High Fidelity Pure Audio
High Fidelity Pure Audio, occasionally abbreviated as HFPA, is a marketing initiative, spearheaded by Sony Music Universal Music Group, for audio-only Blu-ray optical discs. Launched in 2013 as a potential successor to the compact disc, it has been compared with DVD-Audio and SACD, which had similar aims.
HFPA is encoded as 24-bit/96 kHz or 24-bit/192 kHz linear PCM, optionally losslessly compressed with Dolby TrueHD or DTS-HD Master Audio.
HFPA discs are compatible with existing Blu-Ray players.
Pure Audio Blu-ray refers to a different initiative launched by msm-studios in Germany in 2009.
As of November 2019, Deutsch-Grammphon is the most prolific publisher on the format, with Beethoven 250 having 3 Blu-Ray audio discs.
