Non-compression ================= * Linear pulse-code modulation (LPCM, generally only described as PCM) is the format for uncompressed audio in media files and it is also the standard for CD-DA; note that in computers, LPCM is usually stored in container formats such as WAV, AIFF, or AU, or as raw audio format, although not technically necessary. ** FFmpeg * Pulse-density modulation (PDM) ** Direct Stream Digital (DSD) is standard for Super Audio CD *** foobar2000 Super Audio CD Decoder (based on MPEG-4 DST reference decoder) *** FFmpeg (based on dsd2pcm) * Pulse-amplitude modulation (PAM) Lossless compression ====================== * Actively used ** Most popular *** Free Lossless Audio Codec (FLAC) **** libFLAC **** FFmpeg *** Apple Lossless Audio Codec (ALAC) **** Apple QuickTime **** libalac **** FFmpeg **** Apple Music *** Monkey's Audio (APE) **** Monkey's Audio SDK **** FFmpeg (decoder only) *** OptimFROG (OFR) *** Tom's verlustfreier Audiokompressor (TAK) **** TAK SDK **** FFmpeg (decoder only) *** WavPack (WV) **** libwavpack **** FFmpeg *** True Audio (TTA) **** libtta **** FFmpeg *** Windows Media Audio Lossless (WMAL) **** Windows Media Encoder **** FFmpeg (decoder only) ** Other *** DTS-HD Master Audio, also known as DTS++ and DCA XLL **** libdca (decoder only) **** FFmpeg (decoder only) *** Dolby TrueHD Standard for DVD-Audio in Blu-ray (mathematically based on MLP) **** FFmpeg *** Meridian Lossless Packing (MLP), also known as Packed PCM (PPCM) Standard for DVD-Audio in DVD **** FFmpeg *** MPEG-4 Audio Lossless Coding (MPEG-4 ALS) **** SSC, DST, ALS and SLS reference software (ISO/IEC 14496-5:2001/Amd.10:2007) **** FFmpeg (decoding only) *** MPEG-4 Scalable Lossless Coding (MPEG-4 SLS) Parts of it are used in HD-AAC. **** SSC, DST, ALS and SLS reference software (ISO/IEC 14496-5:2001/Amd.10:2007) *** RealAudio Lossless **** RealPlayer **** FFmpeg (decoding only) *** BFDLAC (BFD Lossless Audio Compression).
