and low decoding complexity, FLAC is currently the only lossless codec that has any kind of hardware support.
- Streamable: Each FLAC frame contains enough data to decode that frame. FLAC does not even rely on previous or following frames. FLAC uses sync codes and CRCs (similar to MPEG and other formats), which, along with framing, allow decoders to pick up in the middle of a stream with a minimum of delay.
- Seekable: FLAC supports fast sample-accurate seeking. Not only is this useful for playback, it makes FLAC files suitable for use in editing applications.
- Flexible metadata: New metadata blocks can be defined and implemented in future versions of FLAC without breaking older streams or decoders. Currently there are metadata types for tags, cue sheets, and seek tables. Applications can write their own APPLICATION metadata once they register an ID
- Suitable for archiving: FLAC is an open format, and there is no generation loss if you need to convert your data to another format in the future. In addition to the frame CRCs and MD5 signature, flac has a verify option that decodes the encoded stream in parallel with the encoding process and compares the result to the original, aborting with an error if there is a mismatch.
- Convenient CD archiving: FLAC has a "cue sheet" metadata block for storing a CD table of contents and all track and index points. For instance, you can rip a CD to a single file, then import the CDs extracted cue sheet while encoding to yield a single file representation of the entire CD. If your original CD is damaged, the cue sheet can be exported later in order to burn an exact copy.
- Error resistant: Because of FLACs framing, stream errors limit the damage to the frame in which the error occurred, typically a small fraction of a second worth of data. Contrast this with some other lossless codecs, in which a single error destroys the remainder of the stream.
What FLAC is not:
- Lossy. FLAC is intended for lossless compression only, as there are many good lossy formats already, such as Vorbis, MPC, and MP3 (see LAME for an excellent open-source implementation).
- SDMI compliant, et cetera. There is no intention to support any methods of copy protection, which are, for all practical purposes, a complete waste of bits. (Another way to look at it is that since copy protection is futile, it really carries no information, so you might say FLAC already losslessly compresses all possible copy protection information down to zero bits!) Of course, we cant stop what some misguided person does with proprietary metadata blocks, but then again, non-proprietary decoders will skip them anyway.
