Perspective
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.
- 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)
