LTAC allows for lossless audio compression of PCM coded audio signals (16 bit), i.e. decoding results bit for bit in the original bit stream of the PCM coded signal. In contrast to LTAC there exist a lot of lossy coding algorithms like MPEG, ATRAC and AC-3, which yield higher compression ratios but in any case lead to coding distortions - nothing for HiFi purists and professionals.
User comment: Please note that LTAC is not developed further; it has a successor called LPAC; the rating refers to LPAC which is really an excellent small program. Created: 04/02/1999 by Mark Nelson |

| SourceCode content, NonCommercialProgs content, Lossless_Audio_Coding area | WavPack allows you to losslessly compress (and restore) both 16 and 24-bit audio files in the .WAV format. Unlike "lossy" compression schemes (like MP3) that discard information, WavPack converts the audio data into a more compact form so that the restored files are digitally identical to the original source. It's somewhat like the file compression portion of WinZIP except that it's optimized for audio data. Like other lossless compression schemes the data reduction varies with the source, but it is generally between 25% and 50% for typical popular music and somewhat better than that for classical music and other sources with greater dynamic range.

| Zlib area, NonCommercialProgs content, Lossless_Audio_Coding area | This project aims to define a standard for the lossless compression of MIDI patch files.

| NonCommercialProgs content, Lossless_Audio_Coding area | DualStream is aimed at filling the big gap between perceptual coding and lossless coding. The goal is to offer real transparent audio coding (not only perceptually transparent) at half or less the bitrate generally used by lossless coding, and also to permit progressive consistent increase of the quality level, until lossless coding is reached. To eliminate the problem of choosing between lossless and near lossless, DualStream has an option to create a correction file, which may be eventually stored separately and used at a later time to restore the original. The advantage is that the two files (near lossless and correction) have together approximately the size of the lossless coded original file. Created: 12/10/2003 by Mark Nelson |

From the web site:crip is a terminal-based ripper/encoder/tagger tool for creating Ogg Vorbis/FLAC/MP3 files under UNIX/Linux. It is well-suited for someone seeking to make a lot of files from CDs and have them all properly labeled and professional-quality. One thing to note is that the author of this free package has removed MP3 support, and limits you to Ogg Vorbis or FLAC for encoding.

FLAC is an open-source project which specifies a lossless compressed audio format and provides an encoder, decoder, and several player plugins. Aside from yielding better compression than Shorten, the format supports sample-accurate seeking and many other features useful for streaming and archival.
The format is supported by a number of software and hardware players.
