More on DVD-Audio and SACD

Spock the Baptist writes "This article at CNN covers the drive of manufacturers to get the public to convert from the CD format to two relatively new formats, DVD-Audio, and Super Audio Compact Disk. The manufacturers cite the superior audio quality, and 3-dimensionality of the new formats' reproduction as the reasons for customers to embrace these formats. The article also goes on to say: "An added bonus for record companies and retailers, who are engaged in a battle against piracy, is that the relative complexity of DVD-Audios and SACDs makes them much harder to copy. At the same time, that might turn some consumers off the format.""

      I believe using headphones would defeat the purpose of the technology, unless of course you had a 5 channel headphone ring around your head.

      This statement needs some explaining. Seems like a way to push a solution for a problem that does not exist (or pure FUD). This can be done in pure digital already on a standard CD or simply encoded or enhanced prior to putting it on the disk. Adding fake reverb, chorus, and delays more often then not leads to garbage.

      The ONLY advantages I see for the consumer is the claim of increased storage per disk, and the 5.1 mode. Even then, headphones, your car, boom box etc will get no increase in quality out of this.

    If my CD's only encode say 20Hz to 20Khz having speakers that can produce say 10Hz to 30Khz does me no good. The inverse is also true, if my DVD-AUDIO cd has 10Hz to 30KHz and I have speakers that only do 30Hz to 10KHz WHO CARES.

We have fun shot pool and 2 hours later ate with the rest of the guests (there were like 40 of us there.) then we went upstairs to the "Fidelity Room" He had speakers that were like $2000 bucks a piece and had a self tuning equalizer setup (It was cool to see) and then we played a few select tracks off the CD. Sounded the same. Again we went and shot-the-shit so to speak for another hour as he prep his vinyl and the difference was night and day. The we listened to some tape recording of it (I think they were called DAT recordings) and that was damn good too! Both were far better than CDs. Anyways, a few days later after I had bought my home theater setup (Onkyo setup I bought while I was working at a Circuit City back in highschool, a 646 integrated amp with infinity speakers) and he brought over the Vinyl and Dat components. We listened to the CD, Record, and DAT tapes and guess what? They all sounded the same.

    Plain and simple it's like a car, the ability to top out at 300 mph is usless when the speed limit is 55. DVD-AUDIO and Super CDs are worthless unless the system they are played on can keep up.

    7. No TV is required to access the disk, track access is provided in a CD like fashion.
    8. All SACD's include text titles on the disc for track, artist, and album information.

    DVD-Audio:

    3. DVD-Audio does not have to include a stereo track. IMHO this is a bad thing.
    4. Linear PCM is the technology behind DVD-Audio. Max sample rates are 24bit/96khz for 5.1 and 24bit/192khz for stereo.
    5. LPCM is compressed and encrypted with MLP (Meridian Lossless Packaging). The compression is obviously lossless.
    6. Dolby Digital and DTS are lossy encoding methods akin to the beloved MP3.
    7. Some labels are including a "Macrovision Like" copy protection scheme on the DVD-A tracks.
    8. You can rip the DD or DTS side, but you cannot rip the MLP LPCM audio (yet). You may not even be able to record the analog audio if watermarking is included.
    9. The interface for a DVD-Audio disk may require a TV to navigate. There is no set structure allowing you to have easy access in a "CD Track" like nature. This is entirely up to the producer of the disk.

    Each format is a bit more expensive than current CD prices. Heck current CD prices are higher than they should be, but a new format should be expected to have higher prices initially.

Even if you think you have lead ears (i.e., noone can tell the difference between CD players, CD is good enough, etc.), I think many would be surprised to hear the difference when presented to them. The article mentions how even musicians think they're hearing complete sound, until they hear what's possible. Sound perception in humans is far from perfect and sound memory and recognition less so, but our hearing is still more acute than CD's allow.

    Given all that, the two competing formats are interesting especially from an engineering perspective (as I understand it). I'm definitely not expert on the formats, but here's my (half-baked) take on the current situation.

    DVD-A seems like an obvious winner for more multimedia capability and the appearance of backwards compatibility (its DVD after all, right?). Cool. However, DVD-A requires lots of electronics to process the signal including sophisticated D-to-A converters (a la the CD medium where they've been trying to perfect this D-to-A process for many years). This is the 16-bit... 18-bit... 20-bit progression you've probably heard of re: CD players. It's doable, but its kind of brute force from a pure engineering perspective, and from an audio perspective, it's less than ideal because the format guarantees a reasonably long signal path through all these converters and electronics.

    Enter Sony's SACD. SACD takes a radically simpler approach which puts the quality of the sound as the primary driver in the format. As I understand it, SACD format is based on an ongoing stream of bits (no words to chunk and convert). There's still work to be done, but the signal path is much shorter since the electronics are much simpler (vanilla compared to DVD sound processing). Some (many?) studios use SACD in the studio record and process music before down-converting it to CD format. So, SACD is about the music.

    Given those two issues, SACD could lead to phenomenally better sound even in cheaper units SACD players (than roughly equivalent DVD-A players) if (once?) volume sales and production arrive. Simpler, cheaper, and higher quality than CD (or DVD-A for the most part). So, I'm kind of taken with the SACD approach for the new audio standard. Perhaps DVD's themselves can upgrade (higher capacities for higher resolution movies) without worrying about DVD-A so much. Good sound for movies is nice, but at least get better than 640x480 resolution for the movies!

    So, here's one vote for a next generation audio format. And there are my (random, not entirely informed) two cents on the competing formats.

  28. Quality; deliberate degradation of CD track? by dpbsmith · · Score: 5, Interesting

    1) would love to read about a test where an IDENTICAL signal source was recorded in CD and SACD and compared, BLIND, by ordinary consumers. Is the difference really audible?

    2) More to the point, is there any way to STOP CD publishers from deliberately introducing degradation into the CD track in order to make the SACD sound better by comparison? Not that they would ever do such a thing, of course... but I'd like to see at least a truth-in-advertising disclosure if they did.

    Actually SACDs are an entirely different format that uses a digital bitstream (known as Direct Stream Digital or DSD) at a much higher frequency instead of Pulse Code Modulation (PCM) used by CDs and DVDs. Ideally this is a better digital storage format, but requires more space than the PCM used in CDs. By "better" I mean that the Analog to Digital (recording) followed by a conversion back to Analog (playing) will result in anolog waveforms that are closer to the original waveforms that were recorded as compared to PCM.

    This is not to say that DSD will really make much of a difference to the average user in terms of how their music sounds. Most people on basic stereo's will probably never heard the difference.

    For reference, Regular DVDs use the exact same PCM as CDs. DVD-A uses a higher bitrate, but it is still PCM.

    Personally I'm of the opinion that most mass produced CDs don't even stress the limit of potential "quality" of the CD format (PCM). I have a few extremely well recorded and phenomenal sounding CDs that indicate to me the potential of the CD format, but most CDs are mediocre recordings. Why should improving the format (DVDA or SACD) make a difference? If recording quality doesn't increase, it won't matter at all.

    I've heard the difference, and it's remarkable.

    My only friend who has a SACD player also has a $20K+ stereo (and I mean *stereo* -- no surround nonsense) with external amps, gold-tipped cables, etc... He played Brubeck's Take 5 on normal CD and on SACD for me. The change to the cymbals was unbelievable; it sounded like they were in the room.

    Granted, I don't know how much amp/speaker investment is required before you can hear the difference. But if the investment is low and the price of these fancy CD-replacements drops, I'd be interested. As for copy protection, anyone who thinks new formats will prevent copying is a fool.
