List of codecs

The following is a list of compression formats and relatedcodecs.

Audio compression formats[edit]

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 formatssuch asWAV,AIFF,orAU,or asraw audio format,although not technically necessary.
