You said that doing any filtering in the digital domain would skew the results.
No, I said filtering would skew it. Any filtering will mean that the output is highly different from the output. That's the whole POINT of a filter!!! Surely you must see this?

But that is the second part of the test. If we are looking to see if the color of digital is objectionable (to some) we do need to do some filtering. Do you record without any filtering?
But that have nothing to do with "accurate", which is what we are discussing now.

As for misconceptions that is what I was thinking about you. :) My background is as a system engineer. Most of my programming has been in assembly in embedded systems. I've designed a number of data sampeling systems that work at audio frequencies up to video frequencies. Currently I've designed and operate a beowulf cluster of 128 nodes with 50 TB of data online. We have a realtime data collection network that measures the parameters of the Columbia River and the near Ocean shelf out to about 30 miles. This is analog to digital and process the data and compair to the model results. Of course our sample rate is much less than audio and the precision of hte data is much less than 16 bits. I do not say that I am an digital audio engineer but I am a research engineer with 35 years experience in digital and analog design.
And still you seem to know so little.
Please let know about those misconceptions you suspect that I have.
But, please, don't you think I point them out as soon as I figure out what they are? Since you obviously think I have misconceptions, maybe you can tell me?

Honestly, man, this discussion is getting to be seriously stupid. You have not come with a single relevant argument about anything. You claim digital is not more accurate, than analog, and you device a test for testing this like nobody else has measured the errors digital equipment introduce already, and then it turns out that you don't even understand the difference between accuracy and subjective taste in filter-colour. Puhleeze...

I did not say you called me anything. I am stating how these threads end up. I talked with Steve directly like I talk to Fletcher and a few dozen other engineers directly. My point is that the last stop for virtually all professional commercial relaesed recordings (other than CD) is the digital workstation for editing and album ordering. Therefore, the recordings that say "AAD" really are "ADD" even though they recorded the basic tracks on an analog machine. The studios use analog machines these days for the effect that they have on drums, bass and guitars. They can, and do, record all digital when the song demands it. There are even talanted engineers out there that do all digital recording and make it sound analog. Listen to these engineers digital recordings and you will see that the "digital bashing" is based on equipment made long ago. The "analog sound" has been what our generation (or anyone listening to pre-digital music) is used to. The new engineers will never see analog and rightly so. Analog is pretty much done in both pro and consumer markets. I guess according to all the analog only guys, when the last analog machine dies there should be no more music.


Lastly, all audio engineering schools have dumped their analog everything. They don't teach on anything but Pro-Tools and analog/digital consoles. So, digital is here to stay and it won't matter to you or anyone on here that refuses to embrace it. This discussion is meaningless as well. The world is digital and will stay that way. The engineering going on to make the digital systems sound more analog is under way in a fast and futile manner. These digital guys will catch up and make analog vs. digital a moot point period.


The future of analog will be (and currently is becoming) a buisiness of "boutique" studios that will offer analog recording for the "retro" artists and charge accordingly. Right now, if you look at the audio broker pages, you will see that the pro used machine market is totally glutted with used machines. These machines are going to home studio owners and some pros for parts/use. But there are way too many for sale with no buyers. Exactly the opposite with the consumer Tascams and the like. I will say that in a few years, a pro machine will be cheaper than a Tascam 16 track.

Actually a good post and everything makes sense and well written.

Now, as for today (not in the future), in respect to the question (why still analog?) , I have couple practical questions here:

The studios use analog machines these days for the effect that they have on drums, bass and guitars. They can, and do, record all digital when the song demands it. There are even talanted engineers out there that do all digital recording and make it sound analog.

So, does this mean, that with today's REAL high end professional digital-only recording system, let's say, ProTools, a highly educated and talented person in professional studio can achive the same result as an uneducated talentless (in respect to engineering) rocker with, let's say, MSR-16 in his garage?

Listen to these engineers digital recordings and you will see that the "digital bashing" is based on equipment made long ago.

Would this mean, that huge majority of the literature and reviews, written by these engineers about, let's say about tascam DA-30(mkII), audiomedia-III, Akai (DR-4/6/16), Marantz CDR-620 at the time as these products were poping-out were 'softly say', - missleading.?
Maybe they should of been stating it more clear back then, by pointing out, that "What we are saying about these products is not really what it is , but rather what it maybe will be like in a few years ahead, while at the moment - this is what we got - yada yada, buy it and use it on your own risk, but do not dump your trusted machines yet.

btw, I've picked these old low end digital recording machines models also because I have these suckers (seating right here in the rack as evedence of my ignorance), and I had a chance (sent by holly spirit, I guess ;) ) to compare them to some REAL! REAL old R-t-R machines. I am not sharing the result of comparing - Enough of laughing at me ;) , I'll keep it for myself.
And I also have 'evedence' on paper (written statements) about what have been said and how it was presented by Real Pros - "people who knows", as I used to be a subscriber of publications like Recording, Mix magazines etc.... I keep them - I too need something for good laugh from time to time.

(IMPORTANT!!!!!!!!!!! I have absolutely NOTHING against professional studio engineers and professionals who's job is related to recording, musical instruments and recording equipment. I know personally many guys who record for living and guys who sell instruments and equipment for living. On the personal level - cool, friendly, humbly knowledgeable DUDEs :cool: But don't just take anything and everything that comes with prefix "Pro" as 'a word from Bible'. These guys are the same people as you are, and don't forget, they have work to do, they do not keep their studio for personal pleasures (meaning I do what I want when I want the way I feel if I feel like).... they have to satisfy the Client and stay in business. And this business isn't easy. If, let's say, between forces of record-industry and the consumer's sense of fashion all that is needed at the moment and being asked for is just crappy ugly and bangy noise, then that's what professional studios are forced to produced, and they will do just that or they will have to disappear, and then, you can guess, - the studers will be covered and rolled outa' picture. So when you see NO studers in the big-boys's rooms on the cover of the MIX, The question is: "Would this mean anything to YOU as a musician and self home-studio based producer?"

then, kinda keep thinking, in general, DOES The Fact, that studers and protools are great and there is a hot shots somewhere out-there who seats in between of both and tells you how great they are in combination, do anything to you at all? Does it have any practical meaning? Yeah, that's great, so what?

SO WHAT!!!!!!!!?

Sigh,

Why the insults? I've stated my positions and at your request given you my background. You toss an insult back to me and offer nothing to support your assertions.

Show me the data. Show the list the data. And if you cannot produce data then do not present it as fact.

Regards
 
we need a Madman here

Sorry, guys, I don't know...hah, it's just came to my mind: "What would Madman Lee Scratch Perry had to say if he'd got into this 'discussion'?"
Yeah, I know, maybe nothing funny here, but if you have heard/read his 'remarks' about music production technicalities, then you maybe find it pretty funny just imagining what his replies might sound like.
Maybe, actually he is a perfect Mind to resolve this once and FOREVER! :D

I'm not sure you have done that either. :confused: Yes, you gave me your background, for some reason that is way beyond me. As a long time professional computer programmer and digital engoneer I am almost amazingly unimpressed.

I don't give a shit about your CV. I care about arguments and facts. And claiming that you can measure the accuracy of digital as compared to analog by running a signal through a digital filter and comparing with the insignal is neither a position statement, an argument or sensible. It is just plain wrong, on many, many levels at once.

If you find this to be an insult, then so be it. It is however still true.

OK, Let's analyze this statement. :D


regebro said:

Little is relative.

regebro said:

Compared to whom or what?

May this line echo infinately in your soul regebro. The law of Karma is at work here. :p

The compairision has never been digital vs analog. The compairison is digital vs live paralleled with analog vs live.

The observation drawn is that people tend to like the way analog reproduces live better than the way digital reproduces live. Therefore analog tends to still exist (the question was why analog not which is better analog or digital)

a is to b as c is to b but not a is to c (where a is alalog b is live and c is digital)

I don't make a claim as to the accuracy of digital vs analog I did say that you can measure the accuracy of digital in realtime by summing the transfer function of a digital mixer with live in the test I proposed.

You have assured me that such a test would be meaningless because there would be no artifacts audable. But again show me the data. Perhaps the results would be the most inaudable imanaginable and I would eat my hat and say WOW digital is accurate. Or perhaps the results would be mostly silence with moments of nerve jarring noise. Till we do the test we do not know.


As for my CV I've not given that. Perhaps you recall saying "I have the feeling (but I'm not sure) that your view is so full of misconceptions about this issue that we tend to talk over each others heads." THis is your expression that my "view" was flawed. So in defense of my view I expressed some of the things that I have done that lead up to that view.

Great, you are a programmer. What languages do you program in and on what systems? I am interested, perhaps we have some commonality there.

Hey, regebro, what do digital engineers do exactly? :confused:

Also, how an engineer can get digitized to become a digital one, if desired? Is there some special facility somewhere? Gotta do some search on it, I guess... :rolleyes:

Ahhhh... I see. Hmmmm, I guess my fantasies fooled me again. No place and no way to get digitized on this stinkin' planet. :(

You seem to confuse "good" and "accurate".

You have assured me that such a test would be meaningless because there would be no artifacts audable.
I never said any such thing.

Till we do the test we do not know.
I know. You can look up the data on the internet, and both high-end digital and high-end analog have similar numbers when it comes to just mixers, whoch are stupidly low and competely inaudible, yes. This is not magic or bleeding edge or new research. This is all well known facts. I don't understand why we are still discussing this, it's so completely daft. I'm stopping now.

The problem with digital does NOT lie in that it destroys the sound, or skips information or is less accurate that analog. End of discussion. If you want to discuss something, discuss something that hasn't need beaten to death over and over and over again.


btw, I nowadays program only in Python, except at gunpoint.

So Lennart, What is the problem with digital?

Regards,

PS we tend to use Perl for most of our scripting with a little python thrown in. Doing modeling that can take more than a week on our cluster to run we tend to use Fortran (yea I know but it does do math). I do truley love assembly. Nothing like being in the heart of the machine. I've created a few microcode loops before and found writing microcode interesting too.
 
Okay then. Everyone put your hands at your sides and quietly back out of the room. ;)

Hands at your sides? Oh no... I know what you're trying get started here -- River Dance. We're not going to fall for that. ;)
