List of codecs

From Wikipedia, the free encyclopedia

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

Audio compression formats[]

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.
