563.0. "digital remastering? ADD?" by NATASH::WEIGL (Turboferrets - racing for answers) Tue Dec 09 1986 12:31

    
    Can someone tell me/us what the "digital re-mastering" process does?
    Is it simply the process of converting the analog master to digital
    format?  Does that mean that the third "D" in "DDD" is redundant
    in that ANY CD is by definition in Digital format?  The first letter
    is the type of original source, the second is the "mastering" process,
    and the third is the final (Digital) format, right?  That must mean
    there's no such thing as a DDA compact disc?  It must be a record
    or a non-DAT tape, right?
    
    If digital remastering is anything other than the basic conversion
    of A->D, it's not clear what it is.  It seems to me that when the 
    analog master was made, that must still be the source for the 
    digital remaster, and that at best, you can only lose information 
    from that source.  Is there any other "value added" from this process?
    
    Lots of related questions here.  Sorry for the confusion.

563.1It really can help!!BOHR::CASSONEDom Cassone UPO1-3 DTN 296-4797Tue Dec 09 1986 13:3338
    The sequence of events from the actual playing of the music to the
    manufacture of the media. Here is a simplified view.
    
    First, the musicians play in a studio and each insturment and voice
    is typically recorded with (at least) its own microphone (except
    of course in the case of a synphony orchestra).  The output from
    each microphone is recorded on its own channel on the master tape.
    You now have a master tape with say 24 seperate tracks on it.  If
    the music was processed and put on the tape in digital fromat you
    get the first "D", else you get an "A" for the first letter.
    
    Now you have to take those 24 seperate inputs and mix them down
    to a 2 track stereo master. If the equipment used to perform that
    function is digital and the resultant tape is recorded digitaly
    you get a "D" in the middle place, else you get an "A".
    
    The last "D" is as you stated the actual media format.  Hence, for
    CD the last letter is always "D", and for LP it is always "A".
    
    Now to answer your question, if the original studio recording was
    made in analog format, and they took that tape and "Digitaly
    Re-Mastered" it to the 2 track master used to make the CD, you get
    ADD.  What they mean is that the 2 track master that they had been
    using to make the final media (LP, Casette) was an analog master,
    but they went back and made another one in digital format before
    they manufactured the CD.
    
    This can lead to improved sound even though the 24 track (in my
    example) master is of analog format.  This is because each time
    you transcribe the data you add the problem, that is you get more
    tape noise etc.  And since you can not go back to the studio and
    re-record most of the music (it would be real tough to do "I Want
    to Hold Your Hand" again) Digital Re-Mastering is the best you
    can get.
    
    Does this help?

563.2The Mixer gets another chanceSKYLAB::FISHERBurns Fisher 381-1466, ZKO1-1/D42Tue Dec 09 1986 14:175
    I suppose since digitally remastering is really a remixing, that
    the results could sound significantly different from the original
    AAA due to different decisions by the mixer, huh?

563.3Let's hope it doesn't go to his headBOHR::CASSONEDom Cassone UPO1-3 DTN 296-4797Tue Dec 09 1986 14:284
    Hi Burns!!!
    
    I suspose that's true, but one hopes that the result is not too
    much different from the sounds that we have grown to love!!
563.4Sometimes they can't leave well enough alone....BETHE::LICEA_KANETue Dec 09 1986 14:3320
    
    Yup, that's right.  Nothing says that two people taking the same
    masters are going to mix them down the same way.
    
    I've wondered about what it would be called if the original master
    was a two track digital.  D-D?  Or would it be -DD?  I'm thinking
    of the digital equivalent of direct to disk (direct to disc?).
    
    
    And yet another controversy.  Some "labels" are re-recording tracks
    since the original masters are either deteriorating or just plain
    bad.
    
    Well, you can either re-record the track faithfully, or maybe you
    decide to update it a little bit.  You know, give an old Elvis
    song a little more contemporary feel.
    
    Yeesh.  Colorized CDs.

    Shefield Labs CD's ( or most of them) are two track sources and
    then digitally mastered, hence missing the middle D.
     
563.6dreaming?BISTRO::HEINHein van den Heuvel, Valbonne.Wed Dec 10 1986 04:134
    Isn't the mix information written back to the umpteen track source
    media and thus available as input for the re-mastering process?
    
                                  Hein.

	Yup, like in the case of Sticky Fingers to roll off the bass 15 db.

563.8Mixers are artists tooSKYLAB::FISHERBurns Fisher 381-1466, ZKO1-1/D42Mon Dec 22 1986 13:0410
    I meant my question about the remastering not to be a "suspicious
    question" (i.e. trying to blame the new mixers for screwing up).
    Surely a mixer is an artist just as much as the performers.  When
    Deatht�ngue does "Breaking Up is Hard to Do", do we say that they
    have screwed up if it does not sound exactly like Neal Sedaka? 
    
    (Hmmm this is beginning to sound suspiciously like a debate about
    coloring "The Maltese Falcon").
