The recent release of Neil Young's Archives on Blu-ray Disc piqued my interest in the Blu-ray format. The audio on Neil's Archives is at 24/192 for the Blu-ray box compared to 24/96 for the standard DVD box and 16/44.1 for the CD box. I have no desire to purchase a dedicated Blu-ray player, but I am very excited about the possibility of ripping audio off Blu-ray discs that I legally own. Ripping Blu-ray content is not the easiest task and I was initially unsure if I could actually get the audio from a Blu-ray Disc. Instead of purchasing the whole Archives box for a few hundred dollars, I picked up the Dave Matthews & Tim Reynolds: Live at Radio City Blu-ray Disc. This way I wouldn't have a box full of expensive unplayable discs if my little project went awry.
I needed a Blu-ray drive and the right combination of software to get started on this journey. I picked up a Pioneer BDC-2202 internal Blu-ray drive for about $150 at a local computer store. Since Mac OS X does not support Blu-ray, my plan was to use Windows Vista Ultimate 64-Bit running on a Boot Camp partition on my Mac Pro. Unfortunately it took me about 15 hours to realize this plan was not going to work as designed. The Blu-ray drive connects to a computer motherboard via a single SATA connector. Mac Pro computers have two available SATA ports on the motherboard so I thought I was in the clear. After fighting with Widows Vista for hours and hours trying to get it to recognize the Blu-ray drive I was ready to scrap the whole project. After some "Googling" I found out the available SATA ports in a Mac Pro do not function with any operating system other than OS X.
I then started to work my backup plan. I installed the Blu-ray drive into the Dell 530 that I configured for the Audiophile Reference Music Server for a Song article. The operating system immediately recognized the Pioneer drive and I was on to the software portion of this journey. Note: No special drive software or applications included with the drive are required.
Ripping Blu-ray discs can involve several processes and several software applications. The process for ripping video is a little different from ripping audio. I will concentrate on ripping high resolution audio off Blu-ray discs. Audio seems easier than ripping the whole shebang.
As previously stated, I used the Dave Matthews & Tim Reynolds: Live at Radio City Blu-ray Disc. I selected this disc in part because the back cover clearly displayed the details about the disc that I wanted to know. if only all Blu-ray discs were this detailed.
The output will be a single large WAV Audio file that can be imported into any playback application or converted to another format. I have yet to break up this single file into individual files for each track, but since it's a live concert I kind of like the continuity of a single file and I actually listen to the whole concert in a single sitting. I chose to convert to AIFF and add album art in iTunes. Once added to the iTunes library it's possible to look at the track information and see the Sample Size and Sample Rate to make sure the audio has not been downsampled. In an effort to save disk space downsampling can occur automatically by some applications designed to rip Blu-ray. tsMuxeR did not downsample the audio track in any of my tests.
Hi Eric - As a music lover and audiophile I think ripping Blu-ray is wonderful. Please let me know where you can find Neil Young content at 24/192 that is not on Blu-ray. The same goes for all the high resolution concerts like the Dave Matthews concert I ripped for this article. I realize you can download some hugh resolution material right now, but the selection is far to limited.
I did this exact same thing a few months ago for this exact same disc, I then edited the massive .wav file, cut out all of his talking between tracks, and created single .wav files for each track then converted them to flac. Worked out pretty well; I just did it for a higher fidelity version than the CD. It's 48hz 2.0 PCM, love it.
Wow, it's not so simple, but when someone else has done all the hard work for you, it all looks so easy doesn't it? What a pain that the SATA ports on the Mac are only for OSX use. Apple must have a real bee in its bonnet about Blu-ray, although PC notebooks with BD are slowly coming to the fore, not in droves but enough to give you a reasonably wide choice now.
General Question. The ripped AIFF file was 2.4GB. Depending on the sound editor application, which varies widely, how much RAM would you need to open that file, to mark, edit & save and not having to twiddle the fingers at the progress bar? Or would this be processor dependant as well? What would be a workable combination of RAM and Processor speed?

The amount of RAM doesn't have to be incredibly huge. I think 2 GB is a minimum but the more the better. I also think any dual core processor or better will work fine. As long as you aren't editing video this is the hardest task for a computer.
The time it takes to do this all varies. The Dave Matthews Disc was about 40 GB and probably took a couple hours to decrypt and copy to the hard drive (one step though). Then about 30 minutes to demux the audio from the huge m2ts file.
Very nice guide! I've been slowly moving my physical discs (DVDs, CDs, and HD/BDs alike) onto a portable Hard Disk I have until I've got a suitable server built. While trying to rip HD DVDs into lossless formats for playback, I did find that you can use eac3to to convert the demuxed output into files or formats of your choice; personally, I've converted the lossless audio tracks on my movies into FLAC format rather than WAV, just to cut down on space used. It's something worth looking into, and eac3to is remarkably fast I've found: it auto-detects the input bit-depth and sampling rate, and will convert it into whatever you name the file as (Including DD and DTS with proper encoding libraries, in case you need to downsample the audio for whatever reason). It'll even work on Dolby TrueHD and (possibly) DTS-HD MA/HR.
Hi ggking7 - I tried dumpHD during this project, but had many problems with it. I love the fact it is a Java app and can run on any OS that supports Java, but the difficulty of using it was a downer for me. Hopefully it was just my experience!
There are three kinds of lossless blu-ray audio tracks: LPCM, TrueHD and DTS-HD Master Audio. LPCM is not a problem to demux, but I am pretty sure the others will demux core only with tsMuxer. The core is usually a 640/1536 kbps DD/DTS track.
Additionally there are three high bitrate lossy codes: DTS-HD, DTS-HD High Resolution and Dolby Digital+. DTS-HD is usually full bitrate normal DTS and should not be a problem. DTS-HD High Resolution will probably demux core only and Dolby Digital+ is probably not supported.
FYI I bought the NY box and also picked up the new OPPO BR player because I needed a decent player and the OPPO seemingly is a universal player. I also have a computer with a Lynx card and a Berekey Alpha Dac. Interesting enough I bought the Oppo to bypass the hassles of ripping BR audio and to simply have a stand alone player to output to the BAD.
All this seems simple enough but I have run into some hiccups. The Oppo puts out perfect data for all my other DVD-A discs and DVD-V discs yet the data output from the BR audio is only 48K. Tried all the configurations for the Oppo to no avail.
Neil Young's appreciation of hi-res music is well documented. Based on that, it would have been nice if he just stuck 24/192 tracks on an HDAD DVD audio and made it a lot easier for all of us (himself included). I guess he thought we needed to see his films too so he went with blue-ray.
More than likely, it's something wrong with the settings on the player side if you're getting 24/48 instead of 24/96 or higher. HDMI can be confusing once you get into the nitty gritty settings of the spec, though assuming your player can output bitstream (it should be able to) and your receiver is HDMI 1.3a+ with the ability to decode the audio codecs at proper resolution, you should go that route. If, however, you have a player that can decode TrueHD and DTS-HD MA, it may be worth it to decode on the player and pass 7.1 channel 24/192 audio as LPCM. Only HDMI 1.3 or newer receivers/processors can decode the lossless codecs, though many players are dropping lossless decoding support on-board when they can to cut costs, relying instead on bitstream support since most consumer receivers support it or can decode the lossy cores of the soundtracks.
EDIT: This assumes you're using HDMI. Analog and SPDIF outputs on BD decks are subject to DRM and/or connection restrictions, including a no-analog-video support starting in 2013 (So all you CRT Projector owners without HDMI or HDCP, get your decks now!)
Chris, that's aacskeys. On Linux the compiled library is called libaacskeys.so. Do you know what version of aacskeys you tried? The latest is 0.4.0a which is the same as 0.4.0 for our purposes. I found some info on OS X support here:
"Due to the nature how Mac OS X handles low level I/O operations there are some remarks and open issues. aacskeys can use 2.5 paths to communicate with the drive. First it can use exclusive access to send commands to the drive, this has some drawbacks however so this needs to be enabled explicit by using the command line switch --exclusive-io. You can't get exclusive access easily because Finder will grab the drive when a disc gets inserted, to overcome this problem aacskeys unmounts the disc, this requires root rights currently. This has the side effect that as soon as aacskeys releases the drive Finder grabs it again and autorun gets started. This access path provides the same features as aacskeys has under windows and linux, the only benefit of using it is that only this path allows the usage of the XBox hack, there are no other advantages currently.
