The codecs are compatible with standard-compliant audio applications using one or more of these profiles.
MoreAmp is an audio player, transcoder, and CD ripper for Mac OS X, Mac OS 9, Windows, Unix, and Linux. It plays and creates ogg, flac, mp3, aac, m4a, mp4, wav, and aif files, and plays wma files. It features a 31-band equalizer, repeat loop, variable pitch/tempo, ram or ramdisk preload, and more.
RipIT is a command line program for ripping, encoding, and tagging MP3s that needs no user intervention. It is a wrapper for dagrab, cdparanoia, cdda2wav, LAME, Ogg Vorbis, Flac, Faac, Musepack, Wavpack, mp4als and ffmpeg. It supports the retrieval and submission of CDDB and MusicBrainz entries and cover art.
The GlobeCom Jukebox is a music jukebox with integrated CDDB-aware ripping and groupware functionality. It is completely configurable from the Web interface, seamlessly integrates ripping from CD to encoded MP3, and supports grouping of songs, peak adjustment, account management for access, streaming of jukebox or single song, themability, album handling, and online help.
MP3do is an "all in one" bash script. It is useful for decoding and mastering audio files. It can decode a list of MP3 or Ogg Vorbis files to WAV or CD-R, auto-convert poor quality MP3s to 44100Hz stereo, check whether all files fit on a CD, normalize all WAV files (adjust the volume to a standard volume level), and burn a CD.
Sonic-Rainbow is a Linux GUI multimedia player. It plays DVDs, VCDs, and video files. It plays CDs, rips CDs to Ogg, MP3, FLAC, and WAV files, and has an Ogg, MP3, FLAC and WAV player, as well as a playlist editor and a TAG editor to create and modify MP3, Ogg, and FLAC file tags. HTTP is used to download and locally store CD Info from Freedb such that the CD player, ripper, Ogg player, FLAC Player, and MP3 player are able to display CD track and artist information. The GUI playlist editor creates playlists containing single Ogg, FLAC, or MP3 files and directories of Ogg, FLAC, or MP3 files. It provides support for FM radio cards if installed.
Rip is a commandline-based Perl script which rips Compact Disc tracks to either Motion Picture Expert Group Layer 3 (MP3) files, Ogg Vorbis files, or FLAC files without user intervention between the steps of ripping. It supports cdparanoia and cdda2wav for ripping, BladeEnc, LAME, notLAME, and GOGO for WAV to MP3 encoding, oggenc for WAV to Ogg Vorbis encoding/tagging, FLAC for WAV to flac encoding. In addition, it supports CDDB for automatic renaming of files and MP3::Info for MP3 tagging.
mp3cleanup is used to tidy up various aspects of MP3 files, including filenames, ID3 tags, path, m3u playlists, and bitrate. This is particularly useful for hardware MP3 players that sometimes have arbitrary limitations on the files they work (well) with. It can operate on single files or on all the files contained in a directory.
