The following is a list of compression formats and related codecs.
Audio codecs
Non-compression formats
- Linear Pulse Code Modulation (LPCM, generally only described as PCM) is most used format for uncompressed audio and it is also standard for Compact Disc Digital Audio; note that LPCM is in a computer usually stored in AIFF, WAV, AU container formats or as RAW audio format
- Audio Interchange File Format (AIFF, audio container format)
- FFmpeg
