"Gus had hinted to me that he had a significant announcement just before the panel session started. When it came his turn, he startled me by saying that there was little known "DSD Disc" specification from Sony that would allow stereo DSD Discs to be produced without going through the SACD authoring/mastering system! Any Sony PS3 would play them as pure stereo DSD via the analog left/right RCA outputs using the PS3 RCA adapter! DSD-equipped Sony Vaios, too! Which meant that there was already an installed base of tens of millions of DSD Disc players! Not only that, but DSD Disc files were stored as ISO image files, and could be transported over the Internet (!!) and burned to DVD on any computer for playback on a local PS3(!!!) Apparently this has been a subset specification of the PS3 all along, but—unbelievably—Sony hasn't publicized it to either the industry or the general public. I am sorely… sorely, sorely...tempted to weld "completely clueless" to "Sony," but no, I'll resist.
Gus Skinas of the Super Audio Center: this was a man with some significant news….
Amazing!
After all these years of DSD being presented as a locked-down, non-transportable format and specification, incapable of downloading/burning, we were suddenly being told that there was a way to get stereo DSD punted about the planet in a very open-source friendly manner.
Sonoma workstations/toolsets or their equivalent are not outrageously expensive, but they do cost enough to keep many labels from acquiring them. And the cost of having DSD masters from various DSD recording systems (e.g., Sonoma, dCS, Tascam, Genex, Pyramix, and Korg) produced can be likewise daunting in these days of tight budgets and general cluelessness in the music biz. It's definitely overkill for most of the Indies, who might be mightily impressed by the musical quality of DSD (if they've heard it… most have not), but can only afford the cheap tools of PCM, with all the sonic limitations of lower resolution PCM. But with DSD Disc, an Indie could easily roll into, say, a Korg MR-1000, record DSD at either 5.6 mHz or 2.8224 mHz, and then go directly to stereo DSD on DSD Disc format, or distribute them via * on the Internet. Very spiffy!
A fresco of the Korg MR-1000 DSD recorder with integrated hard disk, supporting either 2.8224 mHz or 5.6 mHz sampling rates: very compact… DSD on the go! MA Recordings has been using the MR-1000 for its recordings recently, with spectacular results.
Needless to say, DSD Disc had caused a bit of a stir among the panelists. DSD in ISO, transportable over the Internet… supreme audio quality, with the ability to be handled on computers? This is really something. Will it develop legs in the marketplace? Good question. Charles Hansen said that while it would not be trivial, it would be possible to re-program the Ayre DAC to handle DSD, since DSD capability is embedded in its chipset. Once that was done, a simple firmware update would deploy the improvement. This would liberate audiophiles from their PS3s, and allow them to process stereo DSD via an asynch USB pipeline with a master clock, ensuring near-zero (perhaps actual zero?) jitter, instead of having to use AES/EBU or ST glass I/O.
And that, chilluns, would be quite the accomplishment.
Yep, it's real: the sample DSD Disc of David Elias' The Window… plays just fine on the PS3! This could allow DSD to enter the world of open standards and Internet/DVD burnable, without a doubt.
By the way: Gus gave me a sample DSD Disc…nothing less than David Elias' brilliant recording, The Window. I took it home and tried it right out on my PS3; it worked like a charm! All that you have to do is load the disc, go to the Music menu, and you'll see an icon labeled "DSD Disc"; click on it, and the tracks will load. Click on the first track, and away they go. Note: even PS3s that don't support SACD playback (like the one I have) WILL play DSD Discs.
And here's another interesting fact, one that Gus didn't know until I told him: My PS3 output the DSD Disc via HDMI as well as the analog outputs. When Gus and I talked about this, he was surprised that the HDMI audio output was working with the DSD Disc, but was sure that the output was DSD converted to PCM. HDMI does not necessarily convert DSD to PCM…there are several player/processor tandems that do handle bitstream via HDMI… but I'd agree with Gus that the PS3 is not doing this. Since there's no problem using the analog stereo RCAs to get DSD quality…simple will be better at this point when dealing with PS3s…we can go with it.
There are already some folks exploring DSD Disc support, including Ayre Acoustics, Oppo Digital, MA Recordings, and the Super Audio Center. Korg ought to become aware of this, as well. I've already received samples of DSD Discs from Todd Garfinkle of MA Recordings that sound absolutely terrific, so there is encouraging real world progress here. Todd may even be willing to sell you a sample DSD Disc if you bug him… of course, he still has a few copies of his stellar SACD sampler, MA on SA, which you simply must get if you love SACD. Check out his website at
http://www.marecordings.com. I'll keep you informed about DSD Disc as I know more… stay tuned."
