High Fidelity Pure Audio (HFPA) is a marketing initiative, spearheaded by the Universal Music Group, for audio-only Blu-ray optical discs.[2] Launched in 2013[3] as a potential successor to the Compact disc, it has been compared with DVD-A and SACD, which had similar aims.[4][2]
HFPA is encoded as 24-bit/96 kHz or 24-bit/192 kHz linear PCM ("high-resolution audio"), optionally losslessly compressed with Dolby TrueHD or DTS-HD Master Audio.[5]
Pure Audio Blu-ray refers to a different initiative (but with some goals in common) launched by msm-studios in Germany in 2009.[4]
