Lossless Audio Codecs The files in this directory are examples of lossless audio codecs. They all use luckynight.wav (bzip2'd in this directory) as the source material. The file is a 1-minute sample extracted from a CD (hence, 44.1 KHz, 16-bit stereo audio). The audio sample is compressed in a variety of formats. Each sample also attempts to store as much metadata as the format allows. E.g.: Title: "Lucky Night" Artist: "Jody Marie Gnant" Album: "Treasure Quest Soundtrack" Genre: "Soundtrack" Track Number: "9" Comment: "1-minute song sample demonstrating Brand-X's lossless audio compression" These are the compression formats: .ape: Monkey's Audio http://www.monkeysaudio.com/ .flac: FLAC (Free Lossless Audio codec) http://flac.sourceforge.net/ .la: Lossless Audio http://www.lossless-audio.com/ .m4a: Apple Lossless (alac) in QT/MP4 container http://www.apple.com/quicktime/ .mlp: Meridian Lossless Packing http://www.meridian-audio.com//p_mlp_in.htm .mp4: MPEG Audio Lossless Coding (ALS) http://www.nue.tu-berlin.de/menue/forschung/projekte/beendete_projekte/mpeg-4_audio_lossless_coding_als/parameter/en/ .ofr: OptimFROG http://losslessaudiocompression.com/ .pac: LPAC http://www.nue.tu-berlin.de/wer/liebchen/lpac.html .rka: RKAU http://rksoft.virtualave.net/index.html .rmvb: RealMedia Lossless audio in Real container http://www.real.com/ .shn: Shorten audio codec http://www.softsound.com/Shorten.html .tta: True Audio http://www.true-audio.com/codec.project .wma: Windows Media Audio 9 lossless in MS ASF container http://www.microsoft.com/windows/windowsmedia/default.aspx .wv: WavPack http://www.wavpack.com/
