[edit] Audio codecs
[edit] Non-compression formats
- Audio Interchange File Format (AIFF, container format)
- Resource Interchange File Format (RIFF, container format)
- WAV – Microsoft "WAVE" format (format supports compression, but it is rarely used)
- Linear Pulse Code Modulation (LPCM, generally only described as PCM, note that AIFF, WAV and MLP are all derivative forms of LPCM)
- Pulse-amplitude modulation (PAM)
[edit] Lossless data compression
- Apple Lossless Audio Codec (ALAC)
- Direct Stream Transfer (DST)
- Dolby TrueHD – Optional lossless surround sound format used by HD DVD and Blu-ray, it uses MLP but adds higher sample rates, bit rates, and more channels
