Analog vs. digital segment on PBS


The show "Wired Science" on PBS this week has a good segment on analog vs. digital with a relatively quick blind panel test on analog vs. digital. I think they replay the show during the week if you can catch it. Nice to see some of the hobby getting some primetime attention, if PBS can be considered primetime of course! They have a couple recording engineers speaking about the merits of each and a blind listening test between a recording group (whose music they use for the test) and some unbiased recording engineers.
Also some info on frozen brains... either way it's a great show for general technology every week.

Interresting but the test was between masters in a studio, not between the end products of CD and LP, which is what the average and above average listener would be using respectively. :D
I too found this disappointing . . .

Perhaps the whole thing was faked and the band who claimed they could not tell were all paid to do so (or more likely the music was all from the good sounding analog).
I think the test was performed exactly as portrayed on TV. Electroid took the words out of my mouth as to how things were likely done for the "test."

Another good point. CD's are often a lot worse than studio masters due to the mastering process where they are compressed horribly to sound "hot" or "loud" (no dynamics left after this process and very prevalent with pop music).

ABSOLUTELY correct, right in the bulls eye.

Add to that, lots of playback equipment is not happy at 0 DB (maxed out all the time). The chip sets are designed to swing and take advantage of digitals great dynamic range.........then the engineers "loudness wars" the format and destroy it's advantage.
I have been a recording engineer for 24yrs. and use digital recording/Pro tools every day. So you might ask which I prefer, the answer good old 2" Analogue Tape. I have CD's, still listen to vinyl often and have never downloaded any music. If you could download full bandwidth files I might stop and think about it. I do prefer Analogue but these days it's usually more a matter of cost for most people. One reel of 2" tape $200-$250 and you get 15 minutes of record time and only 24 tracks of information. One album for a moderatly budgeted project 8 to 10 reels of tape. One 1 terabyte hard drive $400-$600 and depending on the system almost unlimited tracks. You could probably do at least 10 albums on the drive of that size. As for working in the digital domain it does not necessarily equate to being quicker or saving time. Also in my recent questioning, I find that alot of people just don't care, this is very unfortunate. The bottom line is I always try to record things to the highest possible level at my dispossal and within the clients budget. Just my thoughts on the matter. Just watched the PBS segment online, and it probably would have been better to have a nice sit down in a decent room, with some nice moderatly priced speakers to hear the differences.
Thank you Tousana. What great information in that story.

One of my good friends is a Grammy award winning classical musician, so I've been able to audition him live, versus digital, versus analog on several occasions.

During a recent visit to his home in New York I was able to compare several of his digital master tapes with the same material on Compact Disc.

The CD was a factory pressing, (not a special CDR which he also has), identical to ones released to the public. We listened to all on his high end system in a large dedicated sound room with his own personal equipment.

I am still shocked at how bad the CD's were compared to the master digital tape. The CD was a mere shadow of the original.

I have some analog safety's in my own personal collection (none are his work), with one that's absolutely a first generation (unmixed) master.

No doubt these best-of-best analog tapes are better than my LP's, even with my very high quality turntable and mere mid line tape playback machine.

Still, the difference between the two analog sounds is more dynamics and "you are there" rather than omission of quality and emotion.

In his system the analog was incredible as were some of the digital masters. BUT, the CD's as released to the public were just plan "nasty" compared to the original.

I would guess is the CD format itself is the problem. Do you agree or is it something that happens to the master when the record company gets done with it?

Opinion?
Albert, do you think the typical CD "quality" we experience is due to the disc itself. I believe I hear a difference when I listen to CD-Rs from standard Redbook CDs using the EAC software, but it is not double blind. Any thoughts?
