[jfkaess]

The soon to be released CSNY 1974 live set is being released in July on CD and vinyl, but also in the Pure Audio Blu-Ray format as specced at the following site:

the CSNY 1974 music will be 192/24 bit. Can dbpoweramp rip this if my computer has a blu-ray drive?

But DVD Audio Extractor will be able to (although you may need AnyDVD to get around the protection).

Re: Pure Audio Blu-Ray

I use a combination of DVDfab (to extract the m2ts files), then eac3to (to extract the LPCM 2.0 as FLAC & chapter information), then Audacity to label & extract the individual tracks, before using mp3tag or dBPowerAmp to edit the metadata of the extracted individual FLAC tracks.
Bit of a process but the LPCM tracks in 24/96 or 24/192 are worth the trouble.
Listening the Blu-ray extraction of Tears for Fears 'The Hurting' in 24/96 transcoded by Asset (on Raspberry Pi) to WAV for a Naim ND5/XP5 player.

Re: Pure Audio Blu-Ray

This is interesting. I wondered how long it would be before blu-ray is utilised for audio only.

But I have a question re. bit rates. The standard seems to be 24 bit after reading this, but after ripping CDs to wav using dBpoweramp it says it's (only?) 16-bit? (currently listening to Agricantus Tuareg - fantastic, highly recommended as is The Hurting and Songs from the Big Chair). What if anything am I doing wrong? Same applies to Audacity when "ripping" vinyl - I set it to the maximum (32bit float, wav) but it is also only reporting 16 bit in Kinsky/Asset.

Re: Pure Audio Blu-Ray

Hi,
CDs are 16bit, under the Red Book Standard of 1984-ish. So dBPowerAmp CDRipper will extract the LPCM source at 16/44.1
I have not used Audacity to record, so I can't comment on whether this can be done in 24-bit.
However it does allow you to edit 24-bit files obtained by ripping & extracting the LPCM as FLAC, from SACDs, DVDAs, Blu-rays & downloads.
