Re: MD: MD - MD dubbing?

2000-04-13 Thread Leon


If you read the MDCP FAQ... I think degradation, especially on modern
equipments, don't start occuring until at least the 5th generation. I've
done cassette--MD--MD (all analog connections), and the last generation
sounds fine. Just 1-2 generations between copies should go unnoticed even
with analog connections.

If I understand SCMS correctly, prerecorded MD -- optical cable -- blank
MD should be all right. First generation,

Norio Ohga, the (ex) Sony President who pushed for MD's creation, said
openly in publications that MD has sound degradations for political reasons
(or CD-R/RW music would've come out much earlier). But in your situation, it
should be almost indistinguishable.

 I've noticed HMV.com selling some of their selection MiniDisc format,
 which leads to an interesting question (either that or it just shows that
 I don't RTFM enough).  If I have an MD deck with a digital out and try
 record to my MZ-R50, I know I can't record digitally from an MD that is a
 copy of a CD.  Can I record from a store-bought MD to a blank MD without
 SCMS getting in my way?  Will there be a significant amount of
 degradation?
 
 What I mean by degradation is...  To record from CD - MD, I know that it
 takes uncompressed data from the CD, sends it to the down the wire in
 digital form, then the recorder compresses it with ATRAC, and stores it.
 To record from MD - MD, it uncompresses the ATRAC, sends it down the wire
 in digital form, then recompresses it when it hits the recorder.  I know
 that this would cause degradation, but does anyone know if this would
 cause unacceptable degradation in the sound quality?  Is it something that
 someone would even notice?

Yes you can. SCMS lets you make a digital copy of an original, but not a
copy of that copy. Your original in this case is the MD you bought in HMV,
so it will be quite happy with you copying it.

  Will there be a significant amount of
 degradation?

Define significant. There will be degredation, but how much and how
noticeable depends how sensitive your ears are and on what is in the music!
Some types of sound degrade more quickly than others but I would be
surprised if you notice it. It may even be less degradation than when you
record CDs.

 I know
 that this would cause degradation, but does anyone know if this would
 cause unacceptable degradation in the sound quality?

Again, define unacceptable. I think it's fine, some people wont even notice,
others will treat it like a criminal act if they can't hear an ant fart 200
miles away over the top of a heavy metal band.

  Is it something that
 someone would even notice?

Possibly, it depends on the music. Having noticed it, would it really bother
you? I've noticed very small differences between original CDs and copies
done digitally on the JB930, but it doesn't bother me because unless I
really listen for it I wouldn't have even noticed.

RE: MD: MD - MD dubbing?

2000-04-13 Thread Richard Lang


Re: MD - MD dubbing, my experience has actually been with burning onto MD a
copy of another MD which was digitally (optically) burned from a CD.  I've
done this a couple of times (original CD unavailable).

Obviously SCMS did it's job well (curse it!) and prevented digital recording
with a nice "impossible" message.  So we burned the copy by a reasonable
quality analog connection, my friends portable (MZR 30 I think) recording,
my JE 520 deck playing (from memory).  You'd think the result would be
awful.  But it wasn't/isn't.  it was a bit quieter than the original MD
copy, but sound quality wise I couldn't tell a difference when played back
on the same deck.  i still listent o those MDs.  One was mono, so sound
quality isn't such a big deal anyhow.

By contrast another time I experimented recording from my portable E 25 to
the JE 520.  The result wasn't awful, but it wasn't great either - I've
concluded this is because of the lack of a line out on the E25.

Now while we're on the subject of MD to MD dubbing, if you have two decks
with difference ATRAC, say one with ATRAC 4.5 and one with ATRAC R (or ATRAC
3 vs ATRAC 4.5), is there any consenus as to which should be recording and
which should be playing?  

My understanding is that even with digital connections, the music still gets
compressed on it's way "out" of the playing deck and compressed on it's way
"in" to the recording deck.  With analogue you are also dealing with A D/A
converter and an A/D converter.

My rule of thumb is that when dubbing betweem different machines, the best
machine should be playing, because that creates the best source for
recording.  Anyone? - Is this right?  Or doesn't it matter?
