audio codecs
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)
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
- DTS-HD Master Audio – Optional lossless surround sound format used by HD DVD and Blu-ray, it was previously known as DTS++ and DTS-HD
- Free Lossless Audio Codec (FLAC)

- Meridian Lossless Packing (MLP), also known as Packed PCM (PPCM), it is the standard lossless compression method for DVD-Audio content
- Monkey's Audio (APE)
- OptimFROG (OFR)
- RealAudio Lossless
- RK Audio (RKAU)
- Shorten (SHN)

Other
Audio Video Interleave (AVI) is not a codec, rather it is a container format, like Matroska, that many video codecs can use.
