DSD vs PCM Explanation & Comparison
Here is an excellent article written by Barry Henderson, President of
iZ Technology Corp. who is the wizard behind the Radar 24 system. This is in response to a question about whether iZ Corp. plans to release a DSD recorder in the futu Audy There has been alot of discussion here at iZ lately about putting out a DSD machine. We even had a visit from Ayataki Nishio of Sony Japan, the man who invented DSD. We invited him to come to Vancouver a few months ago to meet with us and discuss the technical aspects of building a DSD machine. We may build one if we could get around some of the problems he pointed out to us, namely; 1) Advanced editing is not possible. The Pyramix system first converts the DSD files to PCM and then does the editing. If there is an advantage to DSD recording, then you may have lost it in the conversion. 2) Mixing is not possible. According to Sony, it is not ever possible to have a DSD mixer. AMS just released a digital mixer with DSD I/O. However the DSD immediately converts the DSD stream to PCM for internal use in the mixer and then converts it back again. We are concerned with having so many conversions that you may be introducing many artifacts into the audio. 3) The sample rate is not high enough. DSD is in its infant stage of development. The current "State of the Art" is 1 bit x 64fs (means 64 x 44.1 kHz sample rate) which is a data rate of 2.822 megabits per second per channel. RADAR currently has a maximum resolution of 24 bits x 216 kHz sample rate = 5.184 megabits per second per channel. The 64fs limitation is a Sony thing cause you need to use special Sony chips to make the recorder work which brings us to our 4th problem... 4) Development is very Sony dependant. Like it or not, its a PCM world and until that changes there will be very little demand for DSD. So it is hard to justify an R&D budget to do alot of very complex development only to still have significant problems remaining and a very small market. That said, we are looking at PCM to DSD file conversion. In other words we would record in RADAR PCM at 5 megabits per second in order to capture as many nuances of the audio as possible and then down sample it to the lower 2.822 megabit rate and save the files on another hard disk or even burn a DVD.

1) Advanced editing is not possible. The Pyramix system first converts the DSD
files to PCM and then does the editing. If there is an advantage to DSD recording, then you may have lost it in the conversion. Open to debate, since Pyramix maintains the 2.8 mbit data rate of the DSD stream and doesn't mangle its gentle filters. |

I think we have to consider the mind set that the statement: "If there is an advantage to DSD recording, then you may have lost it in the conversion." refers to. My understanding is that some people believe that there are some undefinable, immeasurable, currently unquantifiable *something(s)* that make DSD recordings sound better than traditional PCM with a similar or greater bitrate. I've certainly run into these people on Usenet and seen articles in other media that seem to say to the same basic thing(s). Since "gentle filters" actually exist, can be analyzed, quantified, and found to disagree with this belief about the alleged superior sound of DSD, it *can't* be what these people are talking about. BTW, one context in which I find these kinds of beliefs about the superiority of DSD is PCABX. I've suggested to DSD advocates that the output of a SACD player be digitized at 24/192, downsampled to 16/44, and the two be compared. The response is that re-quantizing DSD into any form of PCM destroys a significant sound quality advantage of DSD. Ironically, some of these same people go on for zillions of posts on Usenet about the improved sound quality of DSD recordings that are now known to have been made from 48 KHz PCM recordings but... |

My understanding is that some people believe that there are some undefinable, immeasurable, currently unquantifiable *something(s)* that make DSD recordings sound better than traditional PCM with a similar or greater bitrate. I reviewed the dbx 700 for Stereophile about 20 years ago. This unit used a delta-modulation system similar to DSD. I made at least one live recording with the mics feeding both the dbx 700 and my Nakamichi DMP-100 (a modified Sony PCM-F1). There was no question that dbx was superior to the Nakamichi, particularly in regard to high-frequency distortion. Brass instruments, in particular, were cleaner. Of course, this was a comparison between two particular products, both designed in an era when digital recording was undergoing significant refinement. It proves nothing about the ultimate subjective quality of either PCM or DSD. However, I've always had a prejudice toward bit-stream systems, simply because they're so crude. I bought a high-end Sony multi-channel SACD player last Christmas, and was pleasantly surprised to discover that SACDs were noticeably less hard-sounding and "colored" than CDs. "Unfortunately," my existing CDs showed a similar sonic improvement. So, if there really is a significant difference between SACD and CD, it might be due to nothing more than improved conversion. "One of these days" I'm going to get around to comparing the Sony's CD output to my Kinergetics DAC. The SACD player has an S/PDIF digital output for CDs, so it's possible to make instantaneous comparisons. |

The fact that DSD makes flattopping harder to do is a big deal, and will probably result in greatly improved sound quality. Not for any technical reasons, though, just for social ones. I have LPs that sound better than the CD, and CDs that sound better than the LPs. The guys in the mastering room have a lot more to do with the sound quality than the release format. This isn't going to change. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

We both know that, given a high-quality program source, a _single_ ReVox would not pass such a test. I've never heard a piece of electronics that was 100% transparent (though some come awfully close), and I doubt anyone has ever built a recorder (analog or digital) that is subjectively perfect. Do you know of any? Given the differences between PCM and DSD, it would not be surprising if one were more-accurate than the other -- or that they at least had different errors/colorations. |

Recorders aren't transparent at all, but they have long ago ceased to be the weak link in the chain. Given the differences between PCM and DSD, it would not be surprising if one were more-accurate than the other -- or that they at least had different errors/colorations. Absolutely. The question is whether these errors and colorations are really all that significant in light of the more severe errors present in speakers and microphones. I can't answer this, either, and I don't think anyone really can yet. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

The vast majority of the SACD's I bought are not remastered at all. The music sounds exactly the same as it has since I first heard it on vinyl, 10, 20, 30 years ago without the added noise. I still have most of the vinyl too. The couple of SACD's I have (one I sent back) that WERE obviously remastered sound like ass. DSD seems to be a clear reproduction of whatever you give it. So if you have an old analog master that sounds stunning, and LEAVE IT ALONE, that is what you hear. If you mess with it, the changes you make become even more obvious. The lesser systems, pcm, and especially MP3 kind of muddy the waters a little, so some of this stuff is less obvious, you can actually get away with a lot more futzing. |

So if you have an old analog master that sounds stunning, and LEAVE IT ALONE, that is what you hear. If you mess with it, the changes you make become even more obvious. The lesser systems, pcm, and especially MP3 kind of muddy the waters a little, so some of this stuff is less obvious, you can actually get away with a lot more futzing. |

DSD vs PCM Explanation & Comparison
About a year ago on RAHE Arnie was holding forth about the price of SACD
players being prohibitive, when challenged as to why he didn't just buy one and listen. He then said none were available under $200. When that price barrier was broken it was "under $150". All he ever does is propose we convert DSD to PCM and then be surprised when the signal gives a "no difference" under his abx testing to the same signal using the same PCM technology. It is an insult to our intelligence, frankly. "Rob Adelman" wrote in message ... William Sommerwerck wrote: I can't (always) read your mind and determine your intent, but... How can we take _anything_ you say seriously when you offer such a response...? Arny is afraid to listen to the format for fear he might actually agree that it does sound better. Easier to just avoid the possibility. b.t.w. a good player can now be had for 150 bucks! http://store.acousticsounds.com/store.cfm?Title_ID=12119&do=detail |

DSD vs PCM Explanation & Comparison
In response to the statement that you can't edit or mix DSD audio
files: Sadie has two DSD DAWs out now that purport to do exactly that. They are pretty straightforward guys, and there is no mention of them converting the DSD to PCM for editing or mixing. "The integrity of the 64fs DSD signal is fully maintained throughout the editing and signal processing operation." www.sadie.com Philip Perkins |

Harry, given your well-knokwn fascination with audio-related fiction, why don't you prove that claim with a quote from google? All he ever does is propose we convert DSD to PCM and then be surprised when the signal gives a "no difference" under his abx testing to the same signal using the same PCM technology. It is an insult to our intelligence, frankly. I don't believe I've ever insulted your intelligence, Harry. Or your veracity for that part. ;-) |

There's a reason why all the record companies are remastering the DSD layers - that's the only way they can bet on people hearing a difference. In fact you are quite wrong.

I still have most of the vinyl too. I strongly suspect that if I said the same thing about SACD and CD Rob, you'd probably condemn my hearing, my choice of player, and/or the rest of my audio system. The couple of SACD's I have (one I sent back) that WERE obviously remastered sound like ass. OK so what are you saying here, there's some magic something that makes *all* remastered SACDs sound like "ass"? I can't believe that the guys who remastered these things blew it 100% of the time. DSD seems to be a clear reproduction of whatever you give it. Of course I'm bound to agree with that. See the paragraph that I wrote and you quoted, Rob. That's what I meant - DSD can be reasonably be expected to provide sonically transparent reproduction. However, sonically transparent reproduction is happily NOT a feature that DSD ALONE can rightfully claim. So if you have an old analog master that sounds stunning, and LEAVE IT ALONE, that is what you hear. If you mess with it, the changes you make become even more obvious. Thing is, no way is LP record/playback *anything* like sonically transparent. I'm still waiting for *someone* to push my contribution to RAP 5 through the vinyl mill, and bring back an indistinguishable reproduction of it. Interestingly enough, the world is full of $59 CD Burners, $200 CD players and $39 CD ROM drives that can do this *trick* without a bit of trouble. The lesser systems, pcm, and especially MP3 kind of muddy the waters a little, so some of this stuff is less obvious, you can actually get away with a lot more futzing. How did MP3 creep into this discussion? Isn't the iTunes discussion in another thread? |

I would say, ok there is someone who disagrees. But currently, I am still waiting for ONE person who has heard a comparable recording on both to say the DSD does not sound better.

OK so what are you saying here, there's some magic something that makes *all* remastered SACDs sound like "ass"? I can't believe that the guys who remastered these things blew it 100% of the time. Well I have only run into two, so in my case 100% of the time was easy.. |
