Free flac to mp3 software for linux

Marlin is a sample editor for Gnome 2. It uses GStreamer for file operations and for recording and playback, meaning it can handle a great number of formats and work with most sound systems.
Main features:
- Can load from a large number of media formats (.mp3, .ogg, .wav, .au, .flac, .mpg, .avi...)
- Can save to many formats (.mp3, .wav, .au, .ogg, .flac...) and use the Gnome-Media profiles
- Can handle large files with no problems
- Handles cut, copy, paste, replace and mix operations
- Infinite levels of Undo/Redo and everything should be undoable
- Fully Gnome 2 HIG compliant
- Can record from a variety of sources (ALSA, OSS, esd, arts)
- Playback
- Can extract audio from CDs (with optional musicbrainz lookup)
- Gnome-VFS support
- Horizontal and Vertical scaling
- Uses GStreamer

Apache::MP3::Resample subclasses Apache::MP3::Playlist to allow the user to downsample audio files before streaming them. This allows users on slower connections to stream songs. When this module is installed, a menu of bitrates is presented in the upper right-hand corner of the screen. The user can choose from one of the bitrates, or select a mode that performs no resampling. The selected bitrate is maintained in a persistent cookie so that resampling is performed whenever the user returns to the site.

This module requires a command-line MP3 encoder to resample and reencode the audio data. If not otherwise specified, Apache::MP3::Resample will try to use the Open Source Lame MP3 encoder. This utility is available at http://www.sulaco.org/mp3. Version 3.90 was used during the development of this module. Your results with other versions may vary.

When you install Lame (or the encoder of your choice), be sure to place it in a directory located in Apaches PATH so that the module can find them at run time. You may need to set the PATH environment variable during Apaches launch, or by explicitly adding a SetEnv directive to the Apache configuration file.

You should be aware that the decoding/reencoding process is CPU-intensive, and server performance may degrade as the number of simultaneous users increases.

&MP3FS is A read-only FUSE filesystem which transcodes audio formats (currently FLAC) to MP3 on the fly when opened and read. This was written to enable me to use my FLAC collection with software and/or hardware which only understands MP3. e.g. gmediaserver to a netgear MP101 mp3 player.
MP3FS is also a novel alternative to traditional mp3 encoder applications. Just use your favorite file browser to select the files you want encoded and copy them somewhere!
How it Works:
When a file is opened, the decoder and encoder are initialised and the file metadata is read. At this time the final filesize can be determined as we only support constant bitrate mp3s.
ID3v2 tags are created from the vorbis comments in the flac file. They are located at the start of the file. As such, an application scanning a directory to read tags should not cause too much of a performance hit as the actual encoder does not need to be invoked (depending on how much data the read asks for).
A special exception to this is when an application tries to read the very last block first. Many applications do this to look for an id3v1 tag (stored in the last 128 bytes of the file). When this is detected, the filesystem simply return zeros (I dont support id3v1 tags). This dramatically speeds up applications, however it could potentially lead to corrupt mp3 files if the zeros are still in kernel cache when the application comes back to read the actual audio sequentially. In my experimentation this has not happened, I always get another read for the final block.
As the file is read, it is transcoded into an internal per-file buffer. This buffer continues to grow while the file is being read until the whole file is transcoded in memory. The memory is freed only when the file is closed. This simplifies the implementation.
Seeking within a file will cause the file to be transcoded up to the seek point (if not already done). This is not usually a problem since most programs will read a file from start to finish. Future enhancements may provide true random seeking.

Usage:
mount your filesystem like this: (you will probably have to be root)
mp3fs musicdir bitrate mountpoint [-o fuse_options]
e.g.:
mp3fs /mnt/music 256 /mnt/mp3 -o allow_other,ro

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.

Boss Ogg is a server based music (ogg/mp3/flac) player. Written in Python/C, uses sqlite for a database backend, and xml-rpc for client/server communication. Clients are released for php, sdl and curses(geezer).
Compilation and installion are very typical for unix applications. ./configure to configure the program to your system (./configure --help will show you some flags). make will build the python modules. make install will install the program.
