24 bits of what?
I saw in stereophile they are releaing some old stones stuff in
http://www.stereophile.com/content/h...ez-downloads-= rolling-stones stuff "at 176kHz/24-bit and 88kHz/24-bit.". Isn't this a greater resolution then the analog equipment used to create and then transfer to digital these recordings which the article describes as "For the analog to digital transfers, vintage reel-to-reel tape machines were utilized=97a modified Ampex 351 with original tube electronics (full track mono and two track stereo) and an Ampex ATR-102 modified with Aria Discrete Class-A Electronics (full track mono and two track stereo). A Sonoma DSD digital audio workstation was the chosen high resolution format and Meitner Design ADC8 and DAC8 MKlV converters were used for the conversion process." Is this just another milk the consumer exercise? |

There's certainly nothing new about record labels remastering old material. Is there something wrong with allowing Stones fans to buy their favorite recordings in the highest quality possible? Some people think such remasterings - which sometimes are only subtly different than the original - are pointless. But that's a subjective judgment. That doesn't mean offering them for sale is a "milk the consumer exercise." If you don't want the remastered recordings, don't buy them. |

Is this just another milk the consumer exercise? No, the consumer might be reassured that greater than usual care was taken with the transfers. It might also be convenient to download to server instead of ripping discs. OTOH, I have a relatively recent singles two-cd set I think was based on the dsd masters and it sounds great in casual listening. Stephen |

Is this just another milk the consumer exercise? Not exactly. Even though there is not much point it the super high-res format, Bob Ludwig did a stellar job of the remastering back in 2002. Andrew. |

Isn't this a greater resolution then the analog equipment used to create and then transfer to digital these recordings which the article describes as Not only greater resolution, but also far greater bandwidth. "For the analog to digital transfers, vintage reel-to-reel tape machines were utilized a modified Ampex 351 with original tube electronics (full track mono and two track stereo) and an Ampex ATR-102 modified with Aria Discrete Class-A Electronics (full track mono and two track stereo). The ATR 102 was quite a piece of work. The 351, not so much. A Sonoma DSD digital audio workstation was the chosen high resolution format and Meitner Design ADC8 and DAC8 MKlV converters were used for the conversion process." They could have done the transfer with the audio interface on the motherboard of a fairly new PC with sonically equivalent results. Is this just another milk the consumer exercise? The mastering of some old Rolling Stones recordings was pretty nasty. The super-science fair transfer equipment is overkill, of course. A proper remastering job might be worth something to listeners. |

Is this just another milk the consumer exercise? Not really. If you buy the premise that CD resolution is insufficient to accurately represent music (and many do including well known recoding and mastering engineers), then quantizing these analog master tapes at "high-resolution" formats makes plenty of sense. I've been sitting here trying to come up with an analogy that will adequately explain the rationalle behind this practice. The only one I can come up with is pretty lame, but it might get the idea across. High-Definition TV movie channels show both old and newer Hollywood films in 1080 X 1920. Occasionally, they show an old black-and-white non-widescreen film from the 1950's or even the 1940's in HD. One would think that this was overkill. Part of the appeal of HD is the larger color palette it affords over regular TV as well as the ability to show wide-screen films without the radical letter-boxing required to show these films on a regular NTSC television. But the thing is that these old monochrome films look magnificent in HD! There's a look to the film that the extra resolution heightens, a look that regular TV never could elicit from these films. Recently, I saw a gorgeous print of Carol Reed's magnum opus, "The Third Man" (With Orson Welles and Joseph Cotton). The stark black and white photography of Vienna after WWII never looked this good before! The night scenes with the wet cobblestone streets and harsh lighting looked as they must have looked in a first-run theater back in '49. So, what looks like overkill, turns out to serve the program material very well, better than lower resolutions transfers ever have. Now Audio is different, I realize that, and the difference between high-definition TV and regular TV is not controversial as is the difference between regular CD and high-resolution audio formats. And there's something else going on here too. It's the idea that many have that since analog tape is continuous and digital is sampled, that the more samples one takes per sampling rate interval, the more of that continuous analog signal that is captured digitally. Of course, the reality is that digital sampling doesn't work like that and the people who believe that high bit rate and high sampling rates means that more of continuous nature of an analog recording is captured, are operating under a misconception. Higher bit rate and higher sampling rate does have it's advantages, but they're not what they would seem to the casual observer, and it's not really clear that these improvements over CD resolution are even audible. |

Movies shot on film have a MUCH higher resolution than even Blu-Ray. Films are scanned at between 2 and 8 thousand lines horizontally. Blu-Ray High-Def video has a resolution of 1920 x 1080, and "regular" HD DVD-video is 720x480 (I think). Here's a link trying to estimate the pixel-resolution-equivalent of 35mm film (he's a still photographer, but the majority of movies are shot on 35mm or greater): http://www.kenrockwell.com/tech/film-resolution.htm The estimate is 175 megapixels. That's around 13 thousand pixels by 13 thousand pixels. About a hundred and sixty nine times the resolution of the highest commercial video system! Now, a crucial question, one obviously paralleling the isues about audio sampling and so forth, is how much of that resolution is needed to replicate the visual experience of the original film (i.e. beyond what pixel density does a viewer not notice a difference). I don't know. And one thing to keep in mind is that a movie (the original film print) is meant to be displayed on a big screen, although I am usually far enough away that I'm effectively farther way from the screen than I am from my HDTV at home (in terms of visual angle). But the thing is that these old monochrome films look magnificent : in HD! There's a look to the film that the extra resolution heightens, a look : that regular TV never could elicit from these films. Yes. But it should, since the HD format and the standard format differ by a factor of four, roughly, and HD is far below our abolity to see detail. So a SD version (broadcast, DVD scan) of an old movie misses even more data than a HD one. : And there's something else going on here too. It's the idea that many have : that since analog tape is continuous and digital is sampled, that the more : samples one takes per sampling rate interval, the more of that continuous : analog signal that is captured digitally.

Right. And that's where our visual and auditory systems seem to diverge: we have extremely acute vision, and I don't know whether anyone has done the sorts of tests on resolution and visual acuity that have been done on audio resolution.

Not really. If you buy the premise that CD resolution is insufficient to accurately represent music Buying this premise requires considerable disregard or ignorance of the recent findings of science. (and many do including well known recoding and mastering engineers), Being famous doesn't mean being smart. Pehaps we're talking about the Lindsey Lohans of audio. ;-) then quantizing these analog master tapes at "high-resolution" formats makes plenty of sense. Ignorance + notoriety = what? I've been sitting here trying to come up with an analogy that will adequately explain the rationalle behind this practice. How about throwing good bits after bad? ;-) The only one I can come up with is pretty lame, but it might get the idea across. High-Definition TV movie channels show both old and newer Hollywood films in 1080 X 1920. Occasionally, they show an old black-and-white non-widescreen film from the 1950's or even the 1940's in HD. One would think that this was overkill. It all depends on the source material. AFAIK most of what is known about making high resolution film and optics at any price was known back then. Look at the Leicas of the day. The counterpoint is that high resolution optics are merciless on less-than-perfect skin and sets. I suspect that that the resolution that was delivered back in the 1930s and 1940s were already the consequence of what shall we call them, artistic choices? Part of the appeal of HD is the larger color palette it affords over regular TV I'm told by video experts that there is no such thing. After all, analog TV was well, analog. Wasn't the resolution of colors well, infinite? ;-) It takes more than digtial to increase the size of the RGB pallette. It is what it is. As far as color pallette goes, CRT-based displays are still the gold standard, my videophile friends tell me. Most HDTV cameras sacrifice color quality and low light performance to cobble up the huge number of pixels and motion video. as well as the ability to show wide-screen films without the radical letter-boxing required to show these films on a regular NTSC television. That can't be denied but only a tiny minority of films were color and/or wide screen in the 30s and 40s. Even in the 50s. But the thing is that these old monochrome films look magnificent in HD! Some do. Some look like mud even in SD. There's a look to the film that the extra resolution heightens, a look that regular TV never could elicit from these films. Its all those pixels. Recently, I saw a gorgeous print of Carol Reed's magnum opus, "The Third Man" (With Orson Welles and Joseph Cotton). The stark black and white photography of Vienna after WWII never looked this good before! The night scenes with the wet cobblestone streets and harsh lighting looked as they must have looked in a first-run theater back in '49. So, what looks like overkill, turns out to serve the program material very well, better than lower resolutions transfers ever have. Orson Welles was well known for his technical budgets. Now Audio is different, I realize that, and the difference between high-definition TV and regular TV is not controversial as is the difference between regular CD and high-resolution audio formats. I have yet to see a rebuttal for this document: http://hlloyge.hl.funpic.de/wp-conte...p-inserted.pdf And there's something else going on here too. It's the idea that many have that since analog tape is continuous and digital is sampled, that the more samples one takes per sampling rate interval, the more of that continuous analog signal that is captured digitally. That shows a lack of understanding of analog tape. Analog tape is quantized at the level of the individual granules of magnetic media, which are actually pretty large. Of course, the reality is that digital sampling doesn't work like that and the people who believe that high bit rate and high sampling rates means that more of continuous nature of an analog recording is captured, are operating under a misconception. That shows a lack of understanding of Shannons Information Theory which has gone unrebutted for over 50 years. There is no such thing as a "continuous nature of an analog recording" because the dynamic range of rela world analog media is crap compared to modern digital. Dynamic Range = Resolution. Period. If you want to properly digitize a LP or an analog tape and get everything audible on it and then some, the on-board sound card for a cheap but modern PC will suffice. Higher bit rate and higher sampling rate does have it's advantages, Still no rebuttal for this document: http://hlloyge.hl.funpic.de/wp-conte...p-inserted.pdf but they're not what they would seem to the casual observer, and it's not really clear that these improvements over CD resolution are even audible. Its less than unclear - it has never been reliably been shown that anything has more audible resolution than the CD format at its best. Remember that the reference shown above demonstrated its point beyond reproach, and used a brain dead implementation of 16/44 to do it. |
