The following is a list of compression formats and related [[codec]]s.
==
{{Main|Audio coding format}}
===
* [[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 format (digital)|container formats]] such as [[WAV]], [[Audio Interchange File Format|AIFF]], or [[Au file format|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)
