MD: Chassis MiniDisc decks

2000-03-15 Thread Simon Mackay


 === The original message was multipart MIME===
 === All non-text parts (attachments) have been removed ===

As I have looked at various MiniDisc decks that have been on the market, I
have noticed that a lot of Sony decks and some bookshelf systems have very
similar layouts -- just a bit of internal improvements (ATRAC, DAC, extra
facilities) and some slight cosmetic changes such as slightly-different MD
slot escutcheons.

For example the JE530 looks very like its predecessor (the '520), except for
a newer slot escutcheon and there are a few internal improvements to the
firmware for abilities like Control A1 and variable pitch playback as well
as some slight improvements to the ATRAC and analogue interface gateway
circuitry.

This still can be of benefit if older models were broken beyond repair and
it was possible to use most parts from the newer models for these units.

With regards,

Simon Mackay

2000-03-15 Thread Andrew Hobgood


 Which brings me back around to the original point that implementing real
 time ATRAC in software on today's desktop is not going to happen.

Well, I think that there's a small qualifier here.  I've been watching this
thread for a long time now, keeping my trap shut.  What it comes down to is
that while ATRAC *could* be implemented in realtime (if not now, then in the
near future), but that the complexity of the algorithm makes it a stupid 
decision.  It'd be cheaper to just make a small ATRAC board that carries 
the $5 ASIC on-board, or some other embedded solution.  

It's the same argument as any other form of emulation -- sure, you *can*
run your Playstation games on a computer with Bleem or such, but will that
make people stop buying Playstations?  No.  The hardware inside a Playstation
is designed for a small niche, and ATRAC chips are the same way.  It's does 
only one thing, but it's very, very good at it.  A general-purpose computer
is better utilized for more generalized tasks.

 Is this from experience or some other reason? I have a couple of flights
 this week, both by Airbusses (A320/319) and would like to listen to my
 MDs or at least take the opportunity to title my tracks.

I've listened to my MD on Northwest Airlines A319 flights with no problems.

They're just limited during takeoff and landing.

MD: mz-r30 in X-Files

2000-03-15 Thread Jeanmougin


You're right. The man uses a mz-r30 to record the conversation from the
distance. Using a MD is cool but the best is the type of microphone
employed to do it: it is a laser microphone. Very compact, stealth, no
EM or RF emissions. Detectable only with a laser detector.

MD: Finally! 80 min MD's in Australia

2000-03-15 Thread Tony Antoniou


Just picked up 3 2-pack's from work. TDK MD-XG 80 in a 2 pack with a bonus 6
disc carrying case (opens like a book, stores 6 discs without their
sleeves). The (totally transparent) sleeves themselves seem to open up like
a book. The MD still slides in and out as per usual. But the reason behind
it opening is so that you can write on the backing/carrier sheet for the
stickers. Once you've used the stickers, the other side of the carrier
actually has lines on it like your cassette (YEECH!) slips, so that way you
can write up your track list for the sleeve itself rather than sticking
labels on it. Not a bad idea that. Not bad at all.

You can also buy them individually without the bonus case, but in my
situation, where I purchase them at below retail as part of the employee
purchase scheme, it was 20c cheaper to go for the 2-pack. The MD-XG 74's are
actually cheaper for me to buy individually rather than in their 2-pack form
(which has no included bonus).

Now I can finally record Dream Theater's "Metropolis 2" in its entire 77:14
length! 3#-)

There have been several non-professional software programs made in my
area by some people who were able to see how the chip worked and was able
to get the code from it (my friends dad worked at a place that had a chip
reader).

Not that great, but realtime.

 Even if a high-speed ATRAC chip is used as opposed to software ATRAC, I
 think the encoder would be better off at the PC end as this allows more
 utilisation of the limited bandwidth USB ports.

Well, I'll just give my standard response to this sort of argument -- USB 
is designed for peripherals, not for media storage or transfer, IMHO.  If 
I'm going to be doing data storage or retrieval, I'd be using SCSI.  

Honestly, making some kind of hardware-based solution makes the most sense,
but if you're trying to save bandwidth on an already-CPU-intensive bus (AFAIK,
USB is still essentially an interrupt-driven technology, causing CPU use every
time a packet travels the wire), offloading the encoding to an already-working
CPU might be a poor decision.

SCSI over USB :).  But really, Firewire/iLink/IEEE-1394 is infinitely
superior for bulk data, currently 400Mb/s vs. USB's relatively pathetic
12Mb/s.  Of course, nobody makes MO drives that can keep up with data
transfer rates that fast.

MD: DJ minidisc players checked out

2000-03-15 Thread Rev Simon Rumble


Well I found a place that has the Denon DJ minidisc player in Akihabara
(Tokyo).  It was, from memory, 60,000 Yen which you can convert to your
local currency at www.currency.co.nz -- for me it puts it around the same
price as an SL1200, which I guess makes some sense.

My first impression is that it's very big.  The pads to select tracks or
loops take up an inordinate (and I think excessive) amount of space,
making the unit about as big as a normal turntable.  I'd like to see one
that's just a little larger than a portable MD player.  COnsidering any DJ
using the thing won't be able to rely on the venue providing it, you'll
need to lug them around everywhere you go.

Otherwise they're pretty damn good.  Quite likedc it.  Pitch and Speed
control wass sensible and easy to use, loopiong worked quite well.  The
price seems a little high, since a portable is so much cheaper and you'd
need two of them.  But if you're dead keen on being a DJ, probably not a
bad option.

http://www.dvdutils.com is a great site about stuff like this. Bear in mind
that you not only need a region free DVD-rom drive, you also will need to
region-free crack the dvd playing software you are using. Just to warn you
though, it may be difficult to find a region free drive now as apparently
all drives manufactured after January 1st 2000 are meant to be region locked
although there will probably still be ways around this ;)

USB 1.1 maxes out at 12Mb/s (bit vs. Byte), or 90MB/minute.  A 74 minute CD
is 640MB, or ~8MB/minute.  Kick the math around and, after you figure in
something like a 5% loss due to overhead, you can dump raw, 16-bit PCM down 
the USB pipe about 10 times faster than real-time playback.  Encoding on
the host machine saves you nothing.

The entire point of USB is to move hardware *outside* of the host machine.
If you put the encoder inside, then there is no reason for a USB device.

Re: MD: MD to CDR

On Tue, 14 Mar 2000, J Coon wrote:

Hi,

 I know there must be several ways to do this, but I don't find any links
 to it on the MD community web page.   Every so often, people ask how to
 do this, 'cause they recorded something with their portable and want to
 share it with some that aren't enlightened.  Is there a web page I can
 point them to for the options on how to do it?  It seems there is plenty
 on going the other way, but to make these things more useful to
 musicians, they need a way to record on  MD, and then copy it to a CD to
 give or sell to a potential market for their music.

This is how I'd do it. A easier choice for musicians maybe to feed
the MD to a CDR standalone recorder. But if you're concerned about
perfection, you'd better:

- have a MD deck with digital out. They're almost cheaper than
portables...

- have a soundcard with digital in.

- Use a wave editor to transfer the MD contents to sound files,
recording digitally.

- Enhance it, by using normalization, and maybe some expansion or
compression, or even denoising, although the best way is always to have
good recorded material. 

- Toast it.

If the MD deck has a control bus (eg. S-link) and you're going to
that on a regular basis, it could be worth to implement some automation,
in order to record to different files, and maybe generate CD-Text entries
using the MD title and track labels. 

If you're interested on this, and do Linux, check
jukebox-control.sourceforge.net, as almost all the process mentioned
previously could be automated easily with some scripting with the aid of
tools like brec, sox, cdrdao etc... and the perl S-Link library
functionality that is being implemented.

That's all!

Do they let you control other things? Like, can you use it to change
satellite channels automatically, and start recording them at specified
times, even controlled by a computer would work? If it did this, could it
stop or insert music into the time where it would switch channels and cut
the show in when the dish arrives on the channel? I really don't want to
record silence, and if it can't stop automatically while it switches, at
least to fill the space with something.
Is there any cheap c-band receivers that are likely to get most radio talk

than in the unit.

Even if a high-speed ATRAC chip is used as opposed to software ATRAC, I

Re: MD: Here's a creative one, let's see if any of you can figure it out.

2000-03-15 Thread jds


Ok, here's a creative guess (and only a guess)
But, I'm willing to bet there may be something wrong with the
motor, that's spinning the drive, and consequently not properly
filling the ram buffer.  It's trying to play back as best it can
but if the disc isn't spinning properly (at most angles) it's
getting stuck.  Howerver due to the design of the unit (ok, it's
starting to get deep) at the one angle you've found it to work
fine in, has the md, and the motor at a neutral balance point for all
the hardware that makes up the unit, and is the one position it plays
properly, since there is less resistance for the motor to spin
the disk against.

Alright, you asked for creative, you get creative...

Seriously, I'm ballparking this one because of problems I've had
in the past with portable cd players that are on their last legs (and
a Sony Playstation that only works properly if its inverted (don't ask
I just about flipped (no pun intended) when I was told that would fix 
the problem)).

If this is the case, you're gonna definitely want to return the unit for
another one.

good luck
