High Fidelity Pure Audio, occasionally abbreviated as HFPA or BD-A, is a marketing initiative, spearheaded by Sony Music and Universal Music Group, for audio-only Blu-ray optical discs.^[2] Launched in 2013^[3] as a potential successor to the compact disc (CD), it has been compared with DVD-Audio 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.^[1]

HFPA discs are compatible with existing Blu-ray players.^[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]

As of November 2019, Deutsche Grammophon is the most prolific publisher on the format, with Beethoven 250 having three Blu-ray audio discs.
