List of codecs

The following is a list of compression formats and related codecs.

Audio compression formats

Main article: Audio coding format

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)
