I'm new to high-definition audio, I've got some tools, I bought a few blu-ray audio discs. Most of these blu-ray discs have a PCM 24/96 or 24/192 track. Minotaur has a DTS-HD Master Audio track, which shows up as 48khz.
If you look at the press releases and the website http://www.pixiesmusic.com/minotaur/ it says, a little ambiguously, "Blu-ray audio mastered for 5.1 surround sound and 2 channel stereo at 24/192"
So, is that DTS-HD MA track 24/192? Or does that sentence really mean that only the master was 24/196?
I've read that DTS-HD MA is lossy/lossless, where it has a lossy core and then it has the "make-up" bits, and it only sends these leftover bits if the destination can handle it.
When I try to get the audio track, I'm getting 24/48. Is there a trick to getting 24/192? |

I honestly have no idea, but there is some detail/argument here which might help:
http://forums.stevehoffman.tv/threads/new-pixies-box-set-minotaur-deluxe-edition.180802/page-6 "Spectral analysis of the 24/192 waves showed no frequencies above 23kHz for any of the files. So it appears the stereo tracks on the Blu-ray were upconverted from 48kHz files. I don't know how to tell if the word length was also upconverted but, even if they are true 24 bit, I still find it disappointing."

How's the 5.1 version mixed ? it possible to isolate vocals/guitar/drums on this mix ? Would be great to make backing tracks to play a long.

if you're a member of what.cd there's some discussion about this on the minotaur upload here: https://what.cd/torrents.php?id=663780 you can even download the 192 kHz, 5.1 channel collection which is a mere 18.6GB!
there was some instrumental versions floating round which i believe were "made" by using these 5.1 rips. can't find them on my hard drive, so maybe they're on youtube....

Thank you for this. I think I understand now, the 48khz is the Core audio and I need better tools to get at the lossless data.
I wonder if the guy in the stevehoffman.tv thread didn't get the stream properly, even though he seems to have used all the right tools.
I wont have much time for this for a while, so it may be easier to find the work already done!
I'll try to remember to look into the 5.1 tracks the next time I have the boxset out. |

There's some instrumentals here for example: http://www.guitarbackingtrack.com/bts/Pixies,_The.htm. Some of them were probably ripped of the 5.1 mix as you said. I'd really like to have the whole Pixies discography in this format, just to be able to de-compose all those tracks and discover all the little secrets.
Thanks for the tip, but I'm not really a torrent guy. I'd like to actually buy those records in 5.1 mix (blu ray). Are they only available on the limited (signed) version of the box set ? Or all versions ?
Thanks

that website (from picking gouge away at random) aren't what I was meaning. i meant the proper album versions with the vocals removed. like this one: https://www.youtube.com/watch?v=llKSjpKx0y4
hell, using he search function there's a thread from 2010 that I started (no wonder I couldn't remember) that talks about them. Seeing as I uploaded some, I must have copies floating round somewhere..... http://forum.frankblack.net/topic.asp?TOPIC_ID=20184
and they're sourced from the Rock Band multitracks, so nothing to do with minotaur at all

Hey, thanks for clearing that up.
Kind of a shame they didn't deliver a proper mix on the 5.1 versions of the Minotaur box set if those "unmixed" master tapes actually exists.
If you ever find any of your files, i'm hghly interested !

OK, recap: - regarding those tracks without guitar that have been dumped from those Guitar Hero type games: the whole Doolitte album is available, plus "Sad Punk" from Trompe (they're all available here: http://www.guitarbackingtrack.com/bts/Pixies,_The.htm). That's all and that answers my question.
Blu Ray 5.1 mix merely contains the original mix, plus some reverb on the rear speakers. That's not a proper 5.1 remix. Except for quality, that's pretty useless.

I've pulled apart the 5.1 tracks [for TLM] for a quick listen and they all sound like they are going through a flanger. So each channel is like a piece of the whole track.
The stereo track does seem to be real 24/192. I don't know if I have a fequency analysis tool, but the programs I'm using seem happy to give me lots of bits. If I download Audacity, I'll run some tests. |

I've run a spectrum analyser on the files and it does seem to be, there is very litte information above 22khz for the most part. Doolittle seems to have 48khz and the live album looks like it goes to 24khz.
I think I must have done something wrong. |

Have you tried phasing different channels, so same frequencies are cancelled out? I tried this with with the Letter to Memphis album version and instrumental version to get the acapella but unfortunately they are different recorings and slightly different speeds
Oh my golly! |
