It's a funny thing when I have friends over and they see me just simply listening to my records instead of doing somthing else, you know like the only thing music is good for is background noise. Strange times we live in.

Yes. I still listen to music "actively" as apposed to having it in the back ground and half listening. I have one floor of my house dedicated to music. Unfortunately, I don't have as much free time as I used to, but I still do it when I can. We are a dieing breed.

Sorry to bump an old thread but couldn't find where else to ask my question.

Would it be possible to put CD-quality audio on a BD-R disc? And if so, how many minutes of standard stereo 2-channel uncompressed CD-quality audio would fit onto a single-layer BD-R disc?

I think Audio CD hols roughly 640MB and single layer BD 25GB so maybe like 45 or so full Audio CD and since 640MB at 1411KB/s or 640 *3/2 or 900ishx1000 /60 ish or 1.5ish hours or 90ish minutes but a bit less since we mult too much by about 10% so call it 80 minutes and then 45 of that is 3600minutes or 60 hours

and if you losslessly compress i think you can about double that

I really feel Bluray is the future of the music industry and I sure hope it catches like fire. 50GB may not be enough for film at times but it certainly is enough for the best music can offer.

and yet they seem to be aiming for 24kbps AAAAC compressed files I fear

I'd be curious to hear from anyone currently using consumer Blu-ray burning software who could weigh in on this.

I don't know whether the Blu-ray software even gives the option of burning an "audio disc". And if it does, then does it allow you to specify whether to use a particular Blu-ray spec such as the Blu-ray profile 3.0, or to just simply burn WAV files, etc.

I suppose, ideally, it would be nice to take advantage of the video capability of Blu-ray media to also include an on-screen menu for navigating the disc. And that would take up some of the space on the media. But if it's possible to burn 44.1/16 or 48/16 WAV files to a Blu-ray recordable, I can imagine having complete collections of a single composer on one (or a few, depending on the composer) disc.

Having used CD burning software, but not Blu-ray burning software, I'm really pretty clueless about all this.

Well I think you'd just burn it as a data disc to free up space from your hard drive or something. I'm not sure if there is such a thing as a CD format audio player than can read it off a blu-disc, never head of such a thing.

I just keep it all on my HD and play it off that it also means avoiding misreads and transport errors.

I guess there might be some blue audio players but you'd have to burn in that format. I've never tried. Not sure what programs support that.

Yes, or as a back up.

No, I mean using a Blu-ray drive to read the disc.

Yes, I also do this. This is generally more convenient than having to load optical media into a drive to hear something.

quietly introduced to the French beta-testers:

Companies are experimenting with it right now. Graphic Audio, a company which makes audio dramas of comics and original works, is going to be releasing a Blu-Ray of their new Spider-Man audio drama and it will have DTS-HD surround.

I want the music of the 60s, 70s and big band, classical, etc - to be released in as high a quality as possible! Can it be even done? Classical, and to some extent, Big Band, can be performed and released. How well was the other stuff recorded? Heck, the Beatles were mono!

Think of Wagner in 7.1 or better, off a BD audio!

Actually, it looks like that 'future' might already be here...?! cool.gif

A strategy developed by pureaudio (link) permits easy switching between several synched versions of the same recording on an audio-only Blu-ray disc . . . the RED GREEN BLUE and YELLOW buttons on the BD remote are used for selection in pureaudio's proprietary user interface software technology.

Some examples of what has been done with the pureaudio technology: SOUVENIR by TrondheimSolistene on the 2L label (link) and Portrait by Joseph Haydn on the MDG label (link) each offer significantly different (playback) versions of the same recordings (including with|without height speakers) . . . as the respective BD back covers show:

SOUVENIR by TrondheimSolistene...



Portrait by Joseph Haydn...

CREATOR: gd-jpeg v1.0 (using IJG JPEG v80), quality = 90

The L2 website indicates additional Auro 9.1 discs are in progress, and MDG appears to continue exploring Aurophonic 6.0 2+2+2 (aka 2-2-2) and Aurophonic 8.0 2222+ (aka 2222plus) configurations. Unfortunately the first Auro 9.1|10.1 home theater decoders are still rumored to appear only in late 2013|early 2014...?!

No extra points for confusing the names of the non-profit Pure Audio Group (link) and Universal Music's High Fidelity Pure Audio Group! eek.gifcool.gifbiggrin.gif

Listing of the approx 100 HFPA BD releases Universal Music Canada has scheduled for September 24, 2013 (link) . . . which also happens to be the Tuesday immediately preceding the start of CEDIA 2013 in Denver on September 25! biggrin.gif

Umm, no more than one or two of the very early Beatles recordings were mono. Weren't they really the pioneers of modern multi-multi-track stereo recording? Pretty much why they stopped touring and playing live I think. 'Course, i'm a Stones fan, so I may be wildly off base!

Actually they didn't record in stereo until Abbey Road. Everything before was mono and The Beatles liked that sound better. Engineers were in charge of converting the mono to stereo as soon as the band and George Martin were done with mixing. Supposedly The Beatles very rarely listened to the stereo versions once they were made.

Are you sure? I thought Revolver on (or maybe back to Help) were multitrack recordings with Abbey Road the (or their) first 8 track recording. Also how do you explain the DVD-A Love?

EDIT: Wikipedia
Quote:
...Many of the most famous recordings by The Beatles and The Rolling Stones were recorded on 4-track, and the engineers at London's Abbey Road Studios became particularly adept at the technique called "reduction mixes" in the UK and "bouncing down" in the United States, in which multiple tracks were recorded onto one 4-track machine and then mixed together and transferred (bounced down) to one track of a second 4-track machine. In this way, it was possible to record literally dozens of separate tracks and combine them into finished recordings of great complexity....

I'm not 100% sure of anything and I can't explain the DVD-A Love, but it does piss me off that there are no individual cd's like Rubber Soul etc. just this mishmash of songs. Don't get me wrong I like it just wish that since they went thru all the trouble maybe they could have done some albums in their entirety. Apologies to jontyrees he is mostly right. From what I read the first four records were mono everything else stereo that were mixed to mono and it was the mono mixes that the Beatles worked on with George Martin. Martin then oversaw the stereo mixes supposedly without The Beatles involvement. They, including Martin, thought the mono sound was closer to what they heard while recording in the studio. Abbey Road was the first album that was not mixed to mono and was allegedly the first time The Beatles worked from a stereo mix. The touring part I don't know about. I'd always heard it was Lennon who hated being on the road and could never understand why bands, especially The Stones, loved it so much. Now if someone could master the catalogue for Blu ray for mono and stereo I think the future of blu ray audio would look a lot better.
acebreathe's Avatar acebreathe 11:27 PM 10-10-2013
One last thing. I know Love was designed as the soundtrack for a Cirque de Soleil show which is why all the songs run into each other. It only came to be a DVD-A later when the potential for surround sound was there.

Let it Be(Get Back), and Yellow Submarine also have no mono versions, as well as a few singles from this time, like Ballad of John and Yoko.

No apologies required here! Like I said, I'm no Beatles expert. My older teenager just started listening to a lot of Beatles, which I never did, despite growing up in London in the 60's and 70's. I'll have to catch up! I also just found out that due to lightning damage, I'm not going to be able to listen to any BD-A or any other BD audio through my receiver. Of course, Black Friday is approaching......

Mostly true. Abbey road was recorded on a 16-track deck. The White Album on 8-track and everything prior to that on 3 or 4 track decks.
Actually I've read that the group was excited to hear the stereo version of The White Album and requested stereo versions of the vinyl.
I prefer the mono version of The White Album but that's just me.

Re: Love.
It is frustrating to hear the mash-ups because you want hear the entire song as it sounds so damn good.

Really? I never knew there were SACD releases of Breakfast In America, Back To Black and GRRR!. I don't know about some of the other titles. But I think you are incorrect in that "all" of the HFPA releases are from old SACD masters. As far as I know there are no accurate mastering credits for many of the HFPA releases.

I actually have the three discs you mention along with Stevie Wonder's Songs In the Key Of Life (and Nick Drake's Five Leaves Left on back order).

I have to say, I'm bemused as to why there is no standardised disc authoring method for this new High Fidelity Pure Audio disc format. For example....

Breakfast In America and Songs In The Key Of Life, have one continuous data stream on the disc. Like this: -






While Grrr! and Back To Black, have their tracks separated into individual data streams on the disc. Like this: -






Also, Back To Black offers a 'named' track list, while the other disc's offer only a 'number' track list.

Why is there no consistency here?!
