List of computer file compression formats

The following is a list of compression formats and relatedcodecs.

Audio compression formats

[edit]

Main article:Audio coding format

Non-compression

[edit]

Linear pulse-code modulation (LPCM, generally only described asPCM) is the format for uncompressed audio in media files and it is also the standard forCD-DA; note that in computers, LPCM is usually stored incontainer formats such asWAV,AIFF, orAU, or asraw audio format, although not technically necessary.
- FFmpeg
Pulse-density modulation (PDM)
- Direct Stream Digital (DSD) is standard forSuper Audio CD
  - foobar2000 Super Audio CD Decoder (based on MPEG-4 DST reference decoder)
